Cord3 is a data security platform that encrypts sensitive data using encryption keys that are inaccessible to administrators, users, and applications. It operates separately from applications, providing a centralized data security policy that applies consistently across systems rather than relying on application-level security implementations. The platform enforces access control at the point of every data request, verifying whether the requesting user — including privileged administrators — is authorized to access that data. This approach is designed to prevent both insider threats and external attackers who have compromised privileged credentials from accessing sensitive data. Cord3 manages encryption keys on behalf of users and applications through its own servers, which can be deployed on-premise, in the cloud, or in a hybrid configuration. It supports both structured and unstructured data and requires no endpoint or client software for deployment. The platform is positioned as a complement to existing solutions such as privileged access management (PAM) and user behavior analytics (UBA). Unlike data loss prevention (DLP) tools that require data classification before protection begins, Cord3 applies encryption immediately upon installation.
