Über CHU de Caen
The University Hospital Centre of Caen (CHU de Caen) is a major healthcare facility in Normandy, fulfilling public service missions in patient care, medical education, and research. Its chu-caen.fr domain represents a critical component of its digital communication infrastructure, supporting internal exchanges between medical and administrative departments, as well as official correspondence with patients, healthcare partners, and public institutions.
As a healthcare establishment subject to strict regulatory obligations, CHU de Caen must ensure the authenticity and integrity of electronic communications. The risks of domain spoofing and email fraud pose significant threats to an organization handling sensitive health data and establishing trusted exchanges with third parties.
Implementing a robust DMARC policy on chu-caen.fr forms part of a comprehensive cybersecurity strategy aligned with the requirements of the NIS2 Directive and DORA Regulation, which impose enhanced data protection and business continuity measures on critical entities, including healthcare providers. DMARC complements SPF and DKIM by providing reporting and rejection mechanisms for unauthenticated emails, strengthening defenses against phishing, Business Email Compromise (BEC), and identity spoofing.
The DMARC Observatory at dmarc.com documents the evolution of CHU de Caen's email security posture, promoting transparency regarding authentication practices and supporting the establishment's regulatory compliance efforts.
