How the engagement works

Each engagement begins with a assessment of the current security posture, mandate, and risk landscape. Based on this, priorities are defined together with senior management to ensure alignment with business objectives and compliance obligations.

The role can be scoped as:

  • Full interim CSO responsibility

  • Time-limited leadership during transition

  • Reinforcement of an existing security organization

The engagement is structured, discreet, and focused on executive-level outcomes.

Outcome for leadership

For CEO and HR leadership, the result is:

  • Maintained accountability and ownership of security matters

  • Reduced operational and regulatory risk during transition

  • Clear decision support at senior management level

  • Stability within the security function and the wider organization

“Our goal was to keep the function at its current level. Instead, it developed further and exceeded what we had anticipated.”

Why Interim Security Officer (CSO)

Organizations cannot afford gaps in security leadership. When a Chief Security Officer leaves, is unavailable, or when risk exposure increases, immediate continuity is essential. An Interim Chief Security Officer (CSO) provides senior security leadership to maintain control, stability, and informed decision-making while a permanent solution is secured.

This role is designed for organizations operating in critical, regulated, or security-sensitive environments where delays, unclear ownership, or weakened governance introduce unacceptable risk.

Role and responsibility

As Interim Chief Security Officer, responsibility is assumed at senior management level with a clear mandate to lead, stabilize, and align the security function with organizational priorities. The role typically includes:

  • Overall responsibility for security governance and leadership

  • Oversight of physical security, information security, personnel security, and protective security

  • Risk and threat assessment aligned with business and regulatory requirements

  • Advisory support to CEO and senior management

  • Coordination with legal, HR, IT, and operational leadership

  • Representation of the security function towards authorities, auditors, and key stakeholders

The focus is on control, clarity, and continuity—not on long-term restructuring unless explicitly requested.

When an Interim CSO is relevant

An Interim Chief Security Officer is typically engaged when:

  • A permanent CSO or Head of Security has left or is temporarily unavailable

  • The organization is undergoing restructuring, growth, or increased regulatory scrutiny

  • Security risk exposure has changed due to external events, incidents, or new requirements

  • Executive management requires immediate senior security leadership without delay

The interim engagement creates time and stability for leadership to make well-founded long-term decisions.
