Tenzai

What Tenzai does

Tenzai is an AI-native cybersecurity company that builds cutting-edge AI hackers to ensure enterprises deliver unbreakable code. Its platform actively hacks, exploits, and helps fix vulnerabilities across enterprise software continuously and at scale. Tenzai's AI agents discover, chain, and exploit vulnerabilities that scanners miss, across every application, continuously. It runs full penetration tests end-to-end, reasoning about applications like an expert human, discovering attack surface, chaining weaknesses, and producing reproducible exploits with evidence for fixing them. The platform is transparent and guidable, allowing teams to scope, direct, narrow, and review its reasoning at every step. It scales to every application without needing to schedule red team engagements.
