Now I'll turn the call over to Jay.
Thank you, Bill. We are pleased to report another strong quarter. In Q3, we delivered 63% year-over-year revenue growth, 54% billings growth, and 15% free cash flow margins, all while investing for high growth. While most public SaaS companies are happy to get to rule of 40, we again exceeded the rule of 70 based on revenue growth and free cash flow margins. With our increased guidance today, we expect to achieve the rule of 80 for the full year. We are not only delivering excellent growth, we are also delivering strong profitability. We are disciplined in making investments for innovation and go-to market scale. With the breadth and depth of our ever-expanding zero trust platform, we can efficiently sell to our growing base of enterprise customers.
We believe our clear focus on securing large enterprises makes us the partner of choice for our customers' zero trust security journey. While there are broader macro challenges and economic uncertainties, we have seen an increase in large multi-year commitments for multiple product pillars of Zscaler platform as periods of uncertainty can act as a catalyst for change. This, coupled with growing cyber threats such as ransomware, are driving IT leaders to transform security from castle and moat security to zero trust architecture. In this environment, customers cannot risk transformational and mission-critical projects with immature offerings from unproven vendors. As the pioneer and category leader in security service edge, or SSE, with the widest and deepest offerings, Zscaler is the trusted partner for vendor consolidation, cost savings, increased user productivity, and better cyber protection. We are adding new global 2,000 customers at a record pace.
In the last two quarters, we added close to 80 G2K customers. Now 40% of the Fortune 500 and 30% of Global 2000 companies trust Zscaler to secure their digital transformation. Approximately half of our Global 2000 customers have both ZIA and ZPA, and I am excited to report that ZPA has surpassed over $200 million in annualized revenue. In Q3, we had significant growth in new $1 million+ ACV deals across major geographies and customer verticals. We are seeing an acceleration in multi-year, multi-product pillar deals as enterprises are racing to transform their business. We provide a path for large strategic customers to ramp into larger and longer commitments for our entire transformational platform, not just for elements of it. This is driving a strong growth in bookings with the total value of our committed future revenue reaching a key milestone.
It has surpassed $2 billion. Now, let me highlight some customer deal wins during the quarter. As I mentioned before, I believe all customers will ultimately purchase ZIA, ZPA, and ZDX for all users. This quarter, we have seen ample evidence that customers are buying ZIA, ZPA, and ZDX together, providing Zero Trust security for users with fast user experience. In a new logo win, a global 500 food services conglomerate headquartered in Europe purchased ZIA, ZPA, and ZDX for all 100,000 users. Leveraging our globally distributed SSE platform, this customer is consolidating dozens of different vendors' point products across hundreds of locations in 45 countries. The customer was most excited about having a single Zero Trust security policy framework for inline inspection across its business units in every location.
Given the significant cost savings, up-level security, and improved user experience across the company, the CEO and CFO signed off on this non-budgeted four year commitment. In addition, they started a paid pilot for our Zero Trust for Workloads offering for their sizable AWS footprint, which we are very excited about. Next, in an upsell deal, a global top 10 oil and gas customer headquartered in Europe, after deploying ZIA and ZPA for 100,000 users, purchased ZDX for all 100,000 employees. ZDX is delivering immediate value by reducing the customer's time to troubleshoot performance issues by 50% to 80% while consolidating 40 legacy performance point products. In addition, the customer upgraded to a newly introduced ZPA Transformation bundle that includes browser isolation, application protection, and deception services. This is a four year deal that increased the customer's annual spend by over 70%.
This customer's journey with Zscaler is remarkable. I remember sitting with the chief architect in their office finalizing the purchase of our ZIA professional bundle six years ago. Since then, their annual spend has increased over 14x to well over $10 million. Next, we look forward to working with them on Zero Trust for Workloads. In an upsell win, a Fortune 500 bank in Asia that has deployed ZIA for over 50,000 users purchased ZPA and ZDX for all 50,000 employees. This is another example of a large customer buying ZIA, ZPA, and ZDX for all users.
While the immediate objective for this deal was to replace a legacy multi-vendor VPN infrastructure, ZPA was selected to implement Zero Trust access by establishing an application-level policy where users connect to specific applications, not to a network, hence achieving app segmentation without having to do legacy network segmentation. ZPA did not just replace VPN, it's eliminating the need for the entire inbound DMZ, including DDoS protection, app delivery controllers, and firewalls, generating a payback on their Zscaler purchase within six months. Because of the substantial ROI, even in a tougher macro, Zscaler can help reduce cost while driving transformation. Our integration with Microsoft's E5 suites across ZIA and ZPA was also an important decision factor for them. This latest purchase more than doubled the customer's annual spend. ZIA, ZPA, and ZDX together form a complete solution to implement Zero Trust for users.
Our next immediate big opportunity is Zero Trust for Workloads powered by the same core ZIA and ZPA technology. Let me highlight a few exciting wins in this area. An existing Fortune 100 financial services customer with ZIA deployed for 60,000 users purchased Zero Trust for Workloads to protect 50,000 workloads spanning across multiple data centers and public clouds. This eliminates the need for virtual firewalls and site-to-site VPNs. This multimillion-dollar ACV deal is our largest workload deal to date and more than doubles the customer's annual spend. The customer now protects both users and workloads under single policy framework, enhancing their cyber protection, providing visibility and simplifying operations. Lastly, let me discuss a new customer purchasing all four product pillars together.
An elite research university purchased our comprehensive ZIA, ZPA, and ZDX offerings for 35,000 users and Zero Trust workloads for over 3,000 workloads for their multi-cloud environment. Their CIO's top priority is to eliminate the risk of legacy VPNs and lateral threat movement as universities are increasingly becoming a target for ransomware and intellectual property theft. Also, a critical requirement for this win was our Zero Trust platform meeting the criteria of Zero Trust framework as recommended by NIST. We closed this three year, eight-figure deal through AWS Marketplace. I'm very happy with our continued success in expanding our routes to market via cloud marketplaces. Next, I'm excited to highlight U.S. federal government, where we are having considerable momentum. Driven in part by the president's executive order, we are seeing increased interest in our Zero Trust exchange across all levels of the government.
We are excited to help our country dramatically improve our security posture while significantly reducing legacy IT costs. We have the highest level of FedRAMP certifications for ZIA and ZPA. In addition, ZPA is the only Zero Trust solution with DoD IL5 certification. There are only a select few cloud companies that have this level of certification, and there's no other cybersecurity company at this level. IL5 certification is an important differentiator for us. Let me highlight two new customer wins this quarter where this was an important factor. Plus, a defense contractor that purchased ZIA and ZPA in a six years, seven-figure ACV deal. Second, a DoD unit also purchased ZPA for secure access to SAP instances in AWS GovCloud.
Two important considerations for our ongoing success in the federal market are, first, ZPA is the only cloud security service with FedRAMP high authorization for Zero Trust remote access. We connect users to applications and not to the network, eliminating lateral threat movement, a core principle of Zero Trust architecture that can't be achieved by next-gen firewalls or cloud VPNs. Second, ZIA's proxy architecture, which inspects TLS encrypted traffic at scale, delivering superior security. Our proven track record running the world's largest inline security cloud makes Zscaler the obvious and trusted partner of choice for governments and enterprises. We now have 288 customers exceeding $1 million in ARR, an increase of 77% year-over-year. We deliver a mission-critical service that requires unmatched reliability and availability for an inline cloud.
There is no compression algorithm for over 10 years of operational experience running such a cloud. An example of our proven scale is that Zscaler processes over 240 billion transactions in-line per day, which is more than 20x the number of Google searches per day. Now, let me share a few observations about our high net retention rates, which has exceeded 125% for the last six quarters. We made a number of investments in customer success services, technical account managers, partner services, and certification of partners, which together are driving a faster and greater adoption across our broad portfolio. We have a solid blueprint for accelerating value delivery, which is driving upsells.
All of these investments result in happy customers, demonstrated by our net promoter score or NPS of more than 70, which is more than two times that of an average SaaS company. Next, let me now highlight our rapid pace of innovation. After having built the most comprehensive platform to provide Zero Trust for users, we are now expanding it for Zero Trust for workloads. Unlike scores of vendors who offer point products for cloud-native apps, Zscaler has developed a fully integrated CSPM, CIEM, and infrastructure as code scanning with a common backend and fully correlated actionable dashboard. Gartner calls this functionality CNAPP, but we have moved beyond CNAPP by integrating the threat and data awareness from ZIA and ZPA. We will be highlighting it and other innovations at Zenith Live, our annual cloud summit, next month.
We enhanced our AI ML engine for ZDX, our fastest growing new service, to leverage billions of telemetry points from millions of users to improve digital user experience. It cannot only automatically figure out what and where performance issues are, but can also provide information about the quality of voice, video, and screen sharing due to our integration with Microsoft Teams and Zoom. We have also integrated ZDX with ServiceNow, making customer end user support far more efficient. ZDX also got certified and became available on our federal cloud. Our ThreatLabz security research team is tracking over a dozen APT groups and getting better reconnaissance about their tools and behavioral patterns, resulting in higher order threat intelligence.
This specific threat intel, coupled with our massive cloud effect from 240 billion transactions and 300 trillion signals per day, enables Zscaler to deliver better threat protection than other vendors. Moving beyond users and workloads, we are now bringing Zero Trust to IoT and OT systems, a large emerging opportunity. Today, Siemens and Zscaler announced the availability of an integrated all-in-one solution to accelerate secure access to OT systems. Our joint development with Siemens brings the benefits of Zscaler to factory and industrial control systems. We are thrilled to have Siemens, a long-standing customer, as a development and go-to market partner. In closing, in spite of uncertain macro conditions, we continue to see strong demand for our services. We are in a strong financial position, and we will continue to aggressively invest in our business.
We are focused on hiring and developing talent and creating a culture that rewards innovation at all levels. We have grown our global organization to approximately 4,500 employees who are energized by our shared mission to secure the hyper-connected world of cloud and mobility. We grew our total sales and marketing headcount by 54% year- over- year, and we remain focused on investing in our go-to-market machine. In today's competitive hiring market, Zscaler is a destination for top talent. To drive continued growth in hiring and to build on Zscaler's high-performing hybrid work culture, this month we welcomed Brendan Castle, Google's former Global Head of Talent Acquisition, as our new Chief People Officer. Brendan has proven experience in building highly motivated and productive teams at scale.
With app transformation already mainstream, network and security transformation is also becoming mainstream, which we pioneered with our Zero Trust Exchange. We believe customers trust Zscaler more than any other provider for securing their cloud journey. Recent uncertainty in the macro environment is driving customers to accelerate their network and security transformation with our integrated platform, resulting in a reduction in cost, complexity, and business risk. We are adding a record number of Global 2000 customers, now with 30% of Global 2000 and 40% of Fortune 500 customers trusting Zscaler. These demanding customers are making large multi-year commitments to our platform. We are not just growing rapidly at any cost. We are also profitable and delivering efficient growth. We will continue our disciplined investment in innovation and growth to capture the large and growing opportunity ahead of us.
Now, I'd like to turn over the call to Remo for our financial results.
Thank you, Jay. As Jay mentioned, we are pleased with the results for the third quarter of fiscal 2022. Revenue for the quarter was $287 million, up 63% year-over-year and up 12% sequentially. On a year-over-year basis, revenue growth exceeded 60% for the third straight quarter, driven by strong customer demand for our Zero Trust platform. ZPA product revenue was approximately 18% of total revenue, growing 87% year-over-year. From a geographic perspective, we had broad strength across our three major regions. Americas represented 52% of revenue, EMEA was 33%, and APJ was 15%. APJ continues to be our fastest growing region, with revenue growth of 105% year-over-year.
Our total calculated billings grew 54% year-over-year to $346 million, with billing duration comparable to a year ago and above the midpoint of our normal 10-14 months range. Our remaining performance obligations or RPO grew 83% from a year ago to $2.216 billion. The current RPO is 49% the total RPO. Our strong customer retention rate and our ability to upsell the broader platform have resulted in a high dollar-based net retention rate, which was again above 125%. We had 288 customers paying us more than $1 million annually, up 77% from 163 in the prior year. I'm very pleased with the pace at which we're adding these $1 million ARR customers. We increased by 37 customers in the quarter.
The continued strength of this metric speaks to our large enterprise focus and the strategic role we play in our customers' digital transformation initiatives. We added 140 customers in the quarter, paying us more than $100,000 annually, ending the quarter at 1,891 such customers. Turning to the rest of our Q3 financial performance. Total gross margin of 80.6% was approximately flat quarter over quarter and year over year. Our total operating expenses increased 11% sequentially and 70% year- over- year to $204 million. Operating expenses as a percentage of revenue was 71% compared to 68% in the year ago quarter due to a partial return of T&E. Operating margin was 9%, and free cash flow margin was 15%.
We continue to expect data center CapEx to be around high single-digit percent of revenue for the full year. We ended the quarter with over $1.66 billion in cash equivalents, and short-term investments. Now moving on to guidance and modeling points. As a reminder, these numbers are all non-GAAP, which excludes stock-based compensation expenses and related payroll taxes, amortization of debt discount, and amortization of intangible assets. We are once again increasing our guidance across all metrics. For the fourth quarter of fiscal 2022, we expect revenue in the range of $304 million to $306 million, reflecting a year-over-year growth of 54% to 55%. Gross margins of 79%.
I would like to remind investors that a number of our emerging products, including ZDX, workload segmentation, and CSPM, will initially have lower gross margins than our core products because we're more focused on time to market and growth rather than optimizing them for gross margins. Operating profit in the range of $33 million to $34 million. We have more in-person events this quarter, including customer events, Zenith Live, and RSA conferences. Net loss on other income of $500,000. Income taxes of $3 million. Earnings per share of $0.20 to $0.21, assuming approximately 146 million to 147 million fully diluted shares. For the full year fiscal 2022, we are increasing our revenue guidance to approximately $1.078 billion, or year-over-year growth of 60%.
Increasing calculated billings to a range of $1.425 billion to $1.43 billion, or year-over-year growth of approximately 53%. Increasing our operating profit to a range of $106 million to $108 million. Increasing our earnings per share to a range of $0.64 to $0.65, assuming approximately 147 to 148 million fully diluted shares. Free cash flow of $215 million, reflecting free cash flow margin of approximately 20% for the full year. With a revenue growth outlook of 60% and free cash flow margin of 20%, we expect to operate at the rule of 80 for the full year. With customers increasingly adopting the broader platform with longer-term commitments, we plan to invest in capturing our large market opportunity.
We have confidence in the durability of our business model with very high contribution margins after the initial land and proven ability to retain and upsell to our enterprise customer base. We will balance growth and profitability based on how our business is growing, but we'll continue to prioritize growth, which we believe is in the best interest of our shareholders, employees, and customers. Operator, you may now open the call for questions.
Thank you. As a reminder, to ask a question, you will need to press star one on your telephone. To withdraw your question, please press the pound key. Stand by as we compile the Q&A roster. Our first question comes from Andrew Nowinski of Wells Fargo. Your line is open.
Great. Thank you. Congrats on another amazing quarter. I wanted to ask about your federal demand. Jay, I think you said you're seeing considerable momentum in the U.S. federal this quarter or this, which seems to be an uptick from Q2, where I think it was maybe one of the underperforming sectors. Just wondering if you could comment on maybe what changed and what caused that uptick in demand this quarter ahead of their, you know, the usual budget flush in calendar Q3.
You know, Andrew, I'll start it. You know, last quarter in Q2, our federal was low single digit of new and upsell. In Q3, you know, it was mid-single digit. Definitely an uptick. Also on a go-forward basis, you know, we do see federal as being an important contributor to Zscaler. We feel that we're well-positioned in the federal market. I'll let Jay speak more to that.
Yeah. Andrew, as you know, President's executive order is to implement Zero Trust Architecture, and it's well aligned. It actually aligns with what we have done.
To be successful in federal, you need two things. One, you need the right architecture, Zero Trust, which we have. Two, you need FedRAMP certifications. We have the highest FedRAMP certifications. Now there's a timing issue as well. White House issued a memo setting a timeline for agencies to achieve Zero Trust architecture within two years. These plans are being submitted and more budgets are becoming available. All of this is positive long-term development from our point of view. However, Fed opportunities always take time.
That's great. Thanks, guys. Keep up the good work.
Thank you.
Thank you. Our next question comes from Alex Henderson of Needham. Your line is open.
Great. Thank you very much. I've been listening to a lot of people trying to get into this Zero Trust market, and one of the things that really strikes me as highly differentiated is, one, the policy implementation mechanics are so radically different than what you're doing versus the traditional perimeter defense. And then second is the sharp increase in attacks that we're seeing in terms of encrypted traffic. Received a report today talking about over a 300% increase in encrypted attacks over the last year. Can you talk to the relevance of those two data points or those two, you know, concepts relative to your platform and how you solve that better than, say, alternative vendors?
In that context, can you just address Cloudflare's comments that they're getting more aggressive in this space? Thanks.
Yeah. Thank you, Alex. First of all, Zero Trust implementation. People sometimes build a little VPN replacement, they call it Zero Trust. What we built with Zscaler Private Access is a platform that replaces the entire inbound DMZ. Literally, you need nothing between Zscaler and the workload and application running. In fact, on top of that, we further expanded to add browser isolation, app protection, integrated deception, and AI/ML-based policy that can help you do segmentation. It's because of that you're winning ZPA deals big time. That's one part. The second part was attacks. First of all, for someone to attack, they need to find you. With our Zero Trust architecture, your applications hide behind Zscaler. They can't even find you.
With the next part of attacks is, and this is encrypted attacks, for that, you need a proper proxy architecture that actually terminate connection, look at the packets and everything, decrypt them, find them, and take care of them. For that, we have built a very, very highly scalable architecture that sets us apart, that scales like nothing else out there. It's combination of these things with 10+ years of experience running a massive inline cloud is what sets us apart from others. Now, regarding some of the competitors coming from CDN market or DDoS or DNS market, right? Those guys generally have been focused on servers. We started focusing on users to start with. It takes a lot of time and experience to build that richness and breadth of functionality we have built with ZIA, ZPA, and associated functionality.
I think it'll take a long, long time for someone to try to catch us, and we aren't sitting. We are innovating at a very fast pace.
Thank you very much.
Thank you.
Thank you. Next, we have Hamza Fodderwala of Morgan Stanley. Your line is open.
Hey, guys. Thanks for taking my question. So one question for Remo. I'm wondering if you can give us a little bit more color on how you're thinking about the margin trajectory going forward. It seems like you wanna continue hiring against the market opportunity that you're seeing. You know, Zscaler's obviously been more of a destination for talent in the last couple of years, and particularly the incentive structure around the stock, a lot of employees have done well. How are you thinking about that incentive structure between cash and stock going forward, given that we're probably gonna be in a more difficult equity market in general, and just the pace of hiring relative to what you've done in the last couple of years?
Those are a lot of questions.
Yeah.
Yeah. Let me see if I can go through and just kinda give you know, my view and maybe Jay can help that also.
Sure.
You know, we've you know currently we're at the rule of 80. That's what we're projecting, you know, for, you know, this year. The way we, you know, define the rule of 80 is our revenue growth and also free cash flow margin. Our free cash flow margin this year we're projecting to be 20%. It was 20% last year. We're in a unique position, you know, to really, you know, take advantage of this market opportunity because we've got significant, you know, cash flow coming into the company as well as we're in the early stages, you know, of this market. We're gonna continue to make investments as we go forward. Those investments are gonna be across the board, you know, throughout the organization.
We're gonna, you know, our goal is to get to a $5 billion ARR company. We're building the infrastructure in place to do that. Related to, you know, employees and incentives, you know, with stock options and, you know, just cash incentives. You know, the cash incentives, you know, we talked about on the last call, you know, related to, you know, with the frothy environment, you know, last quarter with a lot of startup companies and PE companies or PE-backed companies giving really big packages. We adjusted, you know, our merit to reflect, to get our employees, you know, at market level. From a cash compensation perspective, you know, we're in pretty good shape. Regarding stock, you know, stock, you know, all companies basically have decreased, you know, stock prices. What we're doing is we're taking a look at that, you know.
No decisions made, you know, at this point, you know, regarding, you know, what we're gonna do from a stock perspective. What I can say is our stock-based compensation, as we go forward, will decrease as a percentage of revenue. What happens is that when you get to a certain scale as a company, you know, very large companies, their stock-based compensation goes down. We'll follow the same path as the large companies. You'll see your stock-based coming down over a period of time. Regarding the pace of hiring, you know, and again, we're seeing all the things that you're seeing, you know, related to the global macro environment. We're not seeing it. You know, from our perspective, you know, we are, you know, strategic for our customers.
You know, as Jay talked about, you know, our deal sizes are getting large. You know, our strategic nature and our engagement with our customers is increasing. Our plan is to continue the pace of hiring, and if we can increase the pace of hiring, we will. Now regarding, you know, color related to, you know, operating profitability and also, you know, growth. We'll put growth as number one. Now we're mindful, Jay and I are mindful of operating profitability, and we're old school, quite frankly. We look at the bottom line. What we see is a huge market opportunity. Huge. We feel we're the leader in that market. We will continue to invest, and we'll do it on a prudent basis that we feel is the best interest of our shareholders and our employees.
If I may add two quick comments to what Remo said. With very high growth margins and unit economics, it becomes easier for us to invest in businesses. Secondly, the hiring environment is actually getting easier. We are hearing of high-flying companies that raised funding and multi-billion dollar valuations last year, they're starting to lay off people or freeze hiring. Companies that are spending to grow at any cost are now starting to slow down. We will keep on accelerating our plan because our customers want to leverage Zscaler to accelerate their transformation because they want to be competitive in HR.
Very helpful, gentlemen. Thank you for that.
Thank you.
Thank you. Next, we have Matt Hedberg of RBC Capital Markets. Your line is open.
Great. Thanks for taking my questions, guys. Congrats. Jay, what really stood out to me was the success in large deals and multi-product sales. I think especially impressive given the partner momentum in some of these large deals. Can you talk about the importance of hyperscalers? I believe you called out one in an eight-figure deal. Is there even more that you guys can do to drive even faster partner contribution? 'Cause it really does feel like that flywheel is really kicking in well.
Yes. The partner momentum comes from two sides. One is partners like Microsoft who have been helping us even without fulfilling through Marketplace. That momentum has been leveraged for the last several years. Now it has extended over AWS quite a bit. That's one area. The second area is being able to deliver orders through cloud Marketplace. It is one more channel for us to revenue. Our business through both AWS and Azure has been steadily growing. Zscaler is viewed as a part of a cloud transformation solution. When it's fulfilled through a Marketplace channel, it often comes out of an annual cloud spend that's already committed by the customer with a hyperscaler. That makes it actually easier in many ways. In Q3, we did one of our largest deals through AWS Marketplace.
If you recall, we did a very large deal last quarter through Azure Marketplace, and we are training AWS and Microsoft sales teams, and I think there's a good opportunity to create more leverage. These are generally larger deals. You're seeing our momentum in larger deals. In the last two quarters, we have added almost 80 Forbes Global 2000 companies to our portfolio. I mean, that's pretty remarkable, and we don't see any slowdown.
Super exciting. Thanks, guys.
Thank you.
Thank you.
Thank you. Next, we have Patrick Colville of Deutsche Bank. Your line is open.
Thank you so much for having me on, and yeah, I echo everyone else's congratulations on a very impressive set of numbers. My question is on the billings guidance, which to me was probably the standout metric of the quarter. I think above probably where many investors were expecting, so, you know, very healthy there. Can you just talk to, you know, what you guys are seeing in the pipes for fiscal fourth quarter and, you know, the health that I guess you underlined the confidence to give that strong billings guidance for the fiscal year. Thank you.
Yeah. I'll start it and Jay, if you'd like to contribute anything.
Sure.
You know, we have a strong pipeline, you know, as we talked about, we're becoming more strategic. You know, our deal sizes are getting bigger. You know, we review, you know, our pipeline, you know, with our sales organization. Based on our projections, you know, we did give a strong guide, Patrick, you know, which is basically up 6%, you know, basically guide up. The key thing is that, you know, with the world that's changed, it's been this way for a while, with applications in the cloud, and users are mobile and workloads both in the cloud and on-prem and other locations. Platform that Zscaler created really addresses this market head on.
Also, you know, the efficiency that we create, you know, for customers at a very attractive ROI, it's really what stands out. We're seeing, you know, with large customers with, you know, adopting more of the platform, which Jay has talked about, we're seeing that. You know, it is basically review the pipeline and review what we feel we're comfortable to guide to.
Yes. I think what Remo said, our projection is always take into account our pipeline, our customer engagements, but at a quantitative level, as I talk to lots and lots of CIOs and CISOs, I mean, there is a sense of uncertainty out there. They're beginning to think about how do I do my cost and complexity reduction, my consolidation, and that's where we start becoming pretty important. For that, customers are driving transformation. We help them with it. On top of that, cyber is a big issue.
When you bring all these things together, we become more important for them, and they start that discussion with, "Jay, what all security products and networking products can I replace with you?" Now we are able to actually talk about a bigger set of products that need to be removed, which actually leads to a bigger part of platform to be bought. Now, on top of that, it's interesting to see suddenly on the high-flying private startup companies, which would talk about all kinds of stuff and hiring how many employees, all that stuff is getting tempered down. That means the unnecessary noise in the market is expected to slow down. It's fascinating to see people calling us from those startups already. We are bullish about the business.
Excellent stuff. Thank you so much.
Thank you. Up next, we have Joel Fishbein of Truist. Your line is open.
Thank you. I'll echo the congrats on the great execution this quarter. Jay, I just wanna ask about workload segmentation. It sounds like you're very—I know it's early days, you're very excited about it and have some good uptake. I'm really interested in, you know, go-to-market around workload segmentation and actually IoT and OT. It doesn't seem like, you know, they're natural, you know, they have different buying centers inside of organizations than ZIA and ZPA and ZDX. Love to hear how you're gonna plan to go to market there and, you know, increase deal sizes around, you know, those specific areas.
Yeah. Very good question. You know, in Q2, we talked about how a number of our large customers are beginning to buy workloads, our zero trust workloads, but at a small scale. This last quarter, we start to see them actually buying some very large orders in this area. That, that's very encouraging. Now, in terms of the buyer and the products, the cloud protection products can be put in two broad buckets. One, what Gartner now calls CNAPP, is a collection of CSPM, CIEM type of stuff. It's API-based security. It's a new area for everyone. It's simpler to build, and we have a very good offering in that space. We revamped our CNAPP offering, which we'll be launching at Zenith Live next month.
Parallel with that is Zero Trust workload, which is taking ZIA and ZPA technology and making it available for workloads because workloads need to talk to internet that goes through ZIA engine. They need to talk to each other, which goes through ZPA engine. This is bringing Zero Trust to workloads. Bringing the two together, inline piece of it and API piece of it, sets us apart from any other vendor in the market out there. Regarding buying centers, if you really look at it, if we were selling at a lower level, buying will be very different. No matter what who buys the product, when it comes to security part, CISO is definitely involved. Our good relationships CISO are helping us with Zero Trust workload and cloud protection.
Our relationship with head of networking are helping us because in the old world, you are extending your data center to cloud with all these dedicated links out there. The area we are developing and building more relationship is the DevOps side of it. Since CISO relationship is strong, it is helping us. We are not creating an overlay team, but we do have product specialists. You need overlay teams when you're selling point products at low level. When we have been selling platform at a high level, I don't need overlay teams. I do need product specialists, which we are hiring to work with our broad sales team. Did I help?
Very much. Thank you so much. Great.
Thank you. Next, we have Fatima Boolani of Citi. Your line is open.
Good afternoon. Thank you for taking my questions. Remo, this one's for you. You know, in Jay's script, a lot of anecdotes around the multi-land transactions in the eight-figure deal momentum and the million-dollar customer momentum. What I wanted to ask you was just from a booking standpoint, I think you've called out that you are seeing a bigger multi-year commitment from some of your customers. We're certainly not seeing that impact on billings in terms of your invoicing duration. I'm curious if you can comment or share any sort of observations on your backlog and if there's any duration impact in there that we should be thinking about more critically. Thank you.
Yeah. That's a great question. You know, if you take a look at our RPO and CRPO growth, you know, on a year-over-year basis, those are committed. Those are committed deals. Our RPO growth was 83%, and our CRPO growth was 75%. You know, related to duration, you know, the duration was comparable on a year-over-year basis. There's no headwinds. We expect, you know, durations being that 10 to 14 months range. I mean, the key things from billings is calculated billings, which is calculated off of deferred revenue. That's what we actually bill. We look at the RPO and CRPO growth rates. You know, RPO is 83% and CRPO is 75%, you know, growth rate, you know, on a year-over-year basis.
Now, having said that, you know, even though those metrics are outstanding, we still feel that, you know, billings is the best measure, you know, for Zscaler. You know, because we've bound that duration period from, you know, 10 to 14 months. You know, that's so I hope that answers your question. I believe that answers your question. You know, the actual commitment that customers are making to Zscaler is quite impressive.
Yeah. Fatima, if I may add one thing. This is an outstanding quarter from lots of customers doing multi-product deals for multi years, which is very exciting.
Very clear. Thank you, gentlemen.
Thank you. Next question comes from Ben Bollin of Cleveland Research. Your line is open.
Good afternoon, everyone. Thank you for taking the question. I wanted to go back to the topic around cloud marketplaces. Remo, can you quantify how much of the business is being transacted over cloud marketplaces today or how that has evolved? Also interested in any ways we should think about the margin implications of that business versus other sales channels. Thanks.
Yeah. I mean, not much business, you know, currently going through, you know, cloud marketplace. There is business going through, but we see that as a very important channel for us. Related to margin, we expect good margins through cloud marketplace. You know, Jay, not sure if you wanna-
Yeah. One thing, the business through cloud marketplaces has been steadily growing over time, that is very good. See, for us, I don't think the driver is what's the fulfillment channel for us. I personally care about partners who actually help me with strategic sales to the customer. When Microsoft's account exec and Zscaler account execs are able to sit together with a CIO and talk through a large deal, it is extremely useful. It does help to get the cloud hyperscalers sales team more engaged because they actually do compensate it for the business that flows through the channel through cloud marketplace. We actually are putting more focus on training AWS and Microsoft sales team, which helps them and helps us.
Thank you.
Thank you. Next, we have Tal Liani of Bank of America. Your line is open.
Hi, guys. I have two questions. One, in general, I get this question a lot from investors. I'm trying to understand economic slowdown, what's the impact on your business? It's a little bit of a philosophical question, but it's a question we're being asked a lot, and I would like to hear your view on this topic. Second, we are at times of focus on cash flow and margins, and I look at your operating margin. In the last four quarters, it went down from 13% to 8.7% the previous quarter. This quarter slightly recovered. At the same time, your revenues went up by 50%, give or take. So we don't see much leverage on the margin.
The question is, if I fast-forward two to three years, if I think about margin leverage and what needs to happen for you to have serious margin upside, can you talk about the pros and cons of your operating margin? Thanks.
No, I'll start with that. You know, we absolutely do have leverage in the model. You know, in a SaaS model with 80% gross margin growing at the scale that we're growing, we, you know, we absolutely have, you know, leverage. What we talked about is that with this large market opportunity, it would be a disservice to our shareholders and our employees if we try to drive top-line operating profitability at this stage. Having said that, when you take a look at our free cash flow margin, last year it was around 20% or over 20%, and we're projecting free cash flow margin this year at 20%.
When you have that kind of, you know, free cash flow margin at the scale that we are, making the investments that we're making, in the position that we are as a company in this very large market, there's no better use of our cash or our resources than investing in the business and really executing and trying to drive our top-line growth. Having said that, we will be mindful. If you know, if we wanted to drive operating profitability, it doesn't take much. But with our free cash flow margin where it is, you know, we're very comfortable. Now, from an economic slowdown perspective, security is important. You know, companies basically are not gonna. The attacks are gonna keep coming, and they're probably going to increase.
Also, companies, you know, going through this downturn, you know, have to find areas to save money. We are efficient. Our ROI is absolutely outstanding. It is significant ROI with the highest level of security down to the deepest level. From an economic slowdown perspective, we're not seeing it currently. Now, can that change? It can. But right now, based on our pipeline, based on what we're seeing, you know, and, you know, we talked about, we're gonna continue to hire at pace. Jay and I, you know, as I mentioned before, have a lot of experience. You know, we've seen the three downturns, three or four downturns, actually, in our lifetime, our careers. Zscaler is different, and we feel we're in a great position.
We will take things into account, all things, but, you know, and driving operating profitability at this stage, you know, is really. You know, we will increase operating profitability as we go, but we're gonna be also trying to drive that top-line growth. Jay?
Yeah. Two quick comments. First of all, I do believe this uncertain-certainty is helping us because we are going to help customers with cost reduction and complexity reduction. On the other side, you know, our flagship ZIA/ZPA products, they have reached significant scale and are generating good margins. We are reinvesting that to drive the growth of new products. We have proven that when we brought ZPA on, we made it successful. We've seen, we brought ZDX on, we're making it successful. It's growing even faster than ZPA did. We have high expectations from Workload Protection as well. I think with such a large platform, we expect that we'll keep on growing fairly efficiently.
Got it. Thank you.
Thank you. Our next question comes from Roger Boyd of UBS Securities. Your line is open.
Hey, thanks. Thanks for taking the question, and congrats on the results. Just a quick question on SD-WAN. Historically, you've had some success tied to adoption there. I know Zscaler is agnostic to how customers ultimately onboard to the Zero Trust Exchange, but with some of the SD-WAN vendors facing some disruption, share losses and potential change of ownership, how do you think about those changes in terms of potential opportunities or risks?
Yeah. You know, before COVID came in, these guys used to start with, "Hmm, let's do network transformation." When COVID started two and a half years ago, SD-WAN went out the door. There's nobody working in the branch offices. Customers start to roll out Zscaler by downloading a lightweight agent, and here it goes. With that, the roll of any network or SD-WAN became really insignificant. Today, most of our customers roll it out on laptop mobile with a lightweight agent. They can work from home, they can work from office with SD-WAN, without SD-WAN. We'll stay neutral to supporting SD-WAN vendors. Our sales processes are no longer led by SD-WAN. If a customer says, "I'm rolling out SD-WAN," we are generally the preferred choice, and that's how we see it.
We don't really see any changes in the SD-WAN marketplace impacting us.
Got it. Thank you.
Thank you. Our next question comes from Joshua Tilton of Wolfe Research. Your line is open.
Hey, guys. Thanks for taking my question here. I don't believe you mentioned it in the prepared remarks, but can you talk about any impact to the business you're seeing, either positive or negative from the Russia-Ukraine crisis?
Yeah, Russia-Ukraine, it was a bigger thing a quarter ago. You know, I decided years ago not to sell in Russia. Hence, we do not have any revenue exposure in Russia or Ukraine. Cybersecurity is a global threat. It's not a regional threat. Our threat research team is tracking heightened cyber threat environment, which is making every CIO and CISO more nervous in this area. This is driving the adoption of Zero Trust architecture, and it is increasing our engagement with customers. More so in Europe. Actually, European customers are more worried about it, while Americans are too. We have some very large deals in Europe this quarter, including a couple of them I highlighted. We don't really see any negative impact of this conflict, and we remain engaged with our customers to drive the transformation. They want to become agile, competitive.
We play a role there. Then cyber on top of that. Don't see any negative impact.
Thank you very much.
Thank you. The next question shall come from Rob Owens of Piper Sandler. Your line is open.
Great. Thanks for taking my question. Wonder if you guys could drill into the Siemens partnership a little bit? I guess, Jay, more broadly, what you see as the opportunity in OT from where you sit? Thanks.
You know, OT plants and factories have been slow in changing. Typically, plants take their own time, but all these critical infrastructure attacks and cyber threats have made it a priority. Vendors like Siemens are big providers of OT systems out there. They see this as an opportunity for really providing or should I say, taking firewall and VPN-based security of OT systems to Zero Trust-based security, where you no longer connect these OT networks and IT networks, where you no longer need remote VPN to access these systems. Siemens has worked with us over the last year or so. They essentially chose us as a partner. We did joint development, where we made our technology available on their hardened OT systems, and this combined solution of Siemens and ours is now available through our customers out there.
I think it's a good opportunity for us. I think it's a matter of time when all IoT/OT systems will embrace Zero Trust, and we are positioned well for that opportunity.
All right, thanks.
Thank you. This concludes today's Q&A session. I shall turn the conference back over to your CEO, Jay Chaudhry for closing remarks.
Thank you. I want to thank you all for your continued interest in Zscaler. I also want to thank Zscaler employees, customers, and partners for delivering a strong quarter. We look forward to seeing many of you at Zenith Live, our annual cloud summit. Thank you. Thank you.
This concludes today's conference call.
Goodbye.
Thank you all for participating. You may now disconnect and have a pleasant day.
