Über Caen
The City of Caen, a French territorial collectivity, manages the caen.fr email domain—a strategic asset for official communications, administrative operations and digital services. This domain is used by municipal departments, elected officials, public servants and institutional partners for sensitive exchanges: public procurement, citizen data, legal correspondence and administrative notifications. Email authentication through DMARC, SPF and DKIM represents a critical priority for Caen, which faces risks of domain impersonation, institutional phishing and spoofing targeting residents. Compromise of the caen.fr domain could damage municipal reputation, expose sensitive data and undermine public trust in local digital services. For a territorial collectivity, email domain security aligns with obligations to protect public data and ensure service continuity. Implementing a robust DMARC policy on caen.fr enables validation of legitimate messages, blocks fraudulent emails and generates RUA/RUF reports to monitor impersonation attempts. Faced with escalating cybersecurity threats—particularly those targeting public entities—Caen must strengthen its email authentication infrastructure to protect communications, citizens and digital assets. The DMARC Observatory at dmarc.com provides transparent visibility into the security posture of the caen.fr domain.
