StackRox vs Plexicus Container Security: 2026 Comparison
StackRox is a commercial container security tool by StackRox. Plexicus Container Security is a commercial container security tool by Plexicus. Compare features, ratings, integrations, and community reviews side by side to find the best container security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Teams building containerized applications on tight budgets should evaluate Plexicus Container Security for its runtime threat detection and automated response capabilities, which catch post-deployment attacks that image scanning alone misses. The platform covers the full shift-left-to-runtime arc with hardcoded secrets detection, CVE scanning, Kubernetes policy enforcement, and continuous monitoring, mapping to NIST ID.RA and DE.CM functions most buyers actually need. Skip this if you're looking for a broader CNAPP that handles cloud infrastructure or VMs; Plexicus stays focused on containers and Kubernetes, which is exactly why smaller teams without dedicated platform security engineers will move faster with it.
