What Is a VPN?
A Virtual Private Network, known as a VPN, is a privacy boosting tool. It encrypts the data and makes it invisible to anyone who's spying on your activities. The changing security landscape results in an increased number of cyber-attacks that risk your online security and privacy. This gives rise to the use of a VPN. A VPN disguises your identity and makes you completely anonymous while you surf the web. The VPN software uses an encryption process for safeguarding your data. It hides your real IP address, your internet traffic, and boosts your online security.
It hides your IP address by routing your traffic to a secure tunnel. Encryption is an efficient process that makes your data traffic unreadable. Thus, your ISPs or any other third-party can't track you or your online activities. Using a VPN has become a necessity in today's world. It gives you complete online freedom without exposing your real identity. Other than freedom, a VPN is beneficial for the following reasons :
• Access the geographically restricted content
• Avoid tracking
• Bypass strict censorships
• Download torrents
• Protection against ISPs
• Play online games
• Remain anonymous
• Use free Wi-Fi networks without worrying about online security.
How Does a VPN Work?
A VPN hides your real IP address by creating an encrypted channel between the local server and the VPN server. It assigns you a new IP address and substitutes with your original one. All your internet traffic passes through that IP address to the VPN server. Your ISP or any other third-party agent won't see what you're doing. Thus, in this way, VPN works. From the VPN server, your data or request to access any website or service is being made. It seems like your device's location made the request.
But in reality, it is the VPN server that makes the request. Every VPN provider offers a list of servers to the users. You have to select the nearest one for a safe and secure browsing experience. Once you connect with the VPN server, this will happen to your data:
• The VPN software installed on your device encrypts your data. The data passes through the encrypted tunnel to the VPN server.
• The VPN server is present in some other location. It decrypts the data sent by your device.
• The private server sends the data to the internet and receives the answer.
• The reply is again encrypted by the VPN server and sent back to the local server.
• Now the clients' server decrypts the data so you can understand it.
A VPN works like a filter that changes all your data to an unreadable form. No one can ever know what it is all about. In this way, you can surf the web anonymously.
