NetFoundry

The company began as a project within Tata Communications' 'Shape the Future' innovation program, which provided the necessary incubation and resources to develop the idea into a viable business. NetFoundry was later spun off as an independent subsidiary of Tata Communications in 2019 after reaching a $1 million annual recurring revenue milestone in less than a year. In April 2025, the company secured its first external funding, a $12 million Series A round led by SYN Ventures, to accelerate the adoption of its platform.

NetFoundry's business model is centered on providing a secure-by-design, software-based networking platform that operates on a Network-as-a-Service (NaaS) model. This allows clients to create secure, private networks over the public internet without depending on traditional hardware like firewalls or specific network circuits. Revenue is generated through this NaaS offering and by licensing its software for on-premises deployment. The company's core technology is built upon OpenZiti, an open-source zero trust software it created and maintains. This open-core model provides transparency while offering enterprise-grade features separately.

The platform enables users to embed zero-trust, software-defined networking directly into applications via SDKs, or deploy it across various endpoints using agents and containers. This creates application-specific networks, known as AppWANs or AppNets, which micro-segment traffic with end-to-end encryption and identity-based access controls. The service is delivered over a global fabric of over 100 points of presence managed by NetFoundry, ensuring high performance and reliability. Clients use a web-based console or APIs to manage their networks, providing a 'network-as-code' experience. This approach is designed to eliminate dependencies on underlying network infrastructure and simplify security operations.

NetFoundry serves a diverse client base, including enterprise IT, operational technology (OT), and Internet of Things (IoT) solution providers. It has a significant presence in sectors requiring high security, such as financial services, critical infrastructure, and government. Notable clients and partners include two of the top five Fortune 500 companies, eight of the top ten U.S. banks, and organizations like Microsoft, IBM, Oracle, and the U.S. military. The company's technology is often used in an OEM 'Intel-inside' model, where providers embed NetFoundry's secure networking into their own products and services.
