Microsoft Security Copilot is an AI-driven security platform designed to empower security teams to detect, investigate, and respond to security incidents more efficiently. Launched a year ago, it has evolved to include AI agents that autonomously assist with critical areas such as phishing, data security, and identity management, addressing the increasing complexity and volume of cyberattacks.

The Phishing Triage Agent in Microsoft Security Copilot is designed to handle routine phishing alerts and cyberattacks. By accurately identifying real threats and false alarms, it allows human defenders to focus on more complex issues. This automation is crucial, especially given that Microsoft detected over 30 billion phishing emails targeting customers in 2024, which can overwhelm traditional security processes.

New features include AI security posture management that extends beyond Microsoft Azure to cover multiple cloud platforms, and enhanced detection for emerging AI threats. Microsoft Defender will provide visibility across various AI models and clouds, addressing risks such as indirect prompt injection attacks and sensitive data exposure, which are critical as organizations increasingly adopt generative AI.
