VPN - Virtual Private Network - It helps in expanding a private network through a public network. Initially, VPNs were introduced and used among large enterprises, defence organization, banking companies etc. to keep their data secure. A VPN created a pathway through which people working in large organizations could access the data they want, remotely, in a secured manner. Times have changed and with it the popularity of VPN too! These days VPNs are so widely available that they are used by almost every one of us.
Benefits of using a VPN:-
1.) Anonymity - In the age we are living being anonymous on the internet comes as an urgency from time to time. When your Internet traffic routed through your ISP(Internet Service Provider), they can monitor everything that you do online. Not only do they monitor, but they track user’s behaviour with the intention of selling their personal data to various advertisers and third-party service providers.
2.) Security - VPN helps you in accessing a data more securely, it does so with the help of Cryptography. In Cryptography, the data is encrypted from the sender’s end and then it gets decrypted with the help of a unique key on the receivers end.
3.) Restricted Data Access - You can access data that is restricted in your country or even continent.
4.) Geolocation Testing - It is a process of testing where you evaluate a website through different GeoIPs.
5.) You can maintain a remote access to private data among your team or colleagues.
How does it work?
Once you connect to the Internet, your ISP(Internet Service Provider) receives the request to help you redirect to your intended website.
VPN redirects your Internet traffic through a remote VPN server, this way hiding your IP address and encrypting all of the information that is sent or received. With a VPN on, all the data you send and receive travels via an encrypted tunnel so that nobody can steal your private information or spy on your online activities.
