Case Study: Somfy achieves continuous Active Directory monitoring and rapid remediation with Tenable Networks (Tenable.ad)

How global manufacturer monitors and protects its Active Directory infrastructure

Somfy, a French global leader in building opening automation and connected-home solutions with operations in 58 countries and €1,257.1M revenue in 2020, needed to secure a complex Active Directory estate spanning multiple entities, a child domain and many administrators (including third-party admins). Protecting intellectual property, designs and customer data required a targeted assessment of the root domain; Tenable.ad’s initial analysis immediately revealed Indicators of Exposure such as AdminSDHolder, Root Permission and Kerberos Delegation issues, excessive administrator memberships and hidden attack paths.

Tenable.ad was deployed instant‑on to map AD topology, continuously monitor IoEs, and provide step‑by‑step remediation plus hands‑on workshops and dashboards for Somfy’s teams. As a result Somfy implemented an adequate delegation model, mitigated new admin‑introduced risks within a day, identified and fixed systems/jobs with wrong credentials, used brute‑force detection to locate misconfigurations, ensured newly joined machines fell under patching GPOs, reconfigured risky service accounts, and established ongoing compliance monitoring.
