02
Contextual risk scoring

03
Automated response

Auto-quarantine malicious messages, roll back compromised accounts, and close low-risk alerts so your analysts focus on real incidents.

Explainable AI detection engine

Every decision comes with human-readable reasoning and supporting signals so your security team can see exactly why an email was allowed or blocked.

  • Layered AI models for identity, content, behavior, and intent.
  • Detections adapt in hours to new campaigns and attack techniques.
  • Full audit trail for compliance, incident response, and board reporting.
