Zero Networks Microsegmentation is a network security platform that automates the implementation of microsegmentation to prevent lateral movement and contain security breaches. The solution deploys in approximately one hour and automatically discovers all network assets without requiring manual tagging or labeling. The platform operates through a 30-day learning period during which it monitors and analyzes all network connections to create deterministic firewall rules and security policies. After this learning phase, the system automatically applies microsegmentation across all assets both on-premises and in cloud environments. The solution creates firewall boundaries around individual assets with privileged ports closed by default. It enforces least privilege access controls and integrates multi-factor authentication at the network layer for just-in-time access. The platform supports both managed and unmanaged devices, including IoT and OT environments, using agentless technology. Zero Networks provides visibility into network activities and asset inventories, enabling organizations to control both inbound and outbound traffic through centralized policy enforcement. The system monitors North-South and East-West traffic patterns and automatically adapts security policies based on network behavior. The platform addresses compliance requirements by demonstrating granular access controls and network segmentation. It restricts logon rights, closes privileged ports, and applies internet traffic controls to minimize attack surfaces and prevent unauthorized access during penetration tests and security assessments.
