Intel Phases Out SGX, Shifts to TDX for Next-Gen Server Security

Intel announced that Xeon Diamond Rapids, launching in mid-2027, will be the final CPU family to support Software Guard Extensions (SGX). The focus will shift entirely to Trust Domain Extensions (TDX), which offer VM-level isolation. Microsoft has set a deadline of October 31, 2027, to retire SGX enclaves in Azure. The transition emphasizes operational simplicity for cloud workloads while requiring careful migration planning for existing SGX users.
