To understand how to defend attacks, one must first learn how to attack defenses.

Mindgard’s research has produced 150+ publicly disclosed AI vulnerabilities. The intelligence gained from those discoveries continuously strengthens the platform, helping organizations identify exploitable attack paths, including emerging agentic AI threats, and stay ahead of evolving attacks.
