Helmet Security
Helmet Security is an enterprise security platform that discovers agentic-AI activity, verifies agent components, enforces runtime policies, and supports governance evidence workflows.
Published Oct 13, 2026
Helmet’s combination of existing-telemetry discovery, optional endpoint instrumentation, component verification, hooks, gateways, and evidence may suit organizations that want governance without standardizing exclusively on one gateway or one cloud. However, Noma also describes enforcement through existing gateways, EDR, MDM, and agent hooks. Lifecycle breadth and integration flexibility are therefore not established as exclusive Helmet advantages. (Vendor product site)
