DigiCert has extended its partnership with Google Cloud to provide independent cryptographic attestation for confidential computing workloads. Using PKI-based signatures and certificates, DigiCert acts as a neutral third-party root of trust, verifying that workloads running in memory on confidential VMs are genuinely encrypted — removing reliance on cloud providers to self-certify security. The move addresses growing demand driven by AI model training with proprietary data and digital sovereignty requirements. An IDC survey found 75% of organizations are adopting confidential computing, with data integrity, regulatory compliance, and workload security as top drivers. DigiCert plans to extend similar attestation partnerships to other cloud providers.
