Hello, and welcome to CrowdStrike's Q4 and Fiscal Year 2025 Financial Results Conference Call. At this time, all participants are in a listen-only mode. After the speaker's presentation, we will conduct a question-and-answer session. Please be advised that today's conference is being recorded. I would now like to hand the call over to Maria Riley, Vice President of Investor Relations. Maria, please go ahead.
Good afternoon, and thank you for your participation today. With me on the call are George Kurtz, Chief Executive Officer and Founder of CrowdStrike, and Burt Podbere, Chief Financial Officer. Before we get started, I would like to note that certain statements made during this conference call that are not historical facts, including those regarding our future plans, objectives, growth, including projections, and expected performance, including our outlook for the Q1 and fiscal year 2026, and any assumptions for fiscal periods beyond that, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
These forward-looking statements represent our outlook only as of the date of this call. While we believe any forward-looking statements we make are reasonable, actual results could differ materially because the statements are based on current expectations and are subject to risks and uncertainties. We do not undertake and expressly disclaim any obligation to update or alter our forward-looking statements, whether as a result of new information, future events, or otherwise.
Further information on these and other factors that could affect the company's financial results is included in the filings we make with the SEC from time to time, including the section titled Risk Factors in the company's quarterly and annual reports.
Additionally, unless otherwise stated excluding revenue, all financial measures disclosed on this call will be non-GAAP. A discussion of why we use non-GAAP financial measures and a reconciliation schedule showing GAAP versus non-GAAP results is currently available in our earnings press release, which may be found on our Investor Relations website at ir.crowdstrike.com or on our Form 8-K filed with the SEC today. With that, I will now turn the call over to George.
Thank you, Maria, and thank you all for joining us today for our Q4 2025 earnings call. I'm extremely proud of the engagement we've had with customers, partners, prospects, and the market navigating a year that tested CrowdStrike. Q4 showcases the fruits of our labors, giving me strong conviction in our AI-native single platform, excellent execution, and accelerating market opportunity.
Q4 and FY 2025 highlights include Q4 net new ARR of $224 million, well ahead of our expectations, closing FY 2025 at $4.24 billion in ending ARR. FY 2025 ending ARR for cloud security, identity protection, and next-gen SIEM of over $1.3 billion, growing nearly 50% year-over-year. Gross dollar retention of 97% as customers remain firmly committed to the Falcon platform.
Q4 free cash flow of $240 million, and for the full year, we delivered free cash flow of $1.07 billion, or 27% of revenue, setting a new record and for the first time exceeding $1 billion in annual free cash flow. CrowdStrike is the first cybersecurity ISV to cross $1 billion in deal value on AWS Marketplace in a single calendar year, setting a new standard for ecosystem execution.
And record and accelerating FY 25 total contract value of $6 billion, the first and only pure-play software cybersecurity company reported to achieve this metric, which increased 40% year on year, showcasing the scale and commitment of customers' long-term cybersecurity consolidation on the Falcon platform. Everyone loves a comeback story, and that's exactly what we've started experiencing in Q4 as we've closed out the year. The results tell our story.
One, we've never been closer to our customers and partners with market-leading customer satisfaction levels. Two, we're playing best-in-class defense as well as offense with our Falcon Flex subscription model. And three, our innovation engine hasn't missed a beat. The Falcon platform has never been more market competitive, whether that's winning new logos or in third-party analyst research. We find ourselves placed at the epicenter of a rapidly evolving demand environment.
A new administration, a new wave of technology, and a new threat landscape necessitate all businesses to evolve their cybersecurity programs. Consolidation, cost reduction, and automation are now the accepted enterprise and federal priorities. These priorities are accelerating the shift from ineffective, narrow, or duplicative point products. I'd like to share AI-specific trends on the broader demand environment and how these trends relate to CrowdStrike. First, AI experimentation is just starting to evolve into AI outcomes.
Second, we're in the midst of a rapidly accelerating geopolitical AI arms race, and third, winning the AI war requires the very best data and battle-tested innovation engine. Commenting on the shift from AI experimentation to AI outcomes, we're still in the early but rapidly evolving innings of the AI revolution. Businesses and governments across the globe are looking for their AI investments to yield both improved efficiencies and novel outputs.
At CrowdStrike, we're requiring every team and function to leverage the power of AI. We expect these investments to play critical top and bottom line roles on our path to $10 billion in ARR. In the broader market, businesses are equally grappling with how to secure their environments in this AI age. Here's my take on what this means. First, more AI everywhere means more data, more access, and more processes, services, and products requiring cybersecurity.
The locales of AI adoption are either in cloud workloads or data centers or even on edge devices, all of which we are market leaders in securing with AI-native technology that stops the breach. Second, more access to more third-party and in-house agentic applications and services requires rethinking identity and data protection. Who is accessing data and where is it traveling matters more now than ever before.
And third, securing AI starts a broader enterprise data discussion. I'm seeing CISOs, CIOs, and CEOs going to the drawing board to reinvent their technology stack with AI-powered platforms of record for their next decade and beyond. And for security, it's even more pressing. For our customers, Falcon has quickly become their AI-native SOC. Charlotte AI, our generative AI security analyst, is a SOC analyst's best friend and already driving tangible AI outcomes.
