Email-driven ticketing for IT, support, and operations teams: Request Tracker turns every message sent to support@, helpdesk@, or security@ into a tracked ticket with an owner, a priority, a due date, and a complete audit trail. Staff reply to customers and comment privately to colleagues from the web interface or straight from their inbox, while requestors follow their own tickets in a self-service portal. Lifecycles built in a visual editor define custom statuses, transitions, and rights per queue, and scrips fire notifications or automated actions whenever a ticket changes. Service level agreements honor business hours, escalations trigger as deadlines approach, and scheduled tickets recreate recurring chores such as monthly patch windows. A transaction query builder, saved searches, charts, and drag-and-drop dashboards turn ticket history into reports that export to CSV or arrive by email on a schedule. Asset catalogs track laptops, licenses, and servers beside the tickets that mention them, and an Articles knowledge base feeds canned answers into replies. Time worked is logged per ticket with a My Week timesheet, approvals route sensitive requests to the right people, and PGP or S/MIME protects email in both directions. A REST2 API, a command-line client, and more than 400 extensions connect RT to the rest of your tooling.

Keep every ticket tied to the servers, applications, and contracts it affects with iTop, an IT service management platform that joins a configuration management database (CMDB) to a helpdesk. Agents work user requests, incidents, problems, known errors, and changes through ITIL-style life cycles, and SLA targets for time to own and time to resolve move a ticket to an escalated status when a deadline passes. The CMDB models infrastructure, virtualization, end-user devices, software, and business applications, and its impact analysis graph shows what a failing server would take down. A service catalog of services and subcategories, backed by customer and provider contracts, feeds a user portal where employees and customers submit requests from a mosaic, tree, or list, follow progress, add comments and attachments, and reopen resolved tickets. Administrators bulk-load inventory from CSV, run consistency audits to catch data-quality problems, synchronize records from external sources, and connect other tools through REST web services. Sign-in works with local accounts, LDAP, or CAS, with optional two-factor authentication through authenticator apps, email codes, or recovery codes, and the console offers dark, high-contrast, and color-blind-friendly themes.
