About Grego AI
We find critical vulnerabilities in complex systems.
Grego AI is an AI-native security tool built around a proprietary AI security harness. It investigates complex systems—including frontends, backends, APIs, SDKs, distributed systems, blockchain and DLT infrastructure, smart contracts, and the interactions between them. Thousands of specialized agents map context, pursue parallel hypotheses, challenge candidate paths, and consolidate the strongest evidence into actionable findings.
The work
Every engagement starts from an agreed repository, component, or release at an exact commit. Grego’s proprietary AI system assembles architecture and invariant context, maps relationships across the codebase, and coordinates parallel security investigations across the code and its relevant dependencies.
The harness challenges candidate findings, expands promising paths across adjacent code and assumptions, and consolidates the strongest evidence into a focused technical report. The result records the failure path, prerequisites, impact, and remediation evidence—not a feed of raw scanner output.

Researchers
The Grego AI harness performs the primary investigation across thousands of parallel paths. Grego’s security researchers bring public work spanning protocol engineering, audit competitions, responsible disclosures, and bounty findings.
