Virtual
Private Network (VPN)
Virtual
Private Networks are used for secure data communications from one
location to another utilizing the public Internet as the medium.
Virtual Private Networks (VPN) can be used for secure data communications
for traveling users, branch/remote offices or business partner communications.

Virtual Private
Networks use encryption/decryption to secure the data while traveling
over a public network (Internet). If the data is captured while
in transit the encryption provides extreme difficulty in reading
this data. Thus making the data captured virtually useless.
Virtual Private
Networks can be accomplished by three basic methods: Hardware, Software,
and SSL VPN.
Hardware
- Virtual Private Networks also provide basic levels of access to
the VPN network. Most Hardware VPN devices provide a basic Level
2 firewall to block unwanted intruders
from breaking the network while also performing the VPN encryption
functionality. Hardware devices are much easier/faster to use and
support.
Software
- Virtual Private Networks that utilize software to perform the
encryption is ideal for single PCs or Home users. The more sophisticated
software programs also protect the PC similar to a firewall (Check
Point Secure Client). Other software providers just provide
VPN encryption but do not protect the PC.
SSL
VPNs- Clientless VPN remote access (NO SOFTWARE NEEDED).
This solution solves three major issues currently faced with all
other VPNs: 1) Maintain Security, 2) Cost Effective and 3) Easy
to Use. Generally, security, cost effective, and ease of use would
not be found in the same context when discussing VPN’s. Nokia
Secure Access Server (.pdf link) offers and delivers all three.
Choosing the
correct Virtual Private Network is a very complex process. This
process is very much determined on budget, firewall and network
complexities. VPNs are extremely difficult to install and manage
with any type of reliability, security and flexibility built into
the design. While most VPN vendors claim this is an easy process
our years of experience have proven otherwise. We have built many
secure and stable VPNs for our customers.
