SSL VPN  represents a type of virtual private network and uses the Secure Sockets Layer protocol or the Transport Layer Security protocol. Some companies see SSL VPN as a cheaper, simpler way to provide remote access to corporate data. SSL VPN can  be use with any standard web browser. It doesn't require you to install any specialized software on the end user computer.

There are two major types of SSL VPN:

SSL Portal VPN. This type is called ‘Portal’ because it is one entrance that leads to many resources. This portal allows a single SSL connection to a website at the same time, while giving the end user secure access to multiple network services.

SSL Tunnel VPN. Tunnel access is provided through a tunnel running under SSL. Web browsers and  users have secure access to multiple network services, including applications and protocols that are not web-based.

Thanks to SSL VPN,  users have remote access to restricted network resources through a secure pathway by encrypting all network traffic. It makes it look like the user is always on a local network, no matter where they are located geographically.

Advantages of SSL VPN

One of the advantages of SSL VPN is that it uses TLS technology, which is implemented in modern web browsers. What that means is that there is no need to install specific client software.

Encrypted circuits provide a more sophisticated and secure connection than traditional VPN protocols.

Also, SSL VPN requires less maintenance and technical support than traditional VPN.

SSL VPN is very ease to use, it can be deployed with virtually any modern web browser.

Besides the advantages of SSL VPNs, there are also some security risks associated with this technology. Regardless of the improvements in security measures, SSL networks can still be susceptible to spreading malware, spyware, viruses, worms and Trojans.
