Project Context As part of the national CaRE program (Cybersecurity, Acceleration and Resilience of Institutions), a group of five hospitals wanted to assess the robustness of their Active Directory (AD). The challenge was critical: protecting the hospital information system from internal and external threats while ensuring the continuity of patient care. Objectives The main objective was to test the security and resilience of the AD in order to: Identify exploitable vulnerabilities, including internal ones Assess the exposure level of the information system Provide concrete and prioritized recommendations to strengthen hospital cybersecurity Mission Duration A short but intensive mission, including a technical audit, intrusion scenarios, and an operational debrief. Implementation Agaetis deployed a rigorous audit methodology: PTES framework: Adoption of international standards to structure the mission Grey-box penetration testing: Combination of manual and automated tests across the network Simulated intrusion scenarios: Realistic situations to measure AD exposure Comprehensive and actionable report: Vulnerabilities classified by severity with prioritized recommendations Results Achieved Enhanced security: Clear identification of vulnerabilities with an associated remediation plan Cybersecurity awareness: Increased internal understanding of AD-related risks Decision-making support: Practical recommendations to prioritize corrective actions Regulatory compliance: Alignment with cybersecurity requirements in the healthcare sector Key Success Factors Strong technical expertise from Agaetis in AD environments and sensitive IT systems Methodology tailored to hospital environments Educational and immediately actionable deliverables Supportive approach focused on guidance and knowledge transfer And You?
