osTicket

osTicket at a glance

osTicket is a long-established open-source support-ticketing system, widely used by SMBs to manage customer support requests. osTicket ships regular releases plus security fixes; as a web application handling customer communications and often integrated with email, hardening and timely updates matter.

For admins updates run through the documented procedure and include database changes — back up the database and attachments first, and keep the underlying PHP and database supported. osTicket has had security advisories, so apply security releases promptly. Keep the staff/admin panel off the open internet behind authentication, and secure the mail integration (fetching and sending) it relies on. The customer-facing portal accepts untrusted input and attachments — a surface to keep patched. After upgrading, verify login, ticket creation, and mail flow in and out. Track the version and its support status; patchletter surfaces new osTicket releases so security fixes aren't missed.
