Microsoft boosts security with AI, automation

Microsoft has unveiled a sweeping set of security enhancements across its product ecosystem, with a significant focus on artificial intelligence and automation, according to SecurityWeek.

The announcements, made at the Ignite 2025 conference, are largely centered on the Microsoft Defender suite, introducing proactive features like Predictive Shielding for automatic attack disruption and a natural language Threat Hunting Agent. A major theme is the extension of protection to new frontiers, including AI agents, with new tools like Agent ID in Entra to prevent agent sprawl and unified security management for AI in Defender.

The company is also deepening integrations, launching third-party attack disruption via Sentinel for services like AWS and Okta, and connecting Defender for Cloud with GitHub Advanced Security. Furthermore, Security Copilot is being significantly expanded with 12 new dedicated agents for core security products and 30 from partners, aiming to automate tasks for SOC, identity, and IT teams.

These updates, most available in preview, represent a strategic push to offer a more interconnected, AI-driven, and proactive security fabric for modern enterprise environments grappling with cloud and AI complexities.
