Xiid Terniion is a Zero Trust network access solution that uses SealedTunnel technology to eliminate attack surfaces by establishing outbound-only connections. The product removes the need for open ports, public IP addresses, and scannable endpoints, making infrastructure unreachable to external attackers. The solution creates process-to-process tunnels at the application level, providing isolated connection paths that prevent lateral movement within networks. Each connection is protected with triple-layer, quantum-resistant encryption designed to defend against man-in-the-middle attacks and harvest-now-decrypt-later threats. Terniion operates as an overlay on existing applications, services, and devices without requiring network reconfiguration or infrastructure replacement. The product supports on-premises, cloud-native, and hybrid environments, including containerized and distributed architectures. The solution has received Authority to Operate certification from the U.S. Department of Defense and has been validated by the Air Force Research Laboratory for infrastructure invisibility. It is designed to help organizations meet compliance requirements by eliminating exposure risks through encryption and reduced attack surface. The product is deployed in government systems and enterprise environments for securing remote desktop protocol connections, system management, EV charging infrastructure, cloud services, and medical data pipelines.
