SSL certificate - What is it?

You've probably noticed that a small lock is usually displayed next to the website domain in the URL bar of your browser. Find out what this is all about and why this little symbol is so important in this blog article!

SSL certificate: What is it and why is it so important?

"SSL" is the abbreviation for "Server Sockets Layer" and describes an encryption protocol for secure data transmission on the internet. It ensures that the data traffic between the users of a website and the website itself is encrypted and that no third party can intercept and read the information in between. If no SSL certificate is stored on the website, the data is transmitted in plain text. This opens the door to phishing attacks and the tapping of sensitive data, for example - especially in public Wi-Fi networks.

In addition, the SSL certificate has the function of validating the website owner and confirming their identity. It therefore confirms to users that they are really on the website of the specified provider

You can tell that you are surfing the web securely by the small lock and "https" displayed next to the website domain. In some cases, you will also be warned directly by the browser if you want to visit a website that does not have an SSL certificate.

What types of SSL certificates are there?

First of all, it is important to know that there are many different SSL certificates, which differ mainly in their level of validation. There are certificates that only check the existence of the domain - these are often free of charge and are sufficient for simple websites. At the same time, there are other certificates that also check the address of the web provider, for example - these cost a little more and are more suitable for e-commerce websites. With such certificates, you usually also have a higher level of insurance cover should the certificate not be "cracked".

Where can I get an SSL certificate?

There are various certificate authorities ("CA" for short), which differ in their verification procedures and prices. These certificate authorities check your details and then issue the corresponding certificate. Hosting providers usually work with a fixed CA. However, if you operate the website via your own server, you can also choose a CA yourself. The certificate must then be installed on the web server after it has been issued so that the encryption is activated.

Here are some trusted certification authorities that we recommend:

• Let's Encrypt
• Digicert
• GeoTrust

The certification is usually limited to a certain period of time, but is renewed automatically and at regular intervals.

It protects the data of your website users and makes your website trustworthy. In addition, an SSL certificate usually offers a certain level of insurance protection.
