Overview
- Microsoft announced the new offerings on Monday, July 27, 2026, introducing MAI-Cyber-1-Flash as a compact security model, MDASH as a 100+ agent vulnerability‑hunting harness, and Project Perception as an agentic red/blue/green team platform.
- The company reported that MDASH with MAI-Cyber-1-Flash delivered about 96% recall on the CyberGym benchmark and that the lighter model handles roughly 90% of routine tasks while routing the hardest 10% to GPT‑5.4 to save compute costs.
- Microsoft says the MDASH system found 16 previously unknown Windows vulnerabilities that were patched in May 2026, including four critical remote code execution bugs, showing the tools have already been used in real remediation work.
- MDASH is available in a limited private preview through Microsoft Defender and Security Exposure Management, and Project Perception is scheduled to enter public preview on August 3, 2026.
- Microsoft emphasizes safety controls and third‑party assessment including Red Team testing, tenant isolation, sandboxing, and role‑based access, but the headline CyberGym score was self‑reported and public independent verification was pending at publication time.
