# Secure the Connections to Your YouTrack Server

> **Note:**
> All procedures described in this section of the documentation are only applicable for YouTrack Server installations. Connections to instances hosted in YouTrack Cloud are secured by JetBrains.

There are several ways to set up an encrypted HTTPS connection with TLS (SSL) between your YouTrack Server installation and its clients.

* Use a third-party TLS-terminating reverse proxy server. For details, see [Reverse Proxy Configuration](reverse-proxy-configuration.html).

* Use built-in TLS for your YouTrack Server installation. You can configure YouTrack to run in HTTPS mode: * During installation or upgrade with assistance from the [Configuration Wizard](configure-server-tls-configuration-wizard.html). * By enabling HTTPS for an existing YouTrack Server installation [from the command line](configure-server-tls-from-command-line.html).

You can [switch from a third-party TLS-terminating proxy to the YouTrack built-in TLS and vice versa](switch-between-third-party-proxy-and-built-in-tls.html) at any time.

> **Note:**
> Secure connections to YouTrack Server installations must be configured to use TLS version 1.2 or later. Connections using older versions of the protocol are no longer supported.
