Defense at AI speed: Microsoft’s new multi-model agentic security system tops leading industry benchmark

Microsoft announced MDASH (a multi-model agentic scanning harness that uses over 100 specialized AI agents working together to find security vulnerabilities), which discovered 16 new vulnerabilities in Windows, including four critical remote code execution flaws (where attackers can run commands on systems they don't own). MDASH achieved an 88.45% score on a public cybersecurity benchmark, outperforming other systems, and is currently available only through a limited private preview program.
