Cybersecurity startup Zero Networks launched a virtualization tool with added guardrails for Kubernetes clusters.

The Kubernetes Access Matrix promises a visual map to untangle Kubernetes network policies by translating policy logic into clear visual outcomes. This offers real time projections on the potential scale of an in-cluster attack, helping security teams to proactively reduce blast radius while maintaining critical services and uptime.

Zero also claimed the tool instantly detects Kubernetes policies on the network upon onboarding, with visualization offered across namespaces, applications, workloads, and egress access. Color coded indicators are used to distinguish full access, partial access, explicit deny, and areas with no defined policy.

“Kubernetes doesn’t fail security teams because it is inherently insecure,” Zero Networks CEO Benny Lakunishok explained. “It fails because access becomes opaque at scale. When you cannot clearly see who can talk to what, you cannot control blast radius. The Kubernetes Access Matrix makes every connection visible and understandable in seconds, so organizations can reduce risk before an attacker exploits it.”

Zero earlier this month launched its Network Map 2.0, promising a real-time living enterprise matrix to replace more static, point-in-time visualizations.

Last summer saw Zero Networks raise $55 million in Series C funding, topping up its total coffers to more than $100 million.

The Tel Aviv-based firm said the funding would increase its go-to-market investments in North America, Europe, the Middle East and Africa (EMEA), and Asia-Pacific, with Juniper Networks and Palo Alto Networks veteran Tony Hadzima appointed shortly after as its VP of sales for EMEA and Latin America.
