Private and Virtual Private Networks Explained By Derek Rogers At Isnare.com Ezine Articles

If you need private networks or virtual private networks to connect multiple sites, many companies will allow you to do this. You can give people who work at home or at other remote offices a private network and you can even give this to customers, suppliers and partners where you need to.

What do you need? Do you need Ethernet connectivity, leased lines, SDSL, or ADSL?
These solutions exist today and you can even get the bandwidth and security you need, too. Today's solutions are top speed, very reliable and perhaps most importantly, secure. With a TLS VPN-based service, if you need to, you can route traffic economically and securely instead of having to build a dedicated private network.

You also will usually get firewall access and you can change bandwidth options as you go so as to change your network needs instead of having to choose the most expensive option first. You have a bespoke capability and multiple service options, multiple access options and usually, 24 hour, seven days a week monitoring and help desk, all for an affordable price.

Virtual private networks explained

With the expansion from local to global logistics for a lot of businesses, companies have suddenly had to think about how to keep sometimes disparate and very remote locations connected. In addition, those connections have to be very fast and secure. Leased lines over a wide area network (WAN) are one option, of course, but this can get expensive and often goes up in cost the further apart locations are.

Enter virtual private networks. Virtual private networks are private networks that use a public network (usually the Internet) to connect its remote users together so that they can communicate in real-time. Instead of using something like a leased line, a "virtual" connection is sent through the Internet from the company's private network and basically connects with the remote site where the employee, other office, etc is. It's just basically a way for very distant colleagues who need to work together to have the ability to do so, almost as if they were sitting side by side in the same office.

It's also very secure, so that no proprietary company information or other information that needs to be kept private is exposed or otherwise put at risk.
Below are two types of virtual private networks are explained:

Remote access VPN

The first is remote access VPN. This type of connection is necessary when secure, encrypted but mobile connections are needed between, for example, salespeople in the field (remote users) and accompanies private network. Other remote users connect to the company's private network with a third-party service provider.

Site-to site-VPN

The second type of VPN is called a site-to-site VPN. With this, instead of having remote and sometimes mobile users connected, a company can establish permanent connections with two or more remote but "intercompany" sites together with a private network.

Alternatively, another type of site-to-site VPN occurs where you want "intercompany" connections established, such as with a particular company and a major client.

Check with your provider to see if establishing a VPN might be necessary for you.
