Sale of Group Atlas Sécurité to BSL
Paris (France), June 18th, 2025
Founded in Rouen in 2003 by Stéphane Chergui, Atlas Sécurité is one of the leading independent players in physical security, surveillance, and reception services in the west of France. With revenues of nearly €35 million, primarily generated from major corporate clients and public institutions, the Group is pursuing a strategy of sustained growth, illustrated in particular by the acquisition of an agency in Nantes in 2020, which strengthened its presence along the Atlantic coast.
Atlas Sécurité is also a member of the Securalliance, alongside Groupe BSL.
As part of this dynamic, Groupe BSL is acquiring Atlas Sécurité with the aim of:
- Expanding geographic coverage and building a national group: Atlas has a strong historical presence in the Grand Ouest (Normandy, Brittany, Pays de la Loire), while BSL operates in the Île-de-France and South-East regions;
- Accelerating commercial development: leveraging shared key account references and scaling up for complex tenders by combining geographic coverage, sector expertise, and enhanced operational capabilities;
- Creating operational synergies and sharing Atlas’s newly launched training center.
This transaction once again highlights Financière de Courcelles’ expertise in supporting founder-managers and the business services sector.
