Über Cannes
The city of Cannes, a French local authority located in Provence-Alpes-Côte d'Azur, manages a complex email perimeter encompassing municipal services, official communications, citizen notifications and inter-administrative correspondence. The cannes.com domain represents a critical communication vector for this public local organization, used by elected officials, territorial agents and digital services to exchange with residents, institutional partners and suppliers. Securing this domain is strategically important given the risks of identity spoofing, business email compromise and erosion of public trust. Local authorities, as critical entities within the public sector, must comply with enhanced cybersecurity obligations, particularly under the NIS2 Directive and its national implementations. The robust implementation of email authentication protocols (SPF, DKIM, DMARC) on cannes.com is part of this digital infrastructure security enhancement approach. The DMARC Observatory on dmarc.com documents the deployment status of these protection mechanisms for French municipal domains, enabling local authorities to assess their email security posture and identify gaps in their authentication chain. This inventory provides transparency regarding the adoption of cybersecurity best practices within local administrations, a key factor in the overall resilience of the French public sector against fraud and compromise threats.
