SSL and TLS

What is SSL?

SSL (Secure Sockets Layer) is a technology that was developed to encrypt the data that is exchanged between your web browser and a website. SSL ensures that sensitive information such as passwords, credit card details or personal information is protected and cannot be read by third parties. SSL has long been the standard for secure connections on the Internet.  

What is TLS?

TLS (Transport Layer Security) is the further development of SSL and offers even better protection for your data. While SSL is now obsolete, TLS is now used as a more secure and modern encryption method. When someone refers to “SSL”, they are usually referring to TLS, as the two terms are often used interchangeably. The important thing to remember is that TLS, like SSL, ensures that the connection between your website and visitors is secure and encrypted.  

How can I see whether my website is secured with SSL/TLS?

You can easily check whether your website is secure:  

• Lock icon: A small lock symbol appears in the address bar of your browser if the connection is secure.  

• “https” in the URL: Instead of “http”, the address of your website begins with “https”. The “s” stands for “secure” and shows that the connection is encrypted.  

• Check SSL certificate: You can also click on the lock icon to display information about your website's SSL/TLS certificate. There you can see whether the certificate is valid and which certification authority issued it.  

By ensuring that your website is secured with SSL/TLS, you not only protect your visitors' data, but also increase trust in your website. Many browsers mark websites without SSL/TLS as “insecure”, which can deter potential visitors.
