Zammad

Zammad at a glance

Zammad is a popular open-source helpdesk and ticketing system, common in SMBs and support teams, especially in Europe. Zammad ships regular releases plus security fixes; as a web application holding customer communications and often integrated with mail, hardening and timely updates matter.

For admins updates run through the documented procedure (package or Docker) and include database migrations — back up the database and attachments first, and mind the required Elasticsearch and database versions. Zammad has had security advisories, so apply security releases promptly. Keep it off the open internet behind authentication and TLS, and secure the mail and API integrations it uses. After upgrading, verify login, ticketing, search and mail flow. The many channels (email, chat, integrations) widen the input surface — keep them configured deliberately. Track the version and its support window; patchletter surfaces new Zammad releases so security fixes aren't missed.
