Key features
  • Surface-specific pre-action interception
  • Policy routing with allow, observe, ask, and block outcomes
  • Local review and evidence workflows
  • MCP, skill, plugin, and package inspection
  • Layered local and team policy
  • Open source runtime under Apache-2.0
  • Offline local protection without cloud connectivity
  • Continuous GitHub leaked-secret monitoring
  • Decision audit trail and export
  • Support for multiple AI coding agents
  • X.509 certificate issuance via AWS KMS with private keys stored in HSM
  • Real-time behavioral monitoring and drift detection across eight risk dimensions
  • Content-risk scoring of agent outputs per EU AI Act Article 5
  • Automatic certificate revocation when risk crosses 0.85 threshold within 60 seconds
  • Compliance reports mapped to NIST AI RMF, NIST CSF 2.0, ISO 27001, MiCA, and EU AI Act
  • Public verification endpoint with sub-500ms response and no authentication required
  • OpenTelemetry (OTLP) export to Datadog, Grafana, Honeycomb, and Splunk
  • RFC 8693 delegation chains and signed forensics
  • Webhook event delivery with HMAC signatures and audit logging
  • AgentMail: verifiable email inbox per certified agent for regulatory communication
What makes it different
  • Open-source core runtime runs locally without cloud requirement
  • Protects against secrets, destructive commands, prompt injection, and supply chain attacks
  • No source code or secrets uploaded; decisions stored as redacted summaries
  • Only platform that issues cryptographic identity to deployed agents, monitors behavior in real time, and generates compliance reports as one unified product
  • X.509 certificates provide institutional trust standard used by banks and governments for 30+ years
  • Auto-revocation with sub-60-second SLA stops misbehaving agents without manual intervention
  • Content-risk scoring evaluates agent output language, not just actions, catching prompt injections and policy violations
  • Private keys never accessible; stored only in AWS KMS with cryptographic signing performed by KMS directly
