Atos Group, formerly known as Atos SE, is a prominent European multinational information technology service and consulting company. Headquartered in Bezons, France, a suburb of Paris, the company operates as a global leader in digital transformation, cybersecurity, high-performance computing, and cloud infrastructure solutions. The company serves public and private organizations across dozens of countries, utilizing an extensive network of offices and global delivery centers to manage business-critical environments, especially in heavily regulated and sovereign contexts. The historical trajectory of Atos is defined by a series of major strategic mergers and acquisitions. The modern entity was originally formed in 1997 through the merger of two French IT services firms, Axime and Sligos. In 2000, it integrated the Netherlands-based Origin B.V. to become Atos Origin. The company rapidly scaled its consulting and operational capabilities by acquiring KPMG Consulting's UK and Netherlands units in 2002 and SchlumbergerSema in 2004. A transformative milestone occurred in 2011 with the acquisition of Siemens IT Solutions and Services, after which the company name reverted to Atos. Subsequent expansions included the purchase of Bull SA and Xerox's IT Outsourcing business in 2014, and the landmark $3.4 billion acquisition of Syntel in 2018. In May 2026, the company officially rebranded to Atos Group. The core operations of Atos Group are structured to deliver end-to-end engineered technology journeys. Its extensive portfolio spans cloud and modern infrastructure, including multi-cloud and edge services, alongside comprehensive digital workplace solutions that optimize enterprise collaboration. As a top cybersecurity provider in Europe, Atos delivers both managed security services and mission-critical products. In the domain of data and artificial intelligence, the organization employs a service-as-software approach, natively embedding automation and generative AI capabilities directly into client operations. Strategic advisory and business consulting are delivered under its dedicated brand, Atos Amplify. Atos Group delivers specialized vertical expertise across numerous sectors, including public defense, manufacturing, financial services, telecom, energy and utilities, healthcare, and transport logistics. Notably, the group has long served as the Worldwide Information Technology Partner for the Olympic and Paralympic Games. In recent years, the company initiated strategic structural transformations, separating its specialized competencies into distinct business lines, including the launch of the Eviden brand to manage professional consulting, big data, and security divisions. Publicly traded on major exchanges under leadership led by Chairman and CEO Philippe Salle, Atos Group maintains a workforce of tens of thousands of global professionals dedicated to shaping secure, sustainable, and intelligence-driven digital futures.
