What Is A Vpn

  1. 1. VPN Service Providers, Lets Talk About Them…For those of you who know little to nothing about VPN servers, don’t worry this article wasintended for you. We will go over the basics of VPN servers and go over the various differentVPN service providers. We have asked ourselves, what is a VPN? According to Google, aVirtual Private Network (VPN) server is a network that uses a public telecommunicationinfrastructure and their technology such as the Internet, to provide remote offices or individual users with secure access to their organization’s network (Wikipedia). In simpler terms, VPN provides internet access to those in remote areas, possibly miles away from the provider. This is technically a type of Wide Area Network (WAN). This allows for computer to computer communications like the transferring of files, video conferencing, and the receiving and responding to emails. The benefit of having VPN service compared to dial-up or leased line connections is the general cost effectiveness in relation to the security of the network. Dial-up and leased lines can be expensive and require a physical connection from computer to computer through thetelephone lines. For remote access users, this can be a real hassle, being as telephone lines aren’tgiving connectivity to the entire world.So, what is a VPN service provider? In general, there are two varieties of VPN servers: Remote-access as mentioned earlier and site-to-site servers. Remote access servers provide connectivityto users that are isolated from the general network. For instance, companies will hire VPNservice providers to allow employees to connect to the business network while at home or out oftown. Site-to-site VPN servers provide connectivity between two already established networks.This also comes in handy to the business world, in that it allows further networking betweenallied companies, ensuring that communications are fast and efficient. There are other scenarioswhere one might need these VPN servers. Scientists performing research in remote countriesrequire secure VPN servers in order to send their files back home where they are much lesslikely to succumb to corruption. Another scenario would be anyone going on extended vacationand needs a secure network to transfer files and telecommunicate.A quick Google search using the keywords “VPN service providers,” or "whats a vpn" will openup pages of companies available for providing VPN service. When I performed the search, sevenseparate companies appeared organically on the first page alone; the results go back severalpages. A key factor to keep in mind is that a company’s reputation and guarantees are far moreimportant than how big they seem. When it comes to VPN servers other than those that areextreme remote-access, small business VPN servers can provide just as excellent service. On theother hand, remote access servers may need a larger network and staff of employees to ensureyou are provided with the ultimate connectivity. This may only apply to extreme cases. Ifsomeone needs remote VPN access to a small village in Nepal, it would be much harder toprovide excellent connectivity rather that remote access for your home.
