About Horizon3.ai

Horizon3.ai sells NodeZero, a platform that autonomously executes real attack techniques in production environments so organizations can find exploitable weaknesses, fix them and verify the fixes.

Horizon3.ai describes the problem as one of effectiveness. Its pages say that security teams do not have a tools problem, and that many siloed security tools are not designed to work together. The company says the seams between those tools are blind spots that attackers exploit. Horizon3.ai says knowing a vulnerability exists is not enough and that teams need to know whether it is actually exploitable.[5]

NodeZero is described as an autonomous platform capable of executing self-directed actions to achieve an objective. In pentesting, those objectives include becoming Domain Admin, compromising sensitive data and gaining access to critical systems. Horizon3.ai says NodeZero executes real attack techniques without agents or disruption. Horizon3.ai says its autonomous approach is delivered via multi-tenant SaaS.[5]

Horizon3.ai describes a loop of hack, fix, verify and repeat. Its pages say teams should re-test to confirm a threat is gone after a fix. The company also describes a one-click verify tool in NodeZero that starts a targeted retest.[6]

Endpoint Security Effectiveness shows how endpoint protections respond to real attack behavior, and NodeZero checks for EDR presence on each host. Horizon3.ai also sells pentesting for compliance, delivered by OSCP pentesters together with the NodeZero platform.[6][7]

The service delivers a Penetration Test Report and a Fix Action Report.[6]

Horizon3.ai says NodeZero serves customers from the Global 100 to a local hospital. Its pages also name banks, healthcare systems, energy providers, manufacturers, governments and defense contractors as organizations that rely on NodeZero.[5][9]

Horizon3.ai was founded in 2019 and is headquartered in San Francisco, CA. Snehal Antani is its Co-Founder and CEO. The company describes its team as a mix of US Special Operations, US National Security and cybersecurity industry veterans.[4][6][7][8][10]
