Implementing Zero Trust Architecture with NetFoundry

This white paper outlines the implementation of a Zero Trust architecture in alignment with NIST SP 800-207 using NetFoundry's Identity-First Connectivity. It begins by identifying the limitations of traditional IP-based networking, which relies on network reachability and exposes organizations to increased risks of cyber breaches. The paper details how NetFoundry's programmable Zero Trust Overlay Network (ZTON) enhances security by embedding protections directly into the application layer and abstracting the network infrastructure. Key components of the architecture include the Policy Engine, Policy Administrator, and Policy Enforcement Point, which work together to continuously evaluate trust and enforce access policies based on cryptographic identities. The document also discusses critical security outcomes, such as micro-segmentation, continuous evaluation of access rights, and deep visibility for auditing. Additionally, it presents a case study of a major defense contractor that successfully transitioned to this architecture, highlighting the operational benefits and enhanced security posture achieved through the implementation of NetFoundry's solutions.
