Edgeless Systems Constellation vs enclaive Buckypaper CVMs: 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. Enterprise and mid-market teams handling regulated workloads or processing sensitive data in untrusted cloud environments should pick enclaive Buckypaper CVMs for hardware-enforced isolation that doesn't require rebuilding infrastructure. The 3% CPU overhead is legitimate; most confidential computing approaches tax performance far more heavily, and EU datacenter deployment with ISO 27001 and C5 compliance removes friction for regulated industries. Skip this if your threat model is insider threats alone or you lack the technical depth to manage hardware-backed enclaves; Buckypaper requires operators who understand confidential execution environments, not just VM operators.
