Four systems, not one maturity story

Security Copilot Agents is a broad agent framework. Security Alert Triage Agent performs a narrower Defender classification workflow. Project Perception coordinates red, blue, and green agents in a limited public preview. MDASH is a vulnerability-discovery harness used internally and tested with a small private-preview customer set.

What actually differs?

The triage agent can classify supported alerts and is managed through administrator permissions and feedback. Project Perception coordinates multi-agent playbooks and requests approval for critical decisions. MDASH discovers and validates software vulnerabilities but does not establish autonomous patch deployment.

Availability matters

Project Perception remains invitation-only limited public preview in the reviewed source. MDASH remains limited private preview for external customers. A buyer cannot safely infer broad commercial availability from internal Microsoft use or benchmark headlines.

Evidence limit

Microsoft publishes substantial architecture and workflow documentation. The corpus does not contain qualifying independent production-effectiveness evidence for these systems. Benchmark scores reported by Microsoft remain vendor-reported unless the benchmark operator or an independent evaluator publishes the scoped result.
