Always operational
Ensuring system availability and operational continuity.
System support and operational on-site organization: a comprehensive approach to keeping operations running.
Operational continuity, from systems to sites
For more than 40 years, ISD Group has supported defense and mission-critical organizations in managing support engineering, through-life support (MCO) and operational support, in France and worldwide.

The performance of a system is measured by its ability to remain available, reliable and operational over time.
ISD Group works at the heart of operations to structure, deploy and maintain the support organizations and resources required to sustain that continuity, for both equipment and the operational environments in which it is used.
We support manufacturers, operators and public institutions in addressing availability, maintenance and operational organization challenges.
Two complementary expertises. One operational standard.

Operational Equipment Support
Support engineering, through-life support, technical assistance, training.
ISD designs, organizes and deploys the support capabilities required to ensure the availability of complex systems.


Operational on-site support
Logistics, flow management, support services, transportation.
Through its Euralog entity, ISD Group structures and manages the operations required to keep sites running effectively.

A comprehensive approach of sustainment, from the system to its operating environment.
An operational presence in France and internationally
