Answer: A virtual private network (VPN) is an encrypted connection from a device to a network on the Internet. Encrypted connections help secure the transfer of sensitive information.
Method for VPN Ensure Communication Over Public Networks
VPN works by creating an encrypted connection between devices. Encryption is a method of encrypting data so that only authorized parties can understand it. It uses data that can be read and manipulated in a way that an attacker or anyone else who intercepts it can see. (VPNs typically use IPsec or SSL/TLS encryption protocols.) All devices connected to the VPN are provided with encryption keys, which are used to encode and decrypt all data sent between them. This process will add a small amount of latency to your network connection, which may reduce network traffic. The benefit of this encryption is that VPN connections remain private even though they span public network infrastructure.
VPN connection hides your online information and protects it from outside access. Unencrypted data is visible to any network user who wishes to view the data. When a VPN is used, hackers and cybercriminals cannot decrypt this information.
It provides secure encryption. Encryption key is required to read the data. Without this, it would take computers millions of years to crack the code when subjected to brute force attacks. With the help of a VPN, your online activities are hidden even from the community.
