Zero Networks has introduced its Kubernetes Access Matrix, a visual control layer intended to assist security and DevOps teams in comprehending and managing Kubernetes connectivity on a large scale. This additional feature immediately displays permitted and prohibited traffic paths within clusters, helping teams get a clearer picture of access relationships without the need for YAML parsing, manual configuration, or guesswork.
According to the company, Kubernetes security generally ends up disconnected as the implementation of network policy, which is a centralized security team’s responsibility, hands over to DevOps and developers. With an increasing number of clusters, the expansion of namespaces, labels, and various policies, it gets more difficult to figure out what is actually being enforced and what extent an attacker could move if a system is compromised. The Access Matrix aims to eliminate this visibility gap by converting complicated Kubernetes Network Policies into one single and very easy-to-read matrix, which depicts how namespaces, applications, and workloads interaction occurs.
“Kubernetes doesn’t fail security teams because it is inherently insecure,” said Benny Lakunishok, CEO at Zero Networks. “It fails because access becomes opaque at scale. When you cannot clearly see what 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. Built for InfoSec, SecOps, NetOps, and DevSecOps, it bridges the communication gap between groups to turn fragmented oversight into shared accountability.”

The launch comes as threat actors increasingly target new clusters within minutes of deployment. Research done by Zero Networks indicates that an attacker can scan an AKS cluster within 18 minutes of its creation and an EKS cluster within 28 minutes. Gartner has also pointed out that Kubernetes is being slowed by skills gaps and immature DevOps practices.
According to Zero Networks, the Access Matrix automatically detects existing policies shortly after onboarding and displays namespace-to-namespace, workload-to-workload, and egress flows with color-coded indicators for full access, partial access, explicit deny, and no policy. Teams can drill into each connection to see the exact policies, labels, workloads, and ports involved.
Beyond visibility, the tool is intended to serve as an enforcement foundation, allowing organizations to validate policy changes before deployment and reduce risky access paths before they reach production.
