The primary reason to use an SSL VPN product is to prevent unauthorized parties from eavesdropping on network communications and extracting or modifying sensitive data. SSL VPNs enable users to access restricted network resources remotely via a secure and authenticated pathway by encrypting all network traffic and making it look as if the user is on the local network, regardless of geographic location. By providing a higher level of compatibility with client platforms and configurations for remote networks and firewalls, SSL VPNs provide more reliable connections.īecause the SSL protocol itself has been deprecated by the Internet Engineering Task Force (IETF) and replaced by TLS, SSL VPNs running on modern browsers now use TLS to encrypt and authenticate data transmitted across the VPN.

SSL VPNs are important because they provide an E2EE mechanism for client internet sessions and because they can be easily implemented without the need for specialized client software other than a modern web browser. An SSL VPN 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.Įnterprises use SSL VPNs to enable remote users to securely access organizational resources, as well as to secure the internet sessions of users who are accessing the internet from outside the enterprise. SSL VPNs enable devices with an internet connection to establish a secure remote access VPN connection with a web browser. What is an SSL VPN (Secure Sockets Layer virtual private network)?Īn SSL VPN 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.
