Detailed explanation-1: -Transport Layer Security (TLS) encrypts data sent over the Internet to ensure that eavesdroppers and hackers are unable to see what you transmit which is particularly useful for private and sensitive information such as passwords, credit card numbers, and personal correspondence.
Detailed explanation-2: -When TLS-encrypted emails are carried through protected email servers-that is, between both client and recipient servers-eavesdropping on the email’s content is virtually impossible. Just as SSL secures web connections through HTTPS, TLS adds another layer of protection for email transport.
Detailed explanation-3: -The Transport Layer Security (TLS) protocol adds a layer of security on top of the TCP/IP transport protocols. TLS uses both symmetric encryption and public key encryption for securely sending private data, and adds additional security features, such as authentication and message tampering detection.
