TLS (Transport Layer Security) makes it possible to visit websites via https instead of http. It ensures that all data traveling back and forth between your browser and the website is encrypted.
TLS is the successor to SSL (Secure Socket Layer). Different versions exist. The latest version is currently v1.3. The most commonly used version in production environments is v1.2.

Combell supports all versions of TLS
Combell supports all TLS versions so that your website works on all devices. We do this because many older browsers (usually on older mobile devices) are not compatible with TLS v1.2.
Possible issues with old TLS versions
The older TLS versions v1.0 and v1.1 are now 20 years old and can cause a limited security risk in some areas.
This creates a dilemma: do you prefer to stay on the safe side and only opt for the support of TLS v1.2? Or would you rather continue to support the older protocols, even if they pose a security risk?
Do I have to disable TLS v1.0 and v1.1?
Disabling TLS v1.0 and v1.1 will make your website or web-based service inaccessible on older devices – this is why support for TLS v1.0 and v1.1 is enabled by default. As long as your website is more informative than interactive, that’s fine.
If the customer has to enter sensitive data on your website, which is usually the case with websites of banks, hospitals, webshops etc., you may want to do this in a safe way and disable support for TLS v1.0 and v1.1 . Do you want to disable TLS v1.0 and v1.1? Request this via email@example.com. This is at the expense of visitors using older browsers, such as on an Android smartphone built before 2015.
