# 28 leading critical infrastructure operators in the Morbihan department

Tamtam tracks 28 critical infrastructure operators headquartered in the Morbihan department. This list ranks all of them by number of employees on LinkedIn, led by Crédit Agricole du Morbihan, GROUPE HOSPITALIER BRETAGNE SUD and Service Départemental d'Incendie et de Secours du Morbihan (SDIS56). Their median headcount is 107. Half of them were founded in 2001 or later. The most common headquarters are Lorient (10) and Vannes (8).

The critical infrastructure operators in Morbihan are predominantly public sector entities and healthcare providers. These include major public service organizations such as Service Départemental d'Incendie et de Secours du Morbihan (SDIS56), which manages emergency interventions, and Cap l'Orient agglomération, a group of 19 communes focused on territorial development. Healthcare is well represented by institutions like GROUPE HOSPITALIER BRETAGNE SUD, offering extensive medical care, and EPSM Morbihan, providing psychiatric services. Crédit Agricole du Morbihan, a regional bank, is also a significant employer.

A notable pattern is the concentration of headquarters in Vannes and Lorient, reflecting these cities' roles as administrative and economic hubs in the department. Many of these organizations are well-established, with several founded in the early to mid-20th century, indicating a long-standing commitment to public service and regional development.

## 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.
