CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams running SGX-enabled Kubernetes clusters who need to orchestrate confidential computing workloads will find MarbleRun's single unified attestation statement more operationally useful than managing per-enclave attestation chains. The manifest-based policy definition means you're writing JSON deployment specs instead of wrestling with SDK integrations across Gramine, EGo, and Occlum. Skip this if you're not already committed to Intel SGX hardware; MarbleRun assumes confidential computing is your architectural constraint, not your starting question.
Mid-market and enterprise teams managing sensitive data across Google Workspace or Microsoft 365 need Virtru Private Keystore if regulatory compliance requires encryption keys to stay in your own infrastructure, not the vendor's. Docker-based deployment across public cloud, private cloud, or HSM means you control key residency without architectural rework, and CJIS, HIPAA, CMMC 2.0, and ITAR support validates that claim. Skip this if your team lacks the ops capacity to run a separate key management appliance or if you need key rotation and lifecycle management at scale; Virtru prioritizes key custody over key operations.
