A connection is established between your system and the website you wish to access by your ISP whenever you wish to access a website. VPN, or Virtual Private Network, works in a similar way. It also connects you to the destination web address through a path. However, this path is essentially different than the one your ISP would take. But you might wonder why do you need to go to a website through a different path when your ISP does that for you all the time without a hitch? We will be addressing that question shortly and also discuss the many other services that VPNs provide to their users, making it absolutely vital for you to use them.
1. VPNs hide your geographical location from trackers
This is arguably the most important feature of VPNs. VPNs hide your geographical location and identity from hackers and tracking websites like Facebook. The fact that your IP address is masked by the IP address of the VPN server you are connected to makes it almost impossible to ascertain your location and identity using the IP address visible. VPNs also let you choose your preferred server from their list of servers. This allows you to bypass geo-restrictions and internet blockades that might be practised in your area. When you connect to a VPN, it shows you its list of available servers. When you connect to a server in a different location than your area, you will appear to be using the internet from that location. If you are looking to access geo-restricted services, this is an easy method for you to make it look like you are using their service from the US and gain access to any service you want.
2. VPNs encrypt internet traffic
As mentioned earlier, VPN connects you to the internet through a tunnel. This tunnel is encrypted, which means that all the data exchanged between the connection and your system is encrypted. This makes it difficult for hackers or attackers to gain knowledge of your sensitive data. Attackers use methods like a Man-in-the-Middle attack to intercept data packets and decipher them to find out what is contained within those data packets. Even government agencies monitor the web activity of their citizens. VPN thus maintain the confidentiality and integrity of your data by encrypting all incoming and outgoing traffic.
The features of VPN service discussed above are really necessary for people to keep their identity secret and surf the web safely. All VPN services focus on providing privacy and confidentiality to their users when they use the internet. In countries like China, where a lot of restrictions are placed on the internet activity of users, VPNs help people to use the internet as they like. They also prevent government agencies from monitoring your web activity. All in all, in this age where privacy is so disvalued and underrated, VPNs are one of the few services that still try to help people exercise their universal Right to Online Privacy. They are also really easy to set up as most VPN providers offer detailed setup guides to their customers.
