SSL and TLS in a nutshell.

“Handshake” between browser and server: Certificates such as SSL and TLS are used to encrypt the data exchange between the web browser and web server and thus protect it from unauthorized access. It therefore benefits visitors and website operators alike.

Even though the term "SSL (Secure Socket Layer)" has generally been used for the certificates, we at INWX now use the successor technology TLS (Transport Layer Security).

SSL or TLS — is that really necessary for you?

Whether it is in an online shop, in a forum or on a website with a login area — sensitive data is involved everywhere. As soon as this data is entered, stored or transmitted online in any form, it needs to be protected! This is the only way to avoid possible legal consequences.

SSL/TLS is the best solution. For example, the modern HTTPS security standard (with the famous lock icon in the address bar) is only possible with SSL/TLS. To keep your visitors and your own data safe, you should buy a TLS certificate. It will also significantly improve your search engine rankings.

Which certificate is right for you? 

The type of certification you should choose depends on the nature of your site. At INWX we offer 3 individual levels:

Validation takes place in relation to the domain: The Certification Authority (CA) verifies that you actually have technical access to your domain. This is the simplest form of certification — we recommend it for private sites, blogs and for new companies and online shops. It is often necessary to have a certificate from the Commercial Register Department A (HRA).
