There are two types of people that seek out Virtual Private Network service and installation.  The first person knows that they are interested in VPN technology in order to securely connect their employees into the network remotely. This person is not interested in the technical details, they just would like to know a price and timeframe. If you fall into this category, please skip to the bottom of the page.

If you are a more technical user looking to find out the differences between the types of VPNs and solutions to implement them with, then you have clicked to the right page. There are a number of reasons companies purchase VPN solutions:

1. Remote dial-up network access for mobile users
2. Remote, temporary access for outside vendors or contractors
3. LAN-to-LAN access for branch-office connectivity
4. LAN-to-LAN access for permanent vendor access

Here is a short list of the VPN technologies available to implement these:

Best offerings:

• SSL VPN - this allows properly authenticated, clientless access for dial-up connectivity
• IPSec - best solution for LAN-to-LAN connectivity

Security challenged:

• PPTP - low bit encryption level, vulnerable to hacking
• Firewall holes - while you can allow remote access by just poking a hole through the firewall, this presents the greatest security risk.
