Haltdos Remote Access Gateway is a type of virtual private network (VPN) that uses the Secure Sockets Layer (SSL) protocol -- or, more often, its successor, the Transport Layer Security (TLS) protocol -- in standard web browsers to provide secure, remote access VPN capability. It enables devices with an internet connection to establish a secure remote access VPN connection with a web browser. The Haltdos Remote Access Gateway connection uses end-to-end encryption (E2EE) to protect data transmitted between the endpoint device client software and the SSL VPN server through which the client connects securely to the internet.
