About

Nebula Security is an AI-native cybersecurity company founded by world-class hackers. Nebula Security provides Mythos-level cybersecurity reviews and product security auditing, conducted by our state-of-the-art AI agent and world-class hackers themselves, covering everything from code-level vulnerabilities to architectural weak points. We were the first team to build an nginx RCE and the first to root Android 17. Our co-founders include members of the world’s No. 1 CTF team, DEF CON winners, Black Hat speakers, and PhD in cybersecurity. We have won $400K in bug bounties by exploiting the Linux kernel and Chrome browser. “Audited by Nebula Security” is a mark of serious security credibility: a signal to customers, investors, and partners that your product has been reviewed by the world’s best hackers.
