Joomla at a glance

Joomla is a widely used open-source CMS, powering many websites between the simplicity of basic tools and the complexity of enterprise platforms. Joomla ships regular releases plus coordinated security fixes; as an internet-facing CMS, prompt patching is essential.

For admins the security releases are the rhythm — apply them promptly, since Joomla sites are heavily targeted, and past critical flaws were exploited quickly. Keep to a supported Joomla version and track its end-of-life. Extensions (components, modules, plugins, templates) are the dominant attack surface — keep them minimal, current and from reputable sources, and remove what you don't use. Updates run database changes — back up first and test on staging. Harden logins (strong credentials, two-factor) and keep the underlying PHP supported. After updating, verify the site and extensions. Patchletter surfaces new Joomla releases and security updates so fixes aren't missed.
