Technologies:  VPN Technologies

Virtual private networks (VPNs) are a common method of providing economical and effective remote access into an organization’s network.  Several different types of VPNs exist, and while VPNs offer a number of advantages there can also be significant disadvantages.

There are different types of VPNs:

• Remote access VPNs
• Site-to-site VPNs
• Application-specific VPNs

In addition, there are multiple VPN protocols available:

• IP Security (IPSec)
• Point-to-Point Tunneling Protocol (PPTP)
• Layer 2 Tunneling Protocol (L2TP) over IPSec
• Secure Sockets Layer (SSL)

As you can see, the number of combinations between these types of VPNs and VPN protocols can quickly become overwhelming.  Software-based VPN solutions, or VPN appliance, such as from companies like Array Networks?  Add in VPN solutions that require a client vs. clientless VPN implementations, end-point security assessment, and fine-grained access control, and VPNs suddenly are a lot more complicated.
