Edgeless Systems Constellation vs Edgeless Systems MarbleRun: Side-by-Side Comparison (2026)

Short answer

Enterprise security teams running sensitive workloads on public clouds will get the most from Edgeless Systems Constellation because it encrypts data in use at the Kubernetes layer, blocking privileged cloud admins and hypervisor operators from seeing your computations. Coverage of NIST PR.DS and PR.PS reflects that dual protection across data and platform layers. Skip this if your team lacks the infrastructure depth to manage a confidential computing distro or if you need runtime detection and response; Constellation assumes your threat model is about isolation, not visibility into lateral movement. 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.
