Horizon 3 AI
Provides an autonomous SaaS platform for continuous penetration testing and vulnerability management to help organizations proactively secure their networks
About Horizon 3 AI
Horizon3.ai is a cybersecurity startup specializing in autonomous penetration testing (pentesting) solutions. Founded in 2019 and headquartered in San Francisco, CA, the company offers a Software-as-a-Service (SaaS) platform called NodeZero. This platform allows businesses to simulate cyber-attacks on their own systems to identify vulnerabilities and ineffective security measures. Unlike traditional pentesting methods, NodeZero is self-service, meaning it doesn't require ongoing human intervention or the installation of persistent software agents, making it safe to use in live production environments.
