Zero Networks announced the Kubernetes Access Matrix, a real time visual map that exposes every allowed and denied rule inside Kubernetes clusters.

The new capability enables security and DevOps teams to see, understand, and control Kubernetes access at scale, closing "understanding what is going on inside K8s” gaps that leave organizations exposed to lateral movement and operational risk.

The Kubernetes Access Matrix transforms complex Kubernetes Network Policies into a single, intuitive matrix view that shows what can talk to what across namespaces, applications, and workloads. By translating policy logic into clear visual outcomes, it creates a shared source of truth for both security and DevOps teams.

The Access Matrix provides a real time understanding of how far an attacker could move once inside a cluster, exposing implicit trust relationships and over-permissive access paths before they are exploited. Instead of relying solely on detection after compromise, teams can proactively reduce blast radius, protect critical services, and maintain uptime even during a security event. This shifts Kubernetes security from reactive response to proactive resilience, aligning operational maturity with the reality of near-instant attack attempts.

Upon onboarding, the Access Matrix automatically discovers existing Kubernetes Network Policies with no manual configuration required. Within minutes, teams can visualize namespace to namespace, application to application, workload to workload, and egress access. Color coded indicators clearly distinguish full access, partial access, explicit deny, and areas with no defined policy. Users can drill into any connection to view the exact policies, labels, workloads, and ports governing that flow.

More than a visualization tool, the Kubernetes Access Matrix becomes the foundation for enforceable guardrails across clusters. Security teams can define boundaries and validate them directly in the matrix, while DevOps teams maintain flexibility within approved limits. Policy changes can be validated before deployment, preventing risky access paths from reaching production.

The Kubernetes Access Matrix is available immediately as part of the Zero Networks platform.
