Purview is a thing or so we heard…or as my cat says it …Purrrrrr-view.
Words of Wisdom:
“When you don’t know how much to pay someone for a particular task, ask them, “what they think is fair” and their number usually is.”

Key Project Perception Details
Project Perception is Microsoft’s new multi-agent security system that coordinates specialized AI agents across three roles:
Red team agents – continuously map attack paths and probe for weaknesses before adversaries can exploit them
Blue team agents – investigate signals, correlate context, and prioritize real risk
Green team agents – remediate findings and harden the environment
It runs as a closed-loop system that reasons over Microsoft security signals, organizational context, and threat intelligence. High-impact actions remain under human control. Public preview began August 3, 2026, initially inside the Microsoft Defender portal, with plans to expand across the Microsoft Security portfolio. Pricing uses Security Compute Units (SCUs).

What’s New in Defender (August 2026)
What’s new in Microsoft Defender XDR | Microsoft Learn
Project Perception public preview (Red / Blue / Green agent teams for attack simulation, investigation & remediation) – available in Microsoft Defender starting August 3
MAI-Cyber-1-Flash integrated with MDASH – specialized cybersecurity model delivering ~96% on CyberGym at roughly half the previous cost by handling ~90% of routine tasks
Daily Defender Dispatch – August 20, 2026
Daily Defender Dispatch: Project Perception Public Preview Live + MAI-Cyber-1-Flash
1. Project Perception Public Preview is Live
Microsoft’s new multi-agent security system entered public preview on August 3 inside the Microsoft Defender portal.
It coordinates three specialized agent teams:
Red – continuous attack-path mapping and proactive probing
Blue – investigation, prioritization, and detection engineering
Green – remediation and hardening
Humans retain final control over high-impact actions. Access it via the Perception blade in the Defender portal.

2. MAI-Cyber-1-Flash + MDASH
Microsoft’s first in-house cybersecurity model (MAI-Cyber-1-Flash) is now powering the MDASH multi-agent vulnerability harness. It handles the majority of routine tasks and escalates only the hardest work to larger models (e.g., GPT-5.4), delivering top-tier CyberGym performance at significantly lower cost.
→ MAI-Cyber-1-Flash announcement
3. Why This Matters
Project Perception represents Microsoft’s clearest move yet from “AI that assists” (Security Copilot) to “AI that acts” under human oversight. Early adopters should evaluate it for vulnerability management playbooks first, then expand to threat-intel driven investigations.
Takeaway for defenders:
If you already have Defender XDR, log into the portal today and explore the new Perception experience. Start with low-risk playbooks and keep human approval gates enabled.
