A new multi-model agentic security system, built with over 100 specialized agents across both frontier and custom models, has been unveiled by Satya Nadella. The system is designed to identify exploitable bugs with high efficiency, achieving top results on the CyberGym benchmark. According to Nadella, it was deployed ahead of Patch Tuesday and contributed to the discovery and remediation of 16 vulnerabilities, demonstrating a proactive step in strengthening U.S. cyber defenses.
Nadella has made similar moves in AI-enabled enterprise security, previously announcing Agent 365 for AI-driven identity and security management. He also rolled out GPT 5.5 Instant for M365 Copilot, bringing faster and more accurate results to enterprise users. Both initiatives reflect a sustained focus on integrating advanced AI tools into Microsoft’s product suite.
