If you’re wondering which process is used to protect transmitted data in a VPN, the answer is encryption. Encryption is a key part of a VPN’s security protocol and ensures that your data is safe from prying eyes.

VPN, or Virtual Private Network, is a technology used to protect transmitted data between two devices in a private network. The data is encrypted before it is sent, and then decrypted after it arrives at its destination. This ensures that the data cannot be intercepted and read by anyone who does not have the proper encryption key.
Data encryption is the most common and effective way to protect data transmitted over a VPN. Data encryption scrambles your data so that it is unreadable by anyone who does not have the decryption key. This makes it very difficult for anyone intercepting your data to read or make sense of it.
Data authentication is the process of verifying the accuracy and integrity of data that is transmitted in a VPN. This process is used to protect the data from being modified or tampered with during transit. Data authentication can be done using a variety of methods, including digital signatures, hashing, and encryption.
Data compression is a process used to reduce the size of data files for storage or transmission. This is done by removing unnecessary or redundant data from the file. Data compression can be either lossless or lossy. Lossless compression ensures that all original data can be recovered when the file is decompressed, while lossy compression discards some data in order to achieve a higher level of compression.
Encapsulation and encryption are the two main processes used to protect transmitted data in a VPN. Encapsulation hides the data within other data, while encryption scrambles the data so that it is unreadable without a key. Both processes are important for ensuring the security of VPN transmissions.
