NetFoundry provides zero trust networking solutions built on OpenZiti, an open source zero trust software platform that the company's founders invented and maintain. The company's Identity-First Connectivity technology enables secure communications between distributed workloads across networks without requiring VPNs, open inbound ports, or firewall configuration changes. The company serves two primary markets. Software and IoT solution providers use NetFoundry to establish secure communications with workloads deployed at customer sites. Enterprises use the platform to secure access to APIs and agentic AI services, implement hybrid IT/OT segmentation, and enable identity-based microsegmentation. NetFoundry recently unveiled an OT security platform with embedded zero trust capabilities designed for critical infrastructure environments. The platform addresses connectivity security for operational technology environments, industrial IoT deployments, and edge devices in smart city applications. The company has partnered with organizations like FreeWave Technologies and Keyfactor to deliver integrated IIoT connectivity security services. The technology eliminates traditional network security approaches by implementing deny-by-default security principles at the identity level for users, devices, and applications. Customers use NetFoundry to replace site-to-site VPNs and firewall-based access controls with identity-based microsegmentation. The platform supports Infrastructure-as-Code automation for customer connectivity deployments.
