Project Perception is a coordinated agentic defense system. MDASH is a specialized code-security analysis engine. A simple, concise explanation would be: Copilot assists humans analyzing vast amount of security sources, MDASH discovers software vulnerabilities at machine speed level, and Project Perception coordinates security agents to determine what’s exploitable before an attacker does. Additional insights The newly updated documentation adds a clearer operating model for Project Perception: a continuous cycle to perceive risk, reason across security context, and act with human oversight. It also describes the underlying cyber stack and the role of the purpose-built MAI-Cyber-1-Flash model. Perceive, reason, and act Perceive: Continuously identify emerging risk across endpoints, identities, clouds, applications, and broader security signals. Reason: Apply threat intelligence, organizational context, and security signals to determine which risks are meaningful. Act: Help defenders move from findings to protective action faster, while retaining human judgment and approval for high-impact decisions. The new cyber stack Layer Role in Project Perception Field positioning cue Signals and sensors Provide visibility across endpoints, identities, clouds, applications, data, and AI. Start with the breadth of the digital estate. Security context Connect signals, threat intelligence, and organizational knowledge so agents can reason with operational context. Context turns raw signals into relevant understanding. Models Use a multi-model approach, including specialized cybersecurity reasoning. Select the right model for the task rather than relying on one model. Harness Orchestrate models and agents with the tools and controls required for reliable operation. The harness coordinates workflow, evaluation, and control. Agents Apply Red, Blue, and Green roles across discovery, investigation, response, remediation, and hardening. Agents are specialized roles working as one defense team. Actuators Translate decisions into real-world protective effects, not only recommendations. Actions remain governed and subject to the appropriate oversight. MAI-Cyber-1-Flash and the MDASH relationship MAI-Cyber-1-Flash is a Microsoft purpose-built cybersecurity model optimized for software vulnerability analysis. It operates as one model within the multi-model MDASH system, supporting selected stages of vulnerability discovery and analysis. MAI-Cyber-1-Flash provides specialized reasoning, while MDASH coordinates multiple models and scanning agents, and Project Perception connects those findings to broader defense workflows. Governance and human control Human oversight remains part of the operating model, especially for critical or high-impact actions. Agent activity should be positioned as governed, logged, auditable, and aligned to least-privilege access. Project Perception is designed to inherit enterprise security, governance, privacy, and compliance foundations rather than operate outside them. Appendix A: Project Perception Agent Roles and Relationship to Security Copilot and MDASH Understanding the Red, Blue, and Green Agents Project Perception is built around a coordinated virtual team of specialized AI agents. Just as human security organizations employ Red Teams, Blue Teams, and Security Engineering functions, Project Perception introduces AI agents that perform analogous activities at machine speed while maintaining human oversight for critical decisions. Red Agents Red Agents are responsible for identifying weaknesses before attackers can exploit them. Typical activities: Discover attack paths Identify exposed assets Detect privilege escalation opportunities Analyze risky configurations Correlate exposures across systems Surface previously unknown attack opportunities Business value: Red Agents help organizations move from reactive security to proactive exposure management by continuously searching for conditions that could enable compromise. Blue Agents Blue Agents investigate and validate risk. Once a potential exposure or threat is identified, Blue Agents determine whether it represents a meaningful security concern. Typical activities: Analyze alerts and incidents Correlate telemetry Validate exploitability Assess likelihood of attack Prioritize findings Evaluate business impact Generate investigative conclusions Business value: Blue Agents reduce alert fatigue and help security teams focus on the threats and vulnerabilities that present the highest operational risk. Green Agents Green Agents focus on remediation and hardening. After a risk has been identified and validated, Green Agents help eliminate or reduce that risk. Typical activities: Recommend fixes Validate remediation strategies Propose configuration changes Reduce attack surface Improve security posture Coordinate hardening activities Track remediation progress Business value: Green Agents help close the gap between identifying a problem and fixing it, accelerating risk reduction across the environment.
