ISD Group is continuing its development with the integration of Euralog, a specialist in on-site services for sensitive environments. This new step strengthens the Group’s positioning around a key challenge for its customers: ensuring the operational continuity of equipment, sites and field operations.
Together, ISD Group and Euralog represent nearly 130 employees, a multi-site presence in France and combined revenue of more than €14 million.
For more than 40 years, ISD has supported Defense organizations and major industrial players through support engineering, maintenance in operational condition, technical assistance, technical documentation and training. The Group operates in France and internationally, in environments where equipment availability, operational reliability and field-level constraints are critical.
With Euralog, ISD Group expands its scope to include on-site operational services: logistics, transport, flow management, mobility and field support. These capabilities complement ISD’s historical expertise and allow the Group to support customers across a broader operational chain, from equipment support to the day-to-day functioning of critical sites.
This complementarity addresses concrete needs across Defense, nuclear, energy, aerospace and other mission-critical industries. In these environments, performance depends on the quality of equipment, the availability of skilled teams, the fluidity of flows and the ability to keep operations running over time.
“This integration strengthens our ability to support customers over the long term, with a comprehensive approach to operational continuity. By combining support engineering, MCO and on-site operations, we now cover the full range of capabilities required to keep systems and critical environments functioning effectively. Our priority remains unchanged: to stay operational, always.”
Benjamin Videt, CEO of ISD Group
ISD and Euralog will retain their respective identities, organizations and areas of expertise. Their integration is built on a shared field-oriented culture, rooted in commitment, operational excellence, reliability, responsiveness and team spirit.
“Joining ISD Group allows us to be part of a coherent project, fully aligned with what we have been doing for more than 40 years: ensuring the day-to-day functioning of sites. The complementarity between our areas of expertise strengthens our ability to meet our customers’ operational requirements.”
Matthieu Rouanet, CEO of Euralog
With this new dimension, ISD Group confirms its ambition: to support industrial and institutional players in mission-critical environments with concrete, operational and field-oriented solutions.
Always Operational.
