Basically,
a VPN is a private network that uses a public network
(usually the Internet) to connect remote sites or users together.
Instead of using a dedicated point-to-point connection, real-world
connection such as leased line, a VPN uses
"virtual" connections routed through the Internet from the
company's private network to the remote site or employee.
Through the use of
dedicated equipment and large-scale encryption, a company can
connect multiple fixed sites over a public network such as internet.
VPN's can be either.
- Intranet-based:
If the company has one or more remote locations that they wish
to join in a single private network, they can create an intranet
VPN to connect to LAN.
- Extranet-based:
When a company has a close relationship with another
company, they can build an extranet VPN that connects LAN
to LAN, and that allows all of the various companies to work in
a shared environment.

We design your VPN, we use several methods
for keeping your connection and data secure through setting up the
following.
-
Firewall- Firewall provides a strong
barrier between your private network and the internet
-
Encryption-This is the process of taking
all the data that one computer is sending to another and
encoding it into a form that only the other computer will be
able to decode, again we do provide the following encryption
methods Symmetric-key encryption and Public-key encryption.
-
IPSec- Internet Protocol Security
Protocol (IPSec) provides enhanced security features such as
better encryption algorithms and more comprehensive
authentication.
