iTop
What it is
iTop is a free, open-source IT service management and configuration management database solution. It manages configuration items and their relationships alongside requests, incidents, problems, changes, and service catalogs. Teams can modify and extend its CMDB model to represent technical, functional, and organizational components. Its service catalog connects CMDB data with processes for qualifying tickets, calculating SLAs, and supporting service reporting. Change and problem workflows include ITIL-compatible change management, monitoring, recovery plans, escalation, and links between incidents and problems. The synchronization engine can federate multiple sources, with OCS Inventory, VMware, and Microsoft Graph named as examples. Integration options include a REST API, webhooks, case exchange, and collectors for external systems such as Microsoft Azure, vSphere, and Ansible. Security controls include role-based permissions, SSO through SAML, OAuth, OpenID, or CAS, multifactor authentication, brute-force protection, and data silos. The Community plan is free of charge and not limited. Subscription offers are available as SaaS and on-premise; the iTop 3.3.0 release notes specify PHP 8.2 as the minimum version.
