How Sentinel Works
Understand the decision-to-boundary-to-receipt model behind Sentinel SCA.
Read guide →Learn Sentinel SCA
Sentinel SCA is a deterministic governance runtime for AI agents and autonomous systems. It validates actions before execution using identity, capability governance, policy evaluation, human approval, replay protection, execution boundaries, and tamper-evident audit trails.
Architecture
Learn how Sentinel prevents unsafe agent actions, creates signed governance evidence, and enables replayable incident reconstruction.
