About NebuSec

Built by the people who find what others miss.

Mission

Securing the shift to AI-native systems

For years, application security has focused on finding vulnerabilities after code is written. Today, AI agents, fast-moving dependencies, and constantly changing cloud infrastructure create risk faster than traditional tools can keep up.

NebuSec provides continuous protection across code, supply chains, and cloud infrastructure — finding what’s exploitable, validating the risk, and helping teams fix it before attackers can act.
