Edgeless Systems Constellation vs Protopia Roundtrip Protection (SGT): Side-by-Side Comparison (2026)

Edgeless Systems Constellation: Confidential Kubernetes distro that runtime-encrypts cloud workloads. built by Edgeless Systems. Core capabilities include Runtime encryption of all workloads running inside the Kubernetes cluster, Shielding from cloud infrastructure and privileged third parties, Remote attestation to verify cluster integrity..

Protopia Roundtrip Protection (SGT): Eliminates plaintext LLM inference exposure via client-side data transformation. built by Protopia AI. Core capabilities include Stained Glass Transform (SGT): stochastic data transformation that converts prompts into a protected representation before leaving the client, End-to-end elimination of plaintext exposure across the full LLM inference lifecycle (prompt input to model output), Client-side private output key: only the authorized client can decrypt and read the full model response in plaintext..

Both serve the Confidential Computing market but differ in approach, feature depth, and target audience.
