A leader in proactive defense through NodeZero, an advanced AI platform for autonomous and continuous penetration testing of corporate networks.
Horizon3.ai is a US based cybersecurity company founded in 2019 in San Francisco. It specializes in offensive cybersecurity, meaning it helps companies identify how they might be attacked by hackers before it actually happens.
Their main product is called NodeZero: an AI-powered “autonomous pentesting” platform. In practice:
- it simulates real cyberattacks;
- it searches for vulnerabilities, weak passwords, and misconfigurations;
- it verifies whether a vulnerability is actually exploitable;
- it suggests what to fix first;
- it automatically checks to ensure the issue has been resolved.
The core idea is to use AI “on the defensive side”: instead of waiting for an attack, the system acts as an automated ethical hacker that continuously tests the corporate network. The company refers to this as “fight AI with AI.”
Areas covered include:
- internal corporate networks;
- cloud and hybrid environments;
- Kubernetes/containers;
- password audits;
- phishing simulations;
- attack surface analysis.
It is considered a rapidly growing company in the cybersecurity/AI sector, with enterprise and government clients.
