The concept of SSL VPNs is very similar to the working of SSL certificates on the Internet. Except, instead of the browser and a web host, you can set up a local machine that connects with localhost using an SSL certificate for authentication.
This way, an SSL VPN gives individual users access to an organization's network, client-server applications, and internal network utilities and directories without the requirement for specialized software. It allows safe, secure communication for all types of devices over an encrypted connection, regardless of whether the network is accessed via the public Internet or another protected network.
