CST VerdictBased on our analysis of core features, integrations, 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.
