VPN (Virtual Private Network) is a network to which you connect from your pc, mobile device etc. To connect you usually use third party software such as OpenVPN which is easy to install and configure. Once connected to a VPN network your communication with the world goes through it and not through the usual network routes of your Internet service provider.
Multiple physical and logical networks
Essentially, a VPN is called virtual network because it may span over multiple physical and logical networks to form a single, restricted virtual network on top of them. Thanks to this abstract and virtual design, VPN users don’t have to be geographically limited to a single location but may spread anywhere with access to Internet. The need for such virtual networks is very high in today’s global world where companies and organization have offices in various geographical locations and users may be spread all over the world. The only way for such emote users to be integrated in the work process, i.e. to connect to internal resources, file shares, printers, etc, is through the use of VPN connectivity.
Furthermore, another strong feature of VPNs is their external connectivity. VPNs allow remote. Once you are connected to a VPN, you are able to access outside resources, such as external web sites, through the VPN gateway. VPN’s unmatched support for external connectivity and browsing is very useful to privacy and security. When you connect to sites and Internet resources through a VPN your actual location and identity remain hidden. There is no feasible way for anyone, from aggressive marketing companies to repressing governments, to follow your activity. To anyone trying to interfere with your privacy you will be just another anonymous VPN user who has no location, nor identity. This makes VPNs indispensable to anyone concerned with his privacy – from the average home user who refuses to be under marketing surveillance to human right fighters living in dictatorships.
The external connectivity of VPNs can be also used for accessing restricted sites. For example, when a government has blocked a site, such as in China, VPNs not only allow you to access such blocked sites but they also hide your identity, protecting you from complications with local authorities. In other cases, companies restrict the use of their sites and the features they offer only to users within certain geographical regions. VPNs allow to avoid any such usually unjustified restrictions and still get full access to geographically limited sites.
Except the fact that VPNs protect your identity, they are also of great value to your online security, especially when transmitting sensible information online. This is due to the fact that once you are connected to a VPN, all your traffic becomes encrypted and impossible to be read and understood. Thus, even if your communication is eavesdropped no one will be able to decipher what site you are connecting to, nor what information you are exchanging online. That’s why traffic encryption is essential when you make online payments and use credit cards or when you just have private communications with third parties. Thus, thanks to VPN’s encryption your sensible data will remain protected even if you are connected to insecure networks such as public Wifis.
All security and privacy features of the VPN technology make it a necessity in today’s age of increasingly insecure communications, security breaches and privacy crimes. Whether you are a human rights fighter or just sensible online user, VPNs is your only choice to protecting yourself and the people you are communicating with.
Once you are convinced that you need VPN, then you should carefully choose your VPN provider. There are three essential tips on choosing the best VPN provider for you. First is the ease of use of the software and its support. You’d definitely want to avoid complex, unreliable software which messes up your computer and takes you too much time to configure. Next, you should make sure your VPN provider supports strong encryption to protect your communication. Not all providers are able to offer such strong encryption because it requires more resources. Finally, ensure that your VPN provider has enough points of presence and gateways with fast connectivity, especially in geographic location you are interested. All of these requirements are perfectly satisfied by vpntunnel.com to ensure your excellent experience and protection.
