Greymatter.io vs Romana: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
Greymatter.io is a commercial microsegmentation tool by Greymatter.io. Romana is a free microsegmentation tool. Compare features, ratings, integrations, and community reviews side by side to find the best microsegmentation fit for your security stack.
CST VerdictBased on our analysis of core features, here is our conclusion:
Kubernetes platform teams operating on-premises or in OpenStack environments should pick Romana for its topology-aware IPAM that enforces network policy without overlay complexity, eliminating a major source of troubleshooting overhead in multi-tenant clusters. The free pricing and 249 GitHub stars indicate active maintenance, and the native policy approach maps cleanly to NIST Govern functions around access control architecture. Skip this if you're cloud-locked on AWS or GCP; Romana's value evaporates when your infrastructure already handles IP management and you need tight vendor integration with cloud-native IAM.
