Secure VPN Connection to your home or branch office.
Have you ever been sitting at home and wondering, did I transmit the order today? Did I remember to do the end of
day processing? How were my sales today? If only I could find out without having to get dressed and go in to the
With a VPN solution from D Squared Computer Consulting you can. A VPN (Virtual Private Network) gives you the ability
to securely connect back to your business from the comfort of your home or hotel room or anywhere you can get an
Internet connection. If you are travelling with your business or personal laptop and using an IPSEC fat client and remote
desktop you can connect back to your business and check these things and more. It is like you are sitting at your desk,
you will control your office computer remotely and securely. An SSL VPN system with a VPN concentrator will allow you to
connect securely from any computer without a client. Determining which solution is right for you is as simple as discussing
it with our Systems Engineer and to find out how and where you will need to connect from.

The following is from TechNewsWorld:
Virtual private networks (VPNs) are common in enterprise settings as a way to connect remote users and branch offices
securely to the business network. VPN’s extend a business's reach to support worldwide locations.
The same usefulness is gaining the attention of small and medium-sized businesses (SMBs). Smaller companies are
finding VPNs cheaper to operate than more costly dedicated T1 lines.
However, SMB players have been slow to fully adopt VPN connectivity over more traditional Web site access and
cumbersome security hardware and software combinations. The VPN trend, though, is clearly trickling down to smaller
"Enterprise adopted VPN first. Its use is starting to grow on the SMB level. It is now used consistently even in three- or
four-people home-based offices," James Mabie, territory manager for SMB at Check Point, told TechNewsWorld.
A virtual private network is a dedicated communications network that only certain users can access. A VPN creates a
tunnel through another network. This, in effect, controls traffic to and from the network, rendering it a private rather than
a public access portal.
Despite the access limitations a VPN provides, VPNs are not strictly security measures. While one common application is
securing communications through the public Internet, VPNs do not need explicit security features such as authentication
or content encryption.
"Encrypted connections is a feature of VPNs, not really security. VPN is a remote access operation," Dirk Morris, founder
and chief technical officer of Web services firm Untangle, told TechNewsWorld.
The networking experts at his company argue this point all the time, he said. The popular notion is that the only reason
to use VPN is for security; however, other network security solutions are available without using a VPN.
"A VPN is used more for productivity than for security. It combines a firewall with the tunneling capabilities," said Mabie.
VPNs, for example, can be used to separate the traffic of different user communities over an underlying network with
strong security features.
Other users of VPNs have a few office locations and want all branches connected to one location, he explained.
Especially on the SMB level, a VPN can enhance the connectivity of a company's workers to multiple sites, added Morris. In
this regard, SMB adopters of VPNs find the tunneling features a more cost-effective option than leasing T1 lines to
connect multiple sites.
From a business application viewpoint, VPN technology is just one more communication tool. That may make VPNs just as
valuable to SMBs as they are to larger corporations.
"The main reason a small business would use a VPN system is for remote staff access to information on servers inside the
corporate firewall," Lance Geeck, manager of IT for financial technology company Kettley, told TechNewsWorld.
This can include IT personnel who are on-call for IT problems during non-business hours, home office workers and
salespeople who are on the road, he added.
The perception that VPN services are the domain of big businesses rather than SMB users is all wrong, agreed Joe
Faranetta, director of product marketing for AT&T Enterprise Networking. SMB adopters have the same circumstances that
drive enterprise firms to use a VPN.
"If you step back and consider what a VPN really is, you find that companies of all sizes have been using VPNs since the
1980s with Frame Relay. The explosion of IP and its ubiquity and economy have expanded the capability and made single-
user remote access much more common, but this is clearly not just a big business play," Faranetta told TechNewsWorld.
In fact, any business that has a need for linking together various workflow systems can use a VPN for better productivity,
he explained. This includes inventory, point of sale and human resources tasks.
Tunneling from extranets at other companies or enabling workers to access company information remotely are all uses of
a VPN, regardless of a company's size. Users in big or small firms include traveling salespeople, managers who work from
home and more, he detailed.
Adding a VPN to an SMB firm's networking operation should have a very minimal impact on the budget. Rather than cost,
the real decisions involve whether to rely on an in-house IT guru or subscribe to a VPN provider.
"The cost varies depending upon need but can be as small as a couple of hundred dollars on the low end to thousands
for larger multiprotocol label switching (MPLS) VPNs," Faranetta said.
Most VPN configurations require a level of expertise that often is not found in the SMB workforce. The setup process is a
bit more involved than taking a router out of the box and cabling office computers to it.
"There is also a maintenance upkeep. The VPN may not always be working," said Morris. Maintenance tasks would require
an IT person on site or quick access to a third-party provider.
Related to the initial purchase and setup costs of a VPN is the issue of support staff. Does running a VPN in an SMB
environment require additional human resources in terms of in-house expertise? In a word, no. An SMB should not have
to hire more people to keep a VPN up and running.
Contracting with an IT service is the best bet, according to Kettley's Geeck. For most users VPN works without much
maintenance or monitoring. Setup is the biggest expense.
"It doesn't make sense to hire for just this. Kettley has a full-time IT professional, and we spend very little time -- less
than 2 percent -- on VPN issues," Geeck explained.
If in-house technical support does not already exist, an SMB can obtain a VPN solution completely by outsourcing.
"So it doesn't need to take up any internal resources. Because it can be outsourced completely, a VPN solution doesn't
require any additional people," AT&T's Faranetta said.
Networking pros are seeing a trend towards VPN use among SMB firms.
"The use of VPN in the SMB space is not as widespread as it should be, given the benefits. It is not well deployed yet, but
it is starting to catch on," observed Untangle's Morris.
