Key features
  • 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
  • Forward-Deployed Researchers provide end-to-end model training and optimization
  • Custom evaluation suite development from real tasks
  • Production-ready deployment with cost-quality trade-offs
  • Deployment flexibility including on-premises and VPC options
  • Data security with no retention and full traceability
  • Continuous model improvement from production traffic
  • Customer ownership of model weights and training recipes
What makes it different
  • 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
  • Customers own specialized models trained on proprietary data, not rented general-purpose models
  • Achieve frontier-level quality at lower costs through specialized training
  • Five years of experience with diverse post-training and optimization methods
  • Models ship production-ready in weeks with ongoing improvement capability
  • Secure deployment with no data retention and auditable access controls
