A Virtual Private Network connects a private network and a public network over the internet. There are a number of systems that enable you to create networks using the internet as the medium for transporting data. They use encryption and other security mechanisms to ensure no one see the information which is being exchanged.
Clients use a private VPN service also known as a VPN tunnel, to protect their identity and also prevent others from sniffing internet activity. Most of the Companies and Organizations use VPN service to communicate with their clients confidentially over a public network and also send their voice, video or data. This is an excellent option for remote workers who have global offices and partners to share their data in a private manner.
VPN was not the first technology to make these remote connections. Several years ago, the most common way to connect computers between global or multiple offices was by using a leased line. Leased lines or ISDN (Integrated Services Digital Network) are private network connections in which a telecommunication company could lease to its customers. These leased lines are reliable, secure but too expensive with the cost increases as the distance. But now-a-days internet service providers provide more reliable services than leased lines. Even most of the companies have replaced leased lines with new technologies.
A VPN can save organization money in several situations:
A number of popular VPN services keep data logs and new services are springing up all the time. If you are planning to use a VPN for privacy reasons, then these are the key questions you might keep in mind:
1. What types of data are encrypted? All of the data transmitted or received including your email, instant messages etc. are as well.
2. Does any new software to be installed for to set up VPN? There is no need of any software to set up your VPN Connection. SSL is working on SSL protocol which has 2048 bits encryption and you need to install open VPN software which will be sent to you with the package.
3. Does third parties able to see my data? When connected with VPN servers, a third-party can only see the data transmission but they cannot tell what the data is.
So, keep the above points in mind before choosing the best VPN service.
