NCP's Next Generation Network Access Technology

SSL VPN – the alternative Remote Access technology to IPsec

SSL is the acronym for Secure Socket Layer. SSL is the acronym for Secure Socket Layer. Originally, this technology has been developed in order to allow encrypted communication between web browser and web server. SSL VPN is usually referred to in combination with remote access. The fundamental idea behind SSL VPN approaches was to simplify the remote access to Intranet environments and to avoid the need of installation of a VPN client at the end device. This, however, is not sufficient anymore since modern remote access to a company network is subject to various, individual requirements.

For this reason NCP offers three different access methods:

  • If you wish to exclusively access your company’s network web applications and data server through a web browser, it is best to use a browser based SSL VPN (Web Proxy). This method puts the fundamental idea behind SSL VPNs into practice - it eliminates the need to install additional software at the end device. NCP's Secure Enterprise VPN Server (SSL) isolates the internal web server from direct access from the Internet. Only after successful authentication at the SSL VPN gateway, the user is granted access to the gateway.
  • If you wish to access non-http-enabled applications and to use a SSL VPN tunnel to communicate with your company server within the company network, it is best to use a "Thin Client" SSL VPN. The thin client has to be installed at the end device and can be downloaded via a web browser. It uses NCP's Port Forwarding Technology to open ports, configured by the administrator. These local ports allow software to securely communicate with the designated server within the company network.  
  • If the goal is to have fully transparent network access to the central network, it is best to use NCP's PortableLAN Client. Similar to IPsec, it is mandatory that this VPN client software is installed on the end device. This client is the virtual connection which transmits the whole network traffic via the encrypted SSL connection, which in turn connects the remote computer to the company network.

NCP's Secure Enterprise VPN Server (SSL) offers connectivity, comprehensive security through endpoint security and individual access control. It supports strong authentication features such as one-time-password-tokens (OTP), text messages (text/SMS) or digital certificates. The software can be scaled according to actual needs and it can either be installed directly on the hardware, using the operating systems Linux or Windows, or as virtual machine.
