About Horizon3
Horizon3.ai is a cybersecurity company that builds NodeZero, an autonomous penetration testing and security validation platform. NodeZero safely attacks a customer's own production network the way a real adversary would, chaining together misconfigurations, weak credentials and identity gaps to reveal exploitable attack paths, then guiding teams on how to fix them and verifying the fix. The platform runs without agents and can be run repeatedly, which lets organizations continuously test their defenses instead of relying on periodic manual pentests. Horizon3.ai makes money by selling annual subscriptions to NodeZero to enterprises, government agencies and channel partners, with pricing tied to the scale and frequency of testing. The company was founded in 2019 by Snehal Antani, a former CTO of Splunk and of U.S. Special Operations Command, and Tony Pillitiere, and it sells heavily into regulated industries and the U.S. federal market.
