ISO 27001
GAP Assessment
A deep-dive, board-ready assessment that shows exactly how far your organization is from full ISO/IEC 27001:2022 compliance. We benchmark your ISMS, map control maturity, reveal structural gaps, and deliver a clear, prioritized roadmap toward certification readiness.
- Full ISMS maturity review benchmarked against ISO/IEC 27001:2022 requirements.
- Detailed gap identification across Clauses 4–10 and all Annex A security controls.
- Prioritized remediation roadmap with estimated effort, ownership, and timelines.
- Executive-level insights enabling confident planning toward certification.
Why is an ISO 27001 GAP assessment critical for your organization?
An ISO 27001 GAP assessment provides the structured, analytical baseline you need before pursuing certification. Instead of going directly into an audit, your organization first understands how its Information Security Management System (ISMS) aligns with ISO/IEC 27001:2022 requirements across Clauses 4–10 and Annex A controls.
Rather than simply confirming compliance, a GAP assessment focuses on gaps, weaknesses, and maturity levels in your current security practices. It translates the standard into practical, organization-specific insights: what is missing, what is partially implemented, and what is already strong enough for certification expectations.
EntrySec delivers GAP assessments led by experts who combine ISO 27001 implementation experience with real-world cybersecurity backgrounds. Our lead auditors and senior pentesters provide objective ISMS maturity scoring and a prioritized remediation roadmap, so leadership can plan investments, sequence tasks, and move toward internal audits and certification with clarity and confidence.
ISO 27001 GAP Assessment Highlights
Baseline vs ISO Requirements
We map your current ISMS practices against ISO/IEC 27001:2022 clauses and Annex A controls to identify where you stand today.
Structured GAP Identification
Every deviation, missing control, or weak practice is documented as a concrete gap with clear links to the relevant ISO requirements.
ISMS Maturity Scoring
Control areas are scored by maturity so leadership can see which parts of the ISMS are ad-hoc, repeatable, or fully optimized.
Prioritized Remediation Roadmap
We turn findings into a sequenced remediation plan with ownership, effort level, and suggested timelines for each action.
Certification Readiness View
Your team receives a clear picture of how close you are to ISO 27001 certification and which gaps must be addressed first.
Foundation for Audits
The GAP assessment provides the evidence and structure needed to plan internal audits and the eventual certification audit.
ISO 27001 GAP Assessment Roadmap
A clear, structured roadmap showing how EntrySec executes your ISO 27001 GAP assessment — from discovery and evidence review to full clause and control analysis, maturity scoring, and prioritized remediation.
Discovery & Scoping
We define ISMS boundaries, business context, technologies, critical assets, and assessment scope tailored to your certification goals.
Documentation & Evidence Review
Your team securely provides policies, SoA, risk registers, inventories, HR/security procedures, and any previous audits or assessments.
Workshops & Control Walkthroughs
We meet with key stakeholders to understand how controls operate in practice across governance, HR, IT, operations, and security.
Clause 4–10 Alignment Review
We evaluate your ISMS governance structure, leadership involvement, risk methodology, support processes, performance, and improvements.
Annex A Control GAP Analysis
We map current practices against the 93 Annex A controls to identify missing, weak, or partially implemented controls with clear ISO references.
ISMS Maturity Scoring
Each control domain is scored using a structured maturity scale, giving leadership an objective baseline to measure ISMS progress.
Prioritized Remediation Roadmap
We deliver a sequenced remediation plan with owners, effort scoring, suggested timelines, and a certification readiness score.
What Comes After the GAP Analysis?
Turn ISO 27001 GAP Findings Into a Certification-Ready ISMS
A single structured flow that transforms GAP results into corrective actions, implemented controls, and full audit readiness.
Develop a Corrective Action Plan
Once the GAP Analysis is complete, the real work begins—turning findings into a structured, prioritized remediation roadmap.
Document all gaps clearly: capture missing policies, weak controls, and incomplete Annex A implementations.
Perform root cause analysis: address the underlying origin of issues, not just the visible symptoms.
Prioritize based on risk: rank remediation tasks by impact, likelihood, and readiness relevance.
Assign clear ownership: ensure each remediation has a responsible owner or team.
Set realistic deadlines: sequence tasks based on dependencies and available resources.
Benefits of an ISO 27001 GAP Assessment
A GAP assessment provides clarity, direction, and a pre-certification strategy that strengthens your ISMS and accelerates your path to ISO 27001 readiness.
Full Visibility of Your ISMS Gaps
A GAP assessment maps your current ISMS against ISO/IEC 27001:2022, revealing missing requirements, weak implementations, and areas needing improvement.
Clear, Structured Remediation Roadmap
You receive a sequenced, prioritized roadmap detailing exactly what must be built, refined, or corrected before internal and external audits.
Improved ISMS Maturity
The assessment scores maturity across ISO domains so leadership can see which areas are ad-hoc, repeatable, or well-optimized—and where to invest first.
Better Documentation & Control Alignment
Policies, procedures, the SoA, risk register, and Annex A mappings are reviewed for completeness, consistency, and alignment with certification expectations.
Reduced Certification Risk
By resolving gaps early, you minimize surprises during the internal audit and ensure a smoother, more predictable external certification audit.
Strategic Decision-Making for Leadership
Executives receive clarity on effort, budget, risks, and timelines—enabling informed decisions about readiness, prioritization, and resource allocation.

Frequently Asked Questions
Clear and straightforward answers to the most common questions about our ISO 27001 GAP Assessment services and how they help you understand your current security posture and prepare confidently for certification.
An ISO 27001 GAP assessment is a structured review that compares your current Information Security Management System (ISMS) against the requirements of ISO/IEC 27001:2022. Instead of issuing non-conformities, it identifies missing requirements, weak areas, and improvement opportunities so you know exactly what must be addressed before internal and external certification audits.
Most organisations perform a GAP assessment early in their ISO 27001 journey—before designing or finalising the ISMS—or shortly before seeking certification to validate their readiness. It is also valuable before re-certification or after major changes such as restructuring, new products, or significant changes to the technology stack or risk profile.
A GAP assessment usually includes reviewing your existing policies and procedures, the Statement of Applicability, risk assessment and treatment approach, Annex A control coverage, supplier and incident processes, and how information security is embedded in day-to-day operations. The outcome is a clear list of gaps, maturity observations, and a prioritized remediation roadmap linked to ISO 27001 requirements.
A GAP assessment is a readiness and improvement exercise, not a formal audit. It focuses on identifying what is missing or not yet strong enough to meet ISO 27001 expectations, and on providing guidance to close those gaps. An internal audit verifies whether the implemented ISMS is effective and compliant, while an external certification audit is performed by a certification body to formally grant or maintain ISO 27001 certification.
By identifying weaknesses early—before the internal and external audits—a GAP assessment allows you to address issues proactively. This reduces the risk of non-conformities during certification, improves the effectiveness of your ISMS, strengthens governance and risk management, and ultimately lowers the likelihood of security incidents or compliance failures.
Yes. We offer a free consultation to understand your current ISMS maturity, scope, and certification goals. During this call, we explain how our GAP assessment works, what evidence we review, what deliverables you receive, and how the results can be used to plan remediation, internal audits, and the external certification audit.
