Information security gap analysis: where do you stand and where do you need to go?

An information security gap analysis is a structured assessment of the difference between an organisation's current state of information security and the requirements of a specific framework or standard. It is the ideal first step for organisations working towards ISO 27001 certification, SOC 2 compliance or compliance with NIS2 or DORA.

The purpose of a gap analysis is clear: determine where you stand, where you need to go, and what is needed to close that gap. The result is a prioritised list of improvement points with concrete recommendations, which serves as a roadmap for the compliance process.

The methodology of a gap analysis is structured. The analyst takes the requirements of the chosen standard as a starting point and assesses, for each requirement, whether the organisation fully complies, partially complies, or does not comply. For ISO 27001, the 93 controls from Annex A are systematically reviewed. For SOC 2, the Trust Services Criteria are used as the basis.

For each control, the current maturity is assessed. Is there a policy? Is the policy implemented? Is the implementation monitored? Is there continuous improvement? This maturity model provides insight not only into what is missing, but also into where existing controls are insufficiently mature.

The reporting of a gap analysis typically contains a summary of the current maturity per domain, a detailed list of gaps ranked by risk and impact, concrete recommendations for closing each gap, an indication of the effort required and a proposed timeline.

A gap analysis is not an audit and does not result in an assurance report or certificate. It is an advisory instrument that lays the foundation for a targeted improvement process. Many organisations have a gap analysis carried out by a party other than the auditor who later performs the formal audit, in order to safeguard the auditor's independence.

The investment in a gap analysis pays for itself because the compliance process proceeds in a more targeted and efficient manner. Without a gap analysis, organisations run the risk of spending time and budget on areas that are already adequately arranged, while critical shortcomings go unnoticed.
