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
  • Durable decision records that survive client disconnections and restarts
  • Reduces median approval time significantly in production environments
  • Unified API across multiple approval surfaces without building custom dashboards
  • Source-scoped identity for independent credential rotation across runners
  • Built-in monitoring for stalled background work with heartbeat watches
