Virtual Private Network

A VPN (Virtual Private Network) offers a secure and reliable way to share information across public computer networks, such as the internet.  Data is encrypted before being passed over the public network hence the term ‘virtual private network’.

 

There are different types of VPNs, including:

 

Site-to-site: connects a network consisting of many users/devices to another similar network

Client-to-site:   connects a single user device to a network, e.g.  home user accessing HQ

SSL VPN: enables the user to securely access resources on a network through a web browser

 

Features/Benefits

For an organisation looking to provide a secured network infrastructure for its user base, a VPN offers two main advantages over alternative technologies: cost savings, and network scalability.

 

A VPN can save an organisation money in several situations:

 

• Eliminating the need for expensive long-distance leased lines

• Reducing long-distance telephone charges

• Offloading support costs
