SSL, also defined as "Secure Sockets Layer", ensures that data is encrypted during server and receiver communication. The most familiar use is to encrypt the communication between the server and the internet browser while the data exchange on the website is taking place. In this way, it hides data transfers so that they cannot be deciphered by third parties.
TLS, also known as "Transport Layer Security", is the security layer that encrypts the data between two communication applications, allowing it to be transmitted in a protected manner. TLS provides data confidentiality just like SSL. The aim is to securely transfer important data such as personal data, payment or login information.
TLS is considered a more advanced and secure version of the SSL protocol, also developed by Netscape.
