NebuSec

NebuSec builds Nebu, an AI security platform for continuous protection of code and cloud infrastructure. The company says it is backed by security researchers who have found zero day vulnerabilities in Chrome and the Linux kernel, and that this team steps in when Nebu flags a serious issue. The shipping product is Code Security. It scans the full repository, reviews each pull request, and runs a daily security review, with verified findings and patches ready to merge. The product page also covers threat modeling that maps a design into a threat model for the codebase, governance of AI agents and MCP servers that touch the code environment, and tracking of third party dependencies and installed apps. The pipeline is described as agent agnostic, plugging into any model. The platform also describes continuous AI pentesting, which runs automated red teaming at a chosen cadence. Supply Chain Security and Cloud Security are shown as coming soon. Nebu is aimed at engineering and security teams that want vulnerabilities found and fixed before code reaches production. The site lists a vulnerability research team with a record of assigned CVEs and bug bounties. Access starts with booking a demo, and pricing is not published.
