+ + ++ Open-source data-centric security for developers. OpenTDF delivers the + Trusted Data Format (TDF) specification, foundational services for key + management and access control, and SDKs — the building blocks to + cryptographically bind protection directly to your data, wherever it goes. +
+ ++ Explore the standard. Prototype custom applications. Build architectures + where security travels with the data, not the network. +
+ + ++ Firewalls, VPNs, and network policies protect the boundary — not the data. + The moment a file is shared, downloaded, or moved to a new environment, + those controls vanish. Access decisions remain at the perimeter, while the + data moves on without them. +
++ OpenTDF inverts this model. Policies travel with the data itself, so you can: +

++ This is data-centric security: protection that's embedded, not bolted on. +
+ + ++ Built on the proven NIST ABAC model for interoperability and compliance. OpenTDF + follows established standards for attribute-based access control, ensuring your data + protection strategy is future-proof and audit-ready. +
+ +- OpenTDF is an open source system for implementing data centric security. - It provides the basic services required to enable the definition, application, - and enforcement of attribute based policies using the Trust Data Format (TDF). - TDF is an open standard that enables you to cryptographically bind - attribute based access control (ABAC) policy to a data object so that - the policy travels with the data wherever it goes. -
-- OpenTDF builds upon a decade of experience at Virtru - protecting data objects at scale using the Trusted Data Format - for organizations of all sizes and across all industries. -
-- Today's cybersecurity landscape is increasingly adopting and requiring Zero Trust models and frameworks. - Zero Trust operates on the principle of "never trust, always verify," - ensuring that every access request is authenticated, authorized, and encrypted, - regardless of its origin. OpenTDF implements this model by providing an open-source framework, specification, and set of services - that prioritizes the protection and integrity of data at every stage. -
-- By integrating OpenTDF’s data security features with a Zero Trust architecture, - organizations can enforce strict access controls, ensure data is continuously monitored, - and maintain comprehensive visibility into data interactions. This synergy not only - minimizes the risk of data breaches but also fosters a secure environment where data - can be shared and utilized with confidence. Together, Zero Trust and OpenTDF empower businesses - to uphold the highest standards of data security in an interconnected world. -
-- In 2023, the OpenTDF team undertook a significant re-architecture - of the OpenTDF platform to enhance its extensibility and interoperability, - responding to the evolving needs of our diverse user base and the dynamic cybersecurity landscape. - See our {" "}Github Organization Page to navigate the new repositories. -
-- This comprehensive overhaul involved simplifying core service components, - adopting standardized policy schemas, and improving platform APIs and SDKs both in - developer experience and in capability. By focusing on extensibility, we have enabled - developers to customize and extend OpenTDF’s functionalities to suit specific use cases, - fostering innovation and adaptability. As we continue to advance, our focus remains on empowering the community with a secure, adaptable, - and interoperable platform that meets the highest standards of data protection and fosters collaborative innovation. -
-- Through the sponsorship of Virtru and its partners, the OpenTDF project has been - meeting the needs of customers across industries and use cases. Check out{" "} - - Virtru Data Security Platform - {" "} - for more. -
-- Virtru, the sponsor of the OpenTDF developer community, would love to hear from you! -
-- We're developers, too, and as we mature the project, we're curious what you're building, and what kind of problems you may be encountering or are trying to solve. -
