Case Study: Eure-et-Loir Departmental Council achieves improved Active Directory resilience and reduced attack risk with Quest (Change Auditor & BloodHound Enterprise)

The Eure-et-Loir Departmental Council reduces the risks from attacks with solutions from Quest

The Eure‑et‑Loir Departmental Council, a French territorial authority of about 2,500 employees responsible for social services, roads and colleges, depends on Active Directory for core authentication and authorization. After an attack disabled their AD, the IT team restored services but found they had no early alerts and needed stronger cyber resilience against identity‑based threats.

Partnering with Quest, they deployed Change Auditor for real‑time monitoring, alerting and blocking of risky AD/Entra ID changes, and SpecterOps BloodHound Enterprise to visualize and remediate AD attack paths. Together these tools deliver instant alerts, prevent privilege‑escalation actions (for example, additions to Domain Admins), reveal and prioritize attack paths, and enable proactive remediation—significantly reducing detection and response times and closing critical security gaps.
