Mission

In a global defense group, security is part of the organization’s DNA. It shapes its products, systems, client commitments, and culture of excellence.

But even in such a sensitive environment, security does not become part of projects by decree. To exist in practice, it must come in at the right moment, be carried by the right relays, be translated into the language of project teams, and be experienced as a contribution to project success — not as a constraint added at the end of the process.

This was the central lesson of the mission: security becomes fully effective only when it moves beyond after-the-fact control and becomes a design capability, embedded from the earliest stages of projects.

The Group Security department wanted to take the next step: strengthen security in projects, starting with IT and progressively extending the approach to business projects. The challenge was to help the security function shift toward an advisory posture: earlier, clearer, and closer to operational realities.

The mission entrusted to Adviso: structure this evolution in a demanding international context, combining change management, security awareness, community activation, process clarification, and business-facing communication.

Solution

Adviso set up a focused approach to turn a security ambition into an operational capability.

The first lever was the posture of security leads. Their value does not lie only in checking compliance, but in helping projects anticipate risks, ask the right questions, and make the right trade-offs earlier. Security then becomes a design partner, not a mandatory checkpoint.

The second lever was to bring security earlier into the project lifecycle. Entry points, moments of intervention, qualification criteria, roles and responsibilities: the objective was to make the process clear for project teams, so they know when to involve security, whom to work with, and what to expect.

The third lever was the structuring of a community of security correspondents. In a global organization, a policy alone does not change practices. It needs relays able to translate requirements into project realities, share the right reflexes, surface friction points, and create coherence across entities.

The work also addressed the tools: clarifying what already existed, identifying gaps, simplifying support materials, and imagining the formats project teams actually need — guides, checklists, messages, rituals, and awareness materials.

Finally, communication toward the business was redesigned. Less jargon, more clarity on the project value of security: what it helps prevent, what it accelerates, what it secures, and what it makes possible.

By the end of the mission, the Group Security department had a stronger frame to embed security into projects: a clearer advisory posture, a more legible process, a community of relays to activate, tools to consolidate, and communication more directly connected to the business.

In sensitive organizations, security cannot remain an expertise that steps in too late. It must become a capability embedded into projects from the design stage — serving risk control, but also performance and trust.

Adviso was able to grasp the complexity of our environment at the right level. Their expertise in security awareness was an exceptional — and rare — asset in delivering the right messages at the right time and achieving tangible results.
