Saint-Nazaire Agglomération

Saint-Nazaire Agglomération is an intercommunal authority that administers a range of municipal services for the Saint‑Nazaire area. It manages civil registry functions, including the issuance of birth, marriage and death certificates. The organisation processes urbanism requests related to land use and construction permits. It operates public library services, handling loans and related cultural activities. Water and sanitation provision, as well as social aid distribution, fall under its responsibilities. Digital platforms are used for services such as online payments for social aid and appointment booking.

As an intercommunal structure (agglomération) located in France, Saint‑Nazaire Agglomération coordinates services across multiple member communes. Its role includes ensuring continuity of essential public functions even during disruptions, as demonstrated by the shift to manual processing during the April 2024 cyber incident. The organisation collaborates with national cybersecurity agencies such as Orange Cyberdefense and ANSSI to investigate and secure its information systems. Following the attack, it filed a criminal complaint and notified the French data protection authority, CNIL, in accordance with legal obligations. The incident highlighted its dependence on digital infrastructure for service delivery while also showing its capacity to maintain alternative channels like telephone support for urgent needs. These attributes reflect its positioning as a local public entity tasked with both routine administration and crisis resilience.
