Israeli cybersecurity startup Zero Networks Ltd. raised $55 million in new funding to expand its team and scale up go-to-market efforts worldwide. Zero Networks offers automated, agentless microsegmentation solutions that prevent lateral movement and block ransomware attacks. The company’s platform simplifies the implementation of zero-trust security by dynamically learning network behavior and enforcing least-privilege access controls without the need for manual configurations or additional agents. The company offers a Saas solution that learns network traffic and creates security policies that restrict user and machine access to only necessary assets. The platform also deploys multifactor authentication for access to sensitive protocols to stop hackers from moving laterally through an organization. Microsegmentation is core to the company’s offering. The platform creates secure micro-perimeters around every device on a network, including operational technology and internet of things devices. The platform ensures that only necessary network permissions are maintained by monitoring network traffic and applying deterministic rule creation, thereby reducing the risk of unauthorized access. Zero Networks also offers identity segmentation, which restricts admin and service account access strictly to operational needs. The approach prevents privileged account abuse by enforcing multifactor authentication and just-in-time access, to enhance an organization’s security posture against credential-based attacks.
