A VPN Utilizes following techniques to safeguard your data:

⮚      Hiding IP Address:

IP Address (Internet Protocol Address) is a unique address provided to every device for the digital identification. Whenever a user gets on the internet and starts surfing, the IP Address of the device is used by the ISPs and Websites to identify the user sending and receiving information. So far so good.

The problem arises when a hacker tries to steal your IP Address which is a sensitive piece of information and can be used to harm you in many possible ways.

A VPN utilizes different servers to hide your IP Address. When a user connects to the internet with a VPN, the information, before going over the internet, goes to the server and then the server sends the same information to the website. This way, the website only gets the IP address of the Server and not of the user.

⮚      Encrypting:

The data that you send over the internet, be it a Message, an Image, your bank account details, or anything possible, is sent in the form Data Packets. Though you now have your IP Address hidden, the data that you send and receive can still fall in wrong hands.

Hence, VPN Encryption is used to protect the users from such threats. A VPN encrypts the data on data packets into codes which are only decryptable by the website or receiver and not a hacker in-between.

The level of VPN encryption depends upon the VPN protocol that a service provider uses in order to encrypt the data. The stronger the VPN encryption and secure, the harder the hit on your Internet speed.

⮚      VPN Tunnel:

To add another level of security, VPNs create a secure private tunnel between the sender and receiver that is separate from the route followed by all the other information over the internet. Creating a VPN Tunnel is like creating your own highway that is only open for your vehicle. This way, the information runs hidden and unnoticed by the hackers trying to steal the information. Whether a VPN utilizes a private Tunnel or not, depends upon the VPN Protocol it uses.
