CM, a Belgian health insurer, migrated its Atlassian environment from Data Center to Cloud, with integration into Azure Entra ID as a requirement. The technical integration through Atlassian Guard was easy to set up. The real challenge was operational: deciding in which platform licences, groups and permissions are managed. ACA Group listed the decisions to make, guided and advised CM, and made sure all stakeholders were informed and aligned. The result: licences managed in Azure Entra ID, permissions in Atlassian groups, and an enterprise-grade identity and security solution with clearly defined roles and responsibilities.
