An SSL VPN offers versatility, ease of use and granular control for a range of users on a variety of computers, accessing resources from many locations. There are two major types of SSL VPNs:
SSL Portal VPN: This type of SSL VPN allows for a single SSL connection to a Web site so the end user can securely access multiple network services. The site is called a portal because it is one door (a single page) that leads to many other resources. The remote user accesses the SSL VPN gateway using any modern Web browser, identifies himself or herself to the gateway using an authentication method supported by the gateway and is then presented with a Web page that acts as the portal to the other services.
