IT service management software handles incidents, requests, changes and problems, runs the service catalogue and keeps a configuration management database (CMDB) and asset inventory. IT departments use it to organise support, track what is deployed where, and show that processes are followed. Increasingly it also serves HR, facilities and legal teams. ServiceNow and Jira Service Management are widely known non-EU reference points.
An ITSM platform is a map of your organisation. The CMDB records servers, applications, dependencies, owners and versions, and tickets often mention vulnerabilities, outages and credentials pasted in by mistake. For an attacker this is reconnaissance, which is part of why the platform deserves the same protection as production systems under NIS2-type obligations. Over time, workflows, approval chains, automations and integrations with monitoring and identity make the platform deeply embedded, so a later move is as much a process project as a data migration.
When choosing a European option, check where ticket and CMDB data is stored, which vendor staff can see it, and how role-based access and audit logs are implemented. Ask for full export of tickets, assets and relationships in documented formats and APIs that support automated discovery and integration. Support for established service-management practices, a reasonable configuration effort and the option of self-hosting for sensitive environments are worth weighing.
