SSL Protocol

What is SSL protocol?

SSL, or Secure Sockets Layer, is a security protocol which encrypts data transmitted between a user’s browser and a website.

 

Why is SSL important in payments?

It protects sensitive information such as card details and personal data during online transactions, preventing interception by unauthorised parties.

 

How can you tell if a site uses SSL?

Websites using SSL display “https” in the URL and often show a padlock icon in the browser.

 

Is SSL still used today?

SSL has largely been replaced by TLS, a more secure version, though the term SSL is still commonly used.

 

What happens if a site does not use SSL?

Data transmitted may be exposed, increasing the risk of fraud and reducing customer trust.
