Public and private organisations are facing higher threat levels while having to cope with severe budget constraints, which is directly impacting the investment needed to ensure the safety of citizens and defend key national interests. Technological advances concerning connected objects, big data, leading-edge systems, infrastructure modelling etc. offer new perspectives to meet the Defence requirements.

For example, the increasing number of terrorist and cyber-attacks require securing the infrastructures and facilities of sensitive sites. These threats affect all areas (land, sea, air, space and cyberspace), requiring stakeholders to implement comprehensive safety strategies that blend cyber-defence with physical protection.

To cope with budget constraints, the Defence sector needs to be more efficient and exhibit greater operational availability, both in France and elsewhere. This requires economic discipline with analytic efforts in resources control, as well as Maintenance in Operational Condition and system/equipment interoperability. Digital technology is one of the levers supporting the in-depth transformation needed to achieve these objectives, in full respect of applicable defence policies and the associated financial requirements, as exhibited in the French Military Planning Law for example.

The Military Planning Law plays a major role in France, as it sets out the objectives of the national Defence policy and the associated forward budget, to ensure the security of people and vital national interests.

Defence economy: improve the efficiency of resource use

The Defence sector must set up rigorous analytic management to improve its efficiency given the higher budgetary pressure stakeholders are facing. These economic efforts are required in multiple fields: human resources, investment (infrastructures and armaments), procurement, exports, outsourcing etc. This requires the implementation of tried and tested financial management models, statistical tools and rigorous economic analysis.

modernisation of infrastructures

Modernisation of infrastructures and systems

In the Defence sector, modernisation implies that investment must be maintained yet more efficiently and at a lower cost. This also requires organisations to refocus on their core business activities and integrate new technologies, especially concerning big data and 3D modelling.

security of infrastructures defence

Guarantee the physical security and cybersecurity of sensitive sites

It is essential to secure activities, sensitive sites, infrastructures and particularly OVI, while deploying alert systems to detect and neutralise potential intrusions. OVI (Operators of Vital Interest) or OES (Operators of Essential Services) are sensitive sites that are critical to the survival of the economy and society, the shutdown of which would have direct consequences on the population. Beyond the protection of infrastructures, it also requires us to anticipate and assess risks in order to prevent them. An appropriate cyber-security strategy will prevent the risk of network intrusion for the purposes of espionage, remote takeover or destruction of vital infrastructures.

operational readiness defence

Operational readiness of systems and equipment

Ensuring that people and equipment are available is a national security issue, so that intervention is possible anywhere, any time. The dependability of systems and solutions is therefore a key issue. Guaranteeing the interoperability and security of critical operational systems to ensure international dialogue in real time is a key driver for Defence sector organisations.


As an independent French engineering group with a robust international presence, Assystem has over 50 years of experience in complex and constrained environments.  We work with many types of clients, from military bases, government bodies, OVI and Defence sector stakeholders. We offer key project management skills for major infrastructure programmes and systems integration, alongside technological independence.

Assystem supports private sector or Defence ministry project managers in their projects for new constructions, protection of sensitive sites (physical protection and cybersecurity), and in equipment obsolescence management (Maintenance in Operational Condition). We can deliver full project management services, from inception and design through to the acceptance of work. We have teams of experts in BIM (Building Information Modelling) who use this approach from the design phase through to infrastructure maintenance (3D pre-synopsis and synopsis, exports and post-design modifications, reverse design of existing structures etc.).

We also offer key technical skills in Defence activities, such as compliance with security standards specific to the Defence sector (ASND - French Defence Nuclear Safety Authority), on-board systems (propulsion, weapons systems etc.), risk analysis integrating operational constraints on complex sites and transmission systems, not forgetting our extensive historical experience in the French and international civil nuclear sector.

Management of complex projects

We coordinate multidisciplinary project teams from the initial project feasibility stage through to handover of facilities. The facilities must meet specific requirements in terms of operational readiness of infrastructures, safety and security obligations. We also offer PMO expertise: structuring, deadlines, costs, risks, resources etc. across all project phases.

management complex project

Expertise in Nuclear programmes

We offer unique nuclear expertise that is renowned around the world. Active in all phases of the nuclear life cycle, from siting to dismantling. Our teams of 2,800 people work hand in hand with all nuclear technology suppliers around the world.


Comprehensive safety

The physical safety of people and sites, functional and cybersecurity are both complementary and interdependent. Our teams work in all these areas to deliver efficient and global protection for Defence infrastructures.


Digital transformation

We propose an array of solutions in digital engineering, architecture and integration of industrial information systems, to raise the performance of our clients' systems. These technologies must be introduced, as digital technology has a growing, dominant role in Defence.
