SSL VPN allows networks at different locations to be securely connected using a public network as a transport layer. SSL VPN gives users what they need without a full VPN implementation.

What is a VPN?
A VPN is a set of tools which allows networks at different locations to be securely connected using a public network as a transport layer. VPN uses cryptography to help combat eaves dropping and active attacks.

The VPN concept was to produce the virtual 'dedicated circuit', send it over the internet and make it secure using cryptography. SSL VPN however, is a web application that gives the users the services they need without a full VPN implementation.

SSL VPN implementation
Secure Ssocket Layer VPN is designed to be light on management which is perfect for network administrators to use alongside IPSec. It can be implemented into a network to help control emails, transactions, and information crossing the network.

Clientless solutions
Aventail Corporation is one of the market leaders in the development of clientless SSL VPN appliances. They have created the only solution available that provides highly secure, anywhere access to corporate resources, file shares, and applications from all types of devices. This makes it the most powerful and easiest-to-use SSL VPN on the market.

Summary
What seems to be clear is that the security process is based on simple principles and is very effective. However due to the fact that the development of hardware VPN devices is in its infancy, their setup seems to be beyond the average computer user. This means that hiring the services of a professional network administrator is advisable to guide you in the selection and setup of the right device for your business. Failing this, most SSL VPN companies offer a support service and will be able to supply all the relevant information.
