AresISEC ISO 27001 ISMS Readiness Assessment
Assessing your readiness to work toward an ISO 27001 ISMS
A clear overview of your current position and the areas that need attention before moving forward with your ISMS.
An ISO 27001 ISMS GAP analysis helps an organisation understand how prepared it is to meet the requirements of an information security management system.
The goal is not to create an impression of formal compliance. It is to determine whether the organisation has a solid enough foundation for further ISMS work. The analysis shows what is already in place, where gaps exist, which areas lack sufficient evidence and what should be addressed before further decisions are made. ISO 27001 requires more than policies and procedures. An organisation must understand its business context and risks, assign clear responsibilities, know which information assets it manages and be able to demonstrate how security measures work in practice.
AresISEC uses a structured GAP review to assess available documentation and input from responsible personnel, existing records, security practices and the technical information relevant to the ISMS.
What does the analysis clarify?
Many organisations already have security measures, internal rules, technical controls and established business processes. These are not always connected within a clear and demonstrable ISMS framework. The ISO 27001 ISMS GAP analysis separates existing practices from areas that genuinely need further work. Particular attention is given to issues that commonly cause problems later, including unclear ISMS boundaries, undefined responsibilities, incomplete registers, missing evidence, informal processes and security measures that are not linked to identified risks.
The focus is on what actually exists. If something relies only on a verbal agreement or an informal practice, or consists of a technical measure without clear ownership and supporting evidence, it is identified as an area that requires further work.
Analysis process
The analysis is carried out through a structured questionnaire and review of the minimum required evidence, with additional clarification where necessary. The assessment is based on information the organisation can actually provide: documents, records, process descriptions, system inventories, supplier lists, existing internal rules, technical information and other available evidence.
We do not assume that an area is adequately managed simply because a tool, document or internal practice exists. We look at who is responsible and what is actually being done, whether records exist and how these activities relate to information security. This provides a practical basis for deciding what needs immediate attention, what can wait, where additional evidence is needed and which issues may significantly affect further ISMS work.
Areas we review
The ISO 27001 ISMS GAP analysis reviews the areas needed to understand the organisation’s initial level of ISMS readiness.
These include organisational context, interested parties, ISMS boundaries, responsibilities, information assets, suppliers, access management, existing policies and procedures, security incidents, business continuity, baseline technical controls and available evidence. Particular attention is given to whether the organisation can clearly explain what it protects, which systems and information are important to the business, who is responsible for individual activities and whether records demonstrate how security is handled in practice.
What do you receive?
After the analysis, you receive a structured view of the current state and identified gaps, together with open questions and recommended priorities. The report can be used for internal planning and management discussions, to estimate the work required for the ISMS and to make informed decisions about the next steps.
Depending on the selected level of analysis, the client receives:
- an overview of current ISO 27001 ISMS readiness
- identified gaps and areas where supporting evidence is insufficient
- an overview of relevant areas, systems, documents and responsibilities
- priorities assessed according to risk and business impact
- recommendations for further ISMS activities
- a concise or full ISO 27001 ISMS GAP report, depending on the selected level of analysis
The ISO 27001 ISMS GAP analysis is not an ISMS implementation service and does not replace a certification audit. It does not include drafting client policies, procedures or registers, preparing the SoA, conducting a formal risk assessment, performing an internal audit or preparing the organisation for certification unless any of these activities are agreed separately at a later stage.
Who is the service for?
The ISO 27001 ISMS GAP analysis is intended for organisations that want to understand how prepared they are for structured work on an ISMS.
It is particularly useful for small and medium-sized organisations without a large internal security or compliance team that want to establish a sustainable approach to information security management.
The service is also suitable for organisations that already have documentation, technical controls, internal rules or established security practices but are unsure how these fit into an ISO 27001 framework or whether there is enough evidence to demonstrate that they are actually being followed.
The ISO 27001 ISMS GAP analysis primarily assesses documentation, processes, responsibilities, available evidence and security practices. In some cases, documentation alone is not enough to understand the actual technical state of the environment. Where appropriate, AresISEC may recommend a targeted technical assessment as a separate addition to the GAP analysis. These assessments are not a mandatory part of the standard GAP package. They are used when the analysis identifies higher risk or when there is insufficient evidence about the actual technical condition of the environment.
AresISEC services that can complement the ISO 27001 ISMS GAP analysis
- Vulnerability Assessment helps assess the technical exposure of systems and weaknesses such as misconfigurations.
- Penetration Testing is used when it is necessary to determine whether an identified weakness can be exploited in a realistic attack scenario.
- Security Infrastructure Design helps when the analysis identifies weaknesses in segmentation, access controls, monitoring or system architecture.
- Ransomware Protection and Recovery complements the analysis when backup protection, recovery, business continuity or incident handling need to be assessed.
- Source Code Security Analysis is useful for organisations that develop their own applications and need a clearer view of security risks within the software development process.
Why AresISEC
AresISEC does not treat ISO 27001 as a documentation exercise. Information security must reflect how the organisation actually operates and be connected to its systems, responsibilities, risks and demonstrable evidence.
Our approach combines practical security consulting with experience in security testing and technical risk assessment. During the GAP phase, this helps distinguish formal shortcomings from issues that have a real impact on the organisation’s security. The purpose of the analysis is straightforward: to show where you are now and what is already in place, identify what still needs work and provide a sensible direction for the next stage of your ISMS.
