Stop Unsafe Agent Actions Before Execution.
Sentinel SCA verifies agent identity, evaluates actions against deterministic policy, records signed governance decisions, and creates replayable evidence for audits, investigations, and compliance.
Built for teams deploying autonomous agents into real systems. Unsafe actions can be halted before execution, approved actions can be traced, and incidents can be reconstructed from signed evidence. Prototype proof: Sentinel has been tested around an Agri-Nexus Prime farm-control prototype using ESP32 hardware, sensors, and actuator control.
What Sentinel Prevents
Sentinel sits between autonomous agents and real systems so risky actions are governed before they execute.
Unauthorized AI Actions
Agents cannot perform sensitive actions without identity, policy checks, and an admissible governance decision.
Unapproved Automation
High-impact actions can be allowed, denied, or routed into human review before they touch infrastructure.
Missing Audit Trails
Every decision is recorded with hashes, timestamps, tenant scope, and exportable evidence for later review.
Unexplained Decisions
Teams can replay governance events and understand why an action was allowed, denied, or flagged for review.
Unsafe Infrastructure Changes
Commands that restart services, alter systems, trigger devices, or move data can be checked before execution.
Customer Trust Gaps
Signed evidence packages help prove that autonomous systems are governed, attributable, and reviewable.
System Status
Live governance infrastructure for autonomous systems.
Secure Your First Agent in 30 Seconds
Register an agent, send a signed action request, and let Sentinel evaluate it through the governance pipeline.

How Sentinel Prevents Unsafe Execution
Sentinel uses a 13-layer governance architecture to verify identity, validate capabilities, enforce policy, govern execution, and create independently verifiable evidence.
The outcome is simple: unsafe actions are stopped before execution, every decision is attributable, and incidents can be reconstructed with signed evidence.
Real-Time Governance Decisions
Every request is evaluated, scored, recorded, and replayable.

Operator Dashboard
Monitor agent behavior, review risky actions, and investigate incidents from one dashboard.
Built for Secure Autonomous Infrastructure
Agent Identity
Cryptographic identity using Ed25519 keys ensures every request is tied to a known autonomous system.
Policy Engine
Deterministic allow, review, or deny decisions ensure risky actions never bypass governance.
Governance Integrity
Every governance decision is cryptographically signed, integrity-linked, and exportable for independent verification and incident reconstruction.
Live Timeline
Operators get a real-time view of agent actions, decisions, and system behavior as it happens.
Replay & Forensics
Any event can be replayed later to reconstruct what happened and why Sentinel made its decision.
Security Scoring
Agents receive behavioral security scores based on governance outcomes and risk patterns.
