Google Cloud Shielded VMs, see #3 and #4 below.

Summary:  services can authorize device/VM connection if the managed device/VM can prove through certificates and/or runtime cryptographic measurements that it is executing a known-good stack of hardware, firmware and software.  This can be done on a resource basis, e.g. access to a sensitive spreadsheet or document, within a "zero trust" or "software defined perimeter" network architecture.

(small advertisement:  OpenXT uses OpenEmbedded in an open-source platform for device assurance and runtime attestation, so that vendors and customers can make geographic and industry-specific choices for device keys, certificates and trust hierarchies.  Some features, e.g. measured boot, are being unbundled so they can be used by other projects.  We are working towards an upstream-first, CI workflow with OE meta-virtualization and Xen)
