Defence and security

Defence and security organisations operate under requirements that most interim providers are not built for. Classified environments, complex governance structures and — in many cases — mandatory security clearances issued by national authorities mean that leadership in this sector demands more than general executive experience.

When interim leadership is used in this sector

The need typically arises in three situations: a leadership vacancy that cannot wait for a permanent hire, a transformation programme requiring experience the organisation does not have internally, or a governance requirement that must be addressed quickly and correctly.

In all three cases, the executive must be able to step in with mandate and credibility from day one. In defence and security, that also means understanding the environment — its structures, its constraints and what is actually at stake.

Security clearances and the role of the Danish Defence Intelligence Service

Many projects in the defence sector require executives in key roles to hold a security clearance. In Denmark, clearances are issued by the Military Security Service at the Danish Defence Intelligence Service (FE). The assessment is based on a concrete evaluation of the individual’s reliability and character in relation to handling classified information.

Private companies supplying technology, consultancy or services to the defence sector — whether for Danish, NATO or EU projects — must also hold a company-level security authorisation. We know the process and can advise on what is required to bring an interim leader into a clearance-dependent environment.

For a detailed overview of how clearances work in practice, see our page on security clearances in the defence sector.

Leadership in complex structures

Defence and security organisations rarely operate in simple hierarchies. Programmes span military and civilian structures, international partners and supplier chains with their own compliance requirements. An interim leader in this environment must be able to coordinate across organisational cultures and decision-making processes — without losing momentum.

That is precisely the type of executive we match. Documented experience from regulated organisations, the ability to work across complex stakeholder structures and a practical understanding of what governance means when it counts.

Discretion as a working condition

Interim assignments in this sector often unfold in the space between openness and confidentiality. The organisation is changing, but the process cannot create instability. Information must be managed correctly — not just legally, but as a leadership discipline.

We handle our part of that equation with the same discretion we require of the executives we place. For more on how sensitive assignments are handled professionally, see our page on discretion and confidentiality in interim leadership.

We have covered three specific topics for this sector in detail:

• Interim management in the defence sector — when it applies and what it requires of the executive
• Security clearances — FE’s framework, the process and what it means for interim leadership in practice
• Discretion and confidentiality — how sensitive assignments are handled professionally

Frequently asked questions

Can you place executives who already hold a security clearance?

Yes. We have profiles with existing clearances issued by the Danish Defence Intelligence Service. If you need an executive who can begin immediately in a classified environment, that is the first thing we clarify when we speak.

What if you do not have the right profile?

We say so directly. We do not place a profile that does not fit — whether that is a question of competence or security requirements. It is better for you and for us.

How quickly can you deliver an interim leader for a defence assignment?

We can present relevant profiles within 48 hours. Lead time depends on the nature of the assignment and any clearance requirements — but we begin the process from the first conversation.

Do you only work with public defence organisations?

No. We also work with private companies supplying technology, consultancy or services to the defence sector — companies operating under the same security requirements as the public organisations they serve.

What does an interim leader cost in this sector?

It depends on the role, the executive’s background and the duration of the assignment. We have outlined the factors that affect fees on our page on what interim management costs.
