What is a VPN?

Virtual Private Networks provide a private tunnel through the Internet, but privacy does not equal security. Firewalls and VPN Gateways provide authentification of users and encryption for the data. For organizations to fully realise the benefits of a VPN, it must provide:

• Strong authentication of users and devices
• Confidentiality and privacy of information exchanged within the VPN
• Seamless security that is easy to deploy and has minimal impact on users
• Rapid and easy deployment for small and large numbers of users

What is a VPN?
A Virtual Private Network usually refers to a network in which some of the parts are connected using the public Internet, but the data sent across the Internet is encrypted, so the entire network is virtually private. A typical example would be a company network where there are two offices in different cities. Using the Internet the two offices merge their networks into one network, but encrypt traffic that uses the Internet link.
