SpiderOak Zero Trust Data Access is a platform that provides zero-trust security for defense and commercial operations. The platform offers development tools for building applications with zero-trust security capabilities, enabling secure message delivery, data exchange, and access control between applications, machines, and sensors without requiring additional network security controls. The platform implements a zero-trust architecture that does not trust any single user or server within the security infrastructure. It provides role-based access control with full attribution and enforces access controls through decentralized implementation. The system uses zero-trust encryption combined with advanced segmentation to enable data usage across any environment and device. SpiderOak Zero Trust Data Access secures data exchange over any network through zero-trust authentication, authorization, and segmentation embedded into data and applications. The platform includes user and device management capabilities with full encryption. It has been deployed in defense applications including satellite communications for low-Earth orbit networks and GPS satellite authentication systems. The platform is available in both open source and commercial editions. The commercial Team & Enterprise edition includes technical support, premium features with custom APIs, verified builds, certified compiler, enrollment and assignment user interface, mission management dashboard, certifications such as FIPS, professional consulting services, and customized training. The open source version provides core features with community support through documentation, forums, and bug fixes.
