A TLS certificate is a digital authentication credential issued by a trusted authority called Certificate Authority (CA). It allows users of a website to verify the identity of the website and enables encrypted communication between them and the website.

A TLS certificate contains information such as the website’s domain name and its public key, allowing a web browser (or any client) to confirm that it’s connecting to the legitimate server and establish a secure, private channel.

In essence, this certificate ensures data exchanged over the Internet cannot be read or altered by unauthorized parties, thanks to cryptography.

TLS Certificates at Scalingo

At Scalingo, we use a CA named Let’s Encrypt to automatically generate a certificate for every custom domain added to the platform.
For further information about this feature, please read our dedicated documentation.

We also support TLS certificates generated and signed by other Certificate Authorities, so you can provide your own custom certificate if you prefer.
