Key features
  • Test agent behavior against explicit authority boundaries
  • Preserve separate evidence of actor choice, authorization, containment and effect
  • Bounded adversarial behavioral testing
  • Repair and retest workflows with lineage
  • Public Observatory for longitudinal research
  • Provider-neutral and framework-compatible
  • Customer-controlled assurance runtime
  • Agent-to-agent collaboration and cross-agent encounters
  • Test financial authority and spending limits
  • Open integration surface with developer tooling
  • 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
  • Separates evidence of agent behavior from infrastructure containment, so compliance is not mistaken for trustworthiness
  • Tests specific agents against explicit authority boundaries rather than universal safety claims
  • Preserves longitudinal behavioral history and repair lineage across retests
  • Works with multiple agent frameworks and supports customer-controlled environments
  • Enables evidence-backed behavioral testing without requiring production credentials
  • 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
