UEFI DevCon: Secure and Scalable Firmware Updates via Capsules
2025-10-09 , Main

Presenter: Mohamad Saleh, Insyde & Sean Loe, Insyde

As firmware becomes an increasingly targeted layer in modern systems, Firmware Capsule Updates are emerging as a critical mechanism for maintaining platform integrity. Firmware Capsule Updates provide a secure, standardized mechanism for delivering critical updates across diverse platform components—from BIOS/UEFI and CPU Microcode to TPMs, storage devices, and advanced security technologies like Intel TDX and AMD SEV.
The presentation will highlight how capsule updates provide secure, authenticated, and rollback-protected delivery of firmware updates across diverse hardware, as well as how it is an essential firmware-level component for new technologies such as DMR (Dynamic Microcode Replacement). Attendees will gain insight into how capsule-based delivery simplifies platform maintenance and lifecycle management, enhances security posture, and integrates seamlessly with OS-level interfaces to support scalable and resilient infrastructure.
