I wrote the original RFE so I'll provide this piece. Docs: https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere/8-0/vsphere-security/securing-virtual-machines-with-virtual-trusted-platform-module/vtpm-overview.html Has this quote: "A virtual Trusted Platform Module (vTPM) is a software-based representation of a physical Trusted Platform Module 2.0 chip." So, emulated version 2.0. Can't find anything about CRB vs TIS but I believe CRB is default for TPM 2.0 devices in general so I took that to be implied. I lack a setup to confirm at the moment but I can scrounge one up if you'd like Thanks, Cole
