What is VPN?
VPN is an acronym which stands for Virtual Private Network and is used to describe Wide Area Network (WAN) connections which are secure, private, and which cross the Internet instead of using expensive leased circuits.
What does VPN do?
 | Allows the Internet to be used to support secured network connections between separate offices or between individuals and their offices. VPN circuits can be established across dial-up connections but most commonly VPN's use broadband Internet connections to tie together offices into a single network entity. |
| The connections are extremely inexpensive and they can be secured with 168-bit 3DES encryption as well as authentication. You know your data is secured. |
| VPN's radically cut the cost of connecting offices...as opposed to a $1200/month leased circuit to connect an office in OKC to an office in Tulsa, why not spend $150/month at each location to have a circuit which is even more secure? |
How does VPN work?
The VPN implementation which DVITS utilizes is an industry-standard protocol called IPSEC which acts as kind of encrypted "package" for data travelling between locations. This "package" acts to protect the data from unauthorized users.
An IPSEC VPN creates a VPN tunnel through the Internet between locations. This tunnel is established as an encrypted circuit. In most of our applications VPN firewalls are used to establish the high-security tunnel. In this way nothing notable must be done on any client or server machines.
| Relatively inexpensive and easy to administer once the VPN's are established |
| Practically no administration is required |
| The connections create nearly no overhead on servers or workstations on your network because there is nothing for them to encrypt |
| VPN connections are very inexpensive compared to leased lines and are even more secure. All you need at your locations are broadband Internet connections with fixed IP addresses. |
