Edgeless Systems MarbleRun is a free key management tool by Edgeless Systems. ProvenRun ProvenHSM is a commercial key management tool by ProvenRun. Compare features, ratings, integrations, and community reviews side by side to find the best key management fit for your security stack.
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.
Enterprise and mid-market security teams handling high-volume cryptographic operations or managing qualified electronic signatures should pick ProvenRun ProvenHSM for its formally verified OS, the only HSM platform with CC EAL7 assurance underneath the key management layer. It hits FIPS 140-3 Level 3, sustains 10,000 ECDSA signatures per second, and ships post-quantum cryptography algorithms ready for 2030+ compliance, which matters if your PKI roadmap extends beyond RSA. Skip this if you need plug-and-play integration with legacy enterprise tools; ProvenHSM demands custom development work and technical depth from your team, and the 56-person vendor means you're betting on a smaller player than Thales or Fortanix for long-term support.
