[What it means](https://koahost.com/glossary-tls/#section-1)[For hosting](https://koahost.com/glossary-tls/#section-2)[Who reads the data after decryption?](https://koahost.com/glossary-tls/#section-3)[Knowledge base](https://koahost.com/resources/)

## What it means

TLS can protect data in transit and authenticate a server name through a certificate system. It does not prevent an authenticated endpoint from reading the data it receives.

## For hosting

Use supported protocols, correct certificates and automated renewal with monitoring. HTTPS is necessary for many services but does not fix an insecure application.

## Who reads the data after decryption?

The endpoint terminating TLS can normally access plaintext. Review reverse proxies and external APIs as well as the browser-to-site connection.
