Weekly Security Roundup: Agentic AI, SOC Automation, Memory Safety
Security news this week features new AI-powered protections for cloud, endpoints, and collaboration, with a focus on governance and operational agility. Ignite 2025 delivered sessions and resources on secure agentic AI, confidential computing, automated SOC, and broad partnerships. Updates in memory-safe platform hardware, managed agent lifecycle, and practical incident response are supported by more tools for hardening devices, data, and drivers.
Advancements in Confidential Computing and Memory-Safe Platform Security
Extending last week’s progress in custom baselines and memory safety, Azure has now implemented deeper Intel Trusted Domain Extensions (TDX) in collaboration with Bosch and Intel, providing stronger isolation for high-assurance workloads. Microsoft continues to move system code to Rust for firmware and drivers, with new ecosystem support through windows-drivers-rs and Cargo WDK. Secure Core PC and enhanced DFCI control also get newly updated deployment tools for IT.
