# List of critical infrastructure operators in the Gironde department
Tamtam tracks 63 critical infrastructure operators headquartered in the Gironde department. This list ranks the 30 largest by number of employees on LinkedIn, led by CHU de Bordeaux, Bordeaux Métropole and Crédit Agricole d'Aquitaine. Their median headcount is 517. Half of them were founded in 1977 or later. The most common headquarters are Bordeaux (18), Pessac (3) and Bruges (2).
This selection of critical infrastructure operators in Gironde primarily features large public and private sector entities. The list includes several major healthcare providers such as CHU de Bordeaux, a university hospital, and Institut Bergonié, a private cancer treatment center. Financial institutions are also prominent, with Crédit Agricole d'Aquitaine, Caisse d'Epargne Aquitaine Poitou-Charentes, and Banque Populaire Aquitaine Centre Atlantique among the largest regional banks. Bordeaux Métropole, an intercommunal organization, represents local government administration.
A clear pattern is the strong concentration of headquarters in Bordeaux. Most of the listed companies, including Keolis Bordeaux Métropole Mobilités, which manages public transportation, and Service Départemental d'Incendie et de Secours de la Gironde (SDIS 33), the departmental fire and rescue service, are based in the city. This indicates Bordeaux's central role as an economic and administrative hub for critical services within the department.

## How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
