Have you ever thought of owning your own private network enabling you to be in constant touch with friends and business associates? Probably sounds difficult to do or even impractical to set up and run! But don’t worry, this isn’t some work of science fiction; the name of the game is VPN. This is a step-change technology which facilitates VoIP communication over the internet and ensures secure communication in a private network setting.
VPN stands for Virtual Private Network, a technology which forms a private gateway between two users enabling them to share data and also encompasses security firewalls to protect against data theft and intrusion attempts. VPNs work using strong encryption thereby ensuring means of safe communication curbing incidents of eavesdropping and hacking.
VPN is primarily used by the corporate sector and IT companies. Having confidential information posted on Internet could be inviting trouble; hence companies have adopted VPN technology to keep the flow of communication covert.
The method in which VPN technology functions is, that using routers, connection between two users in established. The router acts like a private gateway to facilitate the purpose. The flow of communication through the router is protected since this gateway is not accessible by any other person because the routs are encrypted and protected by firewall.
The setting up cost of VPN is expensive since routers have to be installed, but since it’s a one time cost with greater benefits companies don’t seem to mind it. However an individual consumer would surely hesitate to incur an expense of this magnitude.
It is being revealed that, Enterprise routers and VPN generated $8 billion globally in 2014. Security of content has been, an issue with VoIP communication for some time now, but VPN has proved to sustain VoIP too very well, hence the future of, both VoIP and VPN is bright.
