CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Edgeless Systems Constellation
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.
Mid-market and enterprise teams managing Kubernetes at scale should pick StackRox for its runtime enforcement capabilities, which actually stop attacks in progress rather than just flagging them. The platform covers critical NIST Detect and Respond functions (DE.CM, DE.AE, RS.AN) through continuous monitoring and incident analysis, and its hybrid deployment model means you can run it on-premises or in the cloud without rearchitecting. Skip this if you need a lightweight, agentless CNAPP or if your infrastructure is primarily serverless; StackRox demands Kubernetes maturity to justify its overhead.
