More Info
									    Virtual Private Networks are one of several
  services you may hire from your local internet
or networking services provider. In a nutshell, a
  Virtual Private Network uses an interlink that
     goes over a TCP/IP network (such as the
 Internet) that has several security and latency
   features enabled, such as direct routing and
 increased packet security. The earliest type of
      virtual private network has only recently
become virtual; the usual modality for handling
 networking in an office used to be a local area
network with either a client-server arrangement,
           or a peer-to-peer architecture.

 The primary benefits of a virtual private network are hard
authentication; it provides greater security and (with the appropriate
encryption and other security measures activated) can handle
military grade security requirements The secondary benefit is
generalized ease of administration; if a new software patch needs to
be pushed to all the desktop computers in an organization, a VPN
gives most of the benefits of a centralized networking infrastructure
while still working through commodity routers and networking gear
As this service has become more wide spread, many internet service
providers (ISPs) have become resellers (or primary sellers) of virtual
private networking solutions
 VPN solutions have become more important as constant connection
devices have grown smaller and more capable; it's no surprise that
the largest growth in the segment stems from people needing a
secure way for their Blackberries and other smart phones to connect
to their secure mail servers When looking for a VPN provider,
you're comparing them on two broad categories: Security (how up to
date they are on their security protocols, balanced by how easy they
are to use) and reliability A VPN that's down all the time isn't
providing you (or anyone vpn services else) a significant benefit
  Of these two, it's security that truly drives VPN adoption and use
Security requires that the underlying network be trusted, or that the
VPN enforce and verify that security mechanisms are in place; a
VPN that does the latter is much more intrusive than just using the
internet for email delivery
 Both of these security models require an authentication mechanism
before users can log onto the Virtual Network When touching on
security and uptime, remember that a VPN provider is basically
taking on the functions of what would otherwise be another two to
three IT staffers in your organization
 The Virtual Network Provider is charged with generating the
provided connection with security layers, and with maintaining that
access to all users This often gets merged with the task of
maintaining security updates for an entire organization's IT
infrastructure, and a VPN provider is often the first step towards
reducing the costs of an IT department by outsourcing it
  Before sourcing a VPN provider contract, do due diligence Look
seriously into the needs of your users; there will always be a subset
of users who need VPN access no matter where they are; the
likeliest candidates are remote field agents and telecommuters
working on secure parts of the company's process
But without knowing what you're doing on this, you have no real
metric for what will be charged
