Microsoft has unveiled a new artificial intelligence-powered cybersecurity platform, Project Perception, that combines specialized security agents with a new cyber-focused AI model, MAI-Cyber-1-Flash, which the company says outperforms competing models including Mythos 5 while costing roughly half as much, according to Bank Info Security. The platform uses Microsoft's multi-model security agent harness (MDASH) and three types of AI agents: "red" agents that identify attack paths, "blue" agents that investigate and prioritize threats, and "green" agents that harden environments and remediate weaknesses. Microsoft also introduced MAI-Cyber-1-Flash, a security-focused foundation model trained on decades of Microsoft's security data, which scored 95.95% on the CyberGym evaluation, outperforming GPT-5.5 Cyber (85.6%) and Mythos 5 (83.8%). Microsoft AI CEO Mustafa Suleyman said the new model delivers stronger cybersecurity performance than competing offerings and costs about half as much, though the company did not disclose pricing.
