Are you looking for the best VPN software? We have listed the top options that you may use for your project.
VPN is the acronym for “Virtual Private Network”. Basically, VPN is a service that protects your privacy online by protecting your internet connection. With VPN, it is possible to encrypt your traffic to ensure that no one can track your online activity.
VPNs help use public Wi-Fi connection securely, access geo-restricted content and maintain online privacy. By hiding your IP address, VPN protects your digital identity.
When you use VPN, all the internet traffic travels through encrypted tunnels, ensuring privacy from governments, internet service providers and hackers. A few of the many benefits of a VPN include the following:
- IP address change
- Privacy protection
- Security
- Accessibility to blocked websites
If you are critical of your digital identity, then VPN is a must for you. Now that we know the basics of VPN let us see how it actually works.
How Does A VPN Work?
Firstly, when you access the internet using a VPN service, your device gets connected to a VPN server. Secondly, this server employs an encryption protocol that varies from one VPN service provider to another to send and receive data.
In the third stage, the VPN creates an encrypted tunnel on the internet for securely transferring data to and fro. To maintain the security of all the data packets, encapsulation is used to wrap it in an outer packet; which again is encrypted.
Lastly, a decryption process comes into play when the data reaches the server to remove the outer packet and give you the needed data.
It is basically how a standard VPN service works. However, depending on the VPN types, there can be a slight variation. Generally, VPNs fall under the following three primary types: Remote access VPN, Personal VPN and site-to-site VPN.
