How to use a VPN?

VPN can be used in many different ways. A typical situation is when a private network is accessible from a remote user through the Internet with the help of a remote access VPN connection. Another situation may be where a corporate network is connected to a remote office with the help of a persistent site by site or by VPN demand connection.

VPN can be applied in such situations to facilitate connectivity via the Internet or another public, private or intranet network. In some cases, the VPN connection can be implemented in an extranet for reliable communication with colleagues. The extranet operates as an intranet that can be shared securely with a specified business partner.

It will make use of advanced encryption techniques to ensure that personal information is not violated. VPN using state-of-the-art security procedures and tunneling protocols provide total security and privacy on the web.
