Horizon3.ai
|
Horizon3.ai's mission is to help you find and fix your attack vectors before criminals exploit them. NodeZero, our automated penetration testing solution, enables organizations to continuously assess the security posture of their enterprise, including external, identity, on-prem, IoT, and cloud attack surfaces. Like APTs, ransomware, andother threat actors, our algorithms discover and fingerprint your attack surface, identifying the ways exploitable vulnerabilities, misconfigurations, harvested credentials, and dangerous product defaults can be chained together to facilitate a compromise. NodeZero is a true self-service SaaS offering that is safe to run in production and requires no persistent or credentialed agents. You will see your enterprise through the eyes of the attacker, identify your ineffective security controls, and ensure your limited resources are spent fixing problems that can actually be exploited. Founded in 2019 by industry, US Special Operations, and US National Security veterans, Horizon3.ai is headquartered in San Francisco, CA, and made in the USA. | $250M / Series E / Aug 03, 2026 | |
