vSphere enables you to configure Virtual Intel® Software Guard Extensions (vSGX) for virtual machines. Using vSGX enables you to provide additional security to your workloads.
Some modern Intel CPUs implement a security extension called Intel® Software Guard Extensions (Intel® SGX). Intel SGX is a processor-specific technology for application developers who seek to protect select code and data from disclosure or modification. Intel SGX allows user-level code to define private regions of memory, called enclaves. The enclave contents are protected such that code running outside the enclave cannot access the enclave contents.
vSGX enables virtual machines to use Intel SGX technology if available on the hardware. To use vSGX, the ESXi host must be installed on an SGX-capable CPU and SGX must be enabled in the BIOS of the ESXi host. You can use the vSphere Client to enable SGX for a virtual machine.
