How to conduct ISO 27001 gap analysis using ISMS Copilot

Overview

You'll learn how to use ISMS Copilot to conduct a comprehensive ISO 27001 gap analysis, identifying gaps between your current security posture and ISO 27001:2022 requirements to create a prioritized remediation roadmap.

Who this is for

This guide is for:

  • Security professionals assessing readiness for ISO 27001 certification

  • Compliance officers evaluating existing security controls

  • Organizations transitioning from ISO 27001:2013 to 2022

  • Consultants performing client readiness assessments

  • IT managers preparing for internal or external audits

Prerequisites

Before starting, ensure you have:

  • An ISMS Copilot account (free trial available)

  • Access to existing security policies, procedures, and documentation

  • Understanding of your organization's scope and operations

  • Ability to upload documents (PDF, DOCX, XLS formats supported)

Before you begin

Set realistic expectations: A thorough gap analysis takes 2-4 weeks to complete properly, even with AI assistance. Rushing this process can lead to missed gaps that surface during certification audits, causing costly delays.

What is a gap analysis? A gap analysis systematically compares your current information security practices against ISO 27001 requirements (clauses 4-10 and applicable Annex A controls) to identify missing, incomplete, or inadequate controls. The output is a prioritized action plan to achieve compliance.

Understanding ISO 27001 gap analysis

What you're assessing

ISO 27001 gap analysis evaluates two critical areas:

1. Management system requirements (Clauses 4-10):

  • Context of the organization (scope, interested parties)

  • Leadership and commitment (policies, roles, responsibilities)

  • Planning (risk assessment methodology, treatment plans)

  • Support (resources, competence, documented information)

  • Operation (risk assessment execution, control implementation)

  • Performance evaluation (monitoring, internal audit, management review)

  • Improvement (nonconformity handling, continual improvement)

2. Security controls (Annex A - 93 controls across 4 themes):

  • Organizational controls (37 controls): policies, governance, HR security

  • People controls (8 controls): screening, awareness, disciplinary process

  • Physical controls (14 controls): access control, environmental security

  • Technological controls (34 controls): encryption, access management, logging

Gap analysis outcomes

A complete gap analysis delivers:

  • Gap assessment report documenting current vs. required state

  • Risk-based prioritization of identified gaps

  • Estimated effort and resources for remediation

  • Implementation roadmap with timelines

  • Quick wins vs. long-term initiatives

  • Budget and resource requirements

Pro tip: Conduct gap analysis before committing to certification timelines. Organizations commonly underestimate remediation time by 40-60%, leading to missed deadlines and rushed implementations that fail audits.

Step 1: Set up your gap analysis workspace

Create a dedicated workspace

  1. Log into ISMS Copilot

  2. Click the workspace dropdown in the sidebar

  3. Select "Create new workspace"

  4. Name it: "ISO 27001:2022 Gap Analysis - [Your Organization]"

  5. Add custom instructions:

Conduct ISO 27001:2022 gap analysis for:

Organization: [Company name]
Industry: [e.g., SaaS, healthcare, fintech]
Size: [employees, locations]
Current state: [starting fresh / have policies / SOC 2 certified]
Technology: [cloud infrastructure, data centers, hybrid]
Compliance: [existing frameworks like SOC 2, HIPAA, GDPR]

Analysis focus:
- Identify gaps against ISO 27001:2022 requirements
- Prioritize by risk and implementation effort
- Provide practical remediation guidance
- Reference specific controls and clause numbers
- Suggest evidence requirements for audit readiness

Result: All gap analysis queries will receive context-aware responses tailored to your organization's specific situation, improving relevance and reducing back-and-forth.

Step 2: Assess management system requirements (Clauses 4-10)

Clause 4: Context of the organization

Ask ISMS Copilot to help identify what's required:

"What documented information does ISO 27001:2022 Clause 4 require for understanding organizational context, interested parties, and ISMS scope? For each requirement, provide a checklist I can use to verify completeness."

Then assess your current state:

"I have [describe your current documentation: scope statement, stakeholder analysis, or nothing]. Identify gaps against ISO 27001 Clause 4 requirements and suggest what documentation I need to create."

If you have existing documentation, upload it:

  1. Click the paperclip icon or drag and drop your scope document (PDF, DOCX)

  2. Ask: "Analyze this ISMS scope document against ISO 27001:2022 Clause 4.3 requirements. Identify missing elements, weak areas, and suggested improvements."

Clause 5: Leadership

Evaluate leadership commitment and Information Security Policy:

"What are the mandatory requirements for the Information Security Policy under ISO 27001:2022 Clause 5.2? Create a gap assessment checklist."

Upload your existing Information Security Policy (if any):

"Review this Information Security Policy against ISO 27001:2022 Clause 5.2 requirements. Check for: management commitment statement, security objectives, continual improvement commitment, and legal compliance commitments. List specific gaps."

Clause 6: Planning (Risk assessment and treatment)

This is often where significant gaps exist. Assess your risk management approach:

"What documented information is required for ISO 27001 Clause 6.1 (risk assessment and treatment)? Include: risk methodology, risk assessment results, risk treatment plan, and Statement of Applicability requirements."

If you have risk assessments, upload them:

"Analyze this risk assessment against ISO 27001:2022 requirements. Check if it includes: asset identification, threat and vulnerability analysis, likelihood and impact evaluation, risk calculation methodology, risk owner assignment, and treatment decisions. Identify gaps."

Common gap: Many organizations have risk assessments but lack documented risk methodology. ISO 27001 requires defining your approach BEFORE conducting assessments. Missing methodology is a major nonconformity.

Clause 7: Support (Resources and competence)

Assess resource allocation and training:

"What evidence does ISO 27001 Clause 7 require for: resource allocation, competence and training, awareness programs, and communication processes? For a [company size] organization, what realistic implementation looks like?"

Clause 8: Operation

Evaluate operational processes:

"What operational processes and documented procedures does ISO 27001 Clause 8 require? Include: operational planning, risk assessment execution, risk treatment implementation, and change management. Create assessment criteria."

Clause 9: Performance evaluation

Check monitoring and audit capabilities:

"What are ISO 27001 Clause 9 requirements for: monitoring and measurement, internal audit program, and management review? For each, specify: frequency, documentation requirements, and scope. What gaps exist if we currently have [describe current state]?"

Clause 10: Improvement

Assess continual improvement processes:

"What processes does ISO 27001 Clause 10 require for: handling nonconformities, corrective actions, and continual improvement? How should these be documented? What evidence is needed?"

Step 3: Assess Annex A controls

Generate comprehensive control assessment

Start with a complete control inventory:

"Create a gap analysis template for all 93 ISO 27001:2022 Annex A controls. For each control, include: control reference, title, description, current implementation status (not implemented / partially / fully), gap description, priority (high/medium/low), estimated effort, and recommended actions. Format as a table."

Assess by control theme

Evaluate each theme systematically:

Organizational controls (A.5.1 - A.5.37)

"For ISO 27001 Annex A organizational controls (A.5.1 through A.5.37), describe each control's objective and typical implementation approaches for a [industry] company. For each control, ask: What policy/procedure is needed? What evidence demonstrates implementation? What tools are commonly used?"

Then assess your current state for specific controls:

"I currently have [describe your policies: information security policy, access control policy, acceptable use, etc.]. Map these to Annex A organizational controls. Which controls do these policies address? Which controls have no coverage? What additional policies are needed?"

People controls (A.6.1 - A.6.8)

"Evaluate people controls A.6.1 through A.6.8 for gap analysis. For a remote-first company with [employee count], what realistic implementation looks like for: screening procedures, employment agreements, security awareness training, and disciplinary process?"

Physical controls (A.7.1 - A.7.14)

"We operate [describe environment: cloud-only, hybrid, on-premise data centers]. For physical controls A.7.1 through A.7.14, which controls apply to our scope? Which can be excluded with justification? For applicable controls, identify implementation gaps."

Pro tip: If you're fully cloud-based (AWS, Azure, GCP), many physical controls may not apply to YOUR scope. However, you must verify your cloud provider implements them. Ask: "What physical controls can I exclude for cloud-only operations? What evidence do I need from my cloud provider (e.g., SOC 2 reports)?"

Technological controls (A.8.1 - A.8.34)

"For technological controls A.8.1 through A.8.34, assess our current implementation. We use: [list your technology stack: identity provider, SIEM, endpoint protection, encryption tools, backup solutions, vulnerability scanner]. Map these tools to applicable controls. Identify controls with no technical implementation."

Upload existing documentation for automated gap identification

For efficient analysis, upload multiple documents:

  1. Upload your current security policy collection (up to 10MB per file)

  2. Ask: "Review these policies and identify which ISO 27001:2022 Annex A controls they address. Create a coverage matrix showing: Control ID, Control Title, Addressed by Policy, Coverage Level (None/Partial/Full), Gap Description."

  3. Follow up with: "For controls marked as 'None' or 'Partial', suggest specific policy sections or new procedures needed to achieve full compliance."

Step 4: Prioritize identified gaps

Risk-based prioritization

Not all gaps are equal. Prioritize by asking:

"Prioritize these identified gaps using these criteria: 1) Risk to certification (auditor will fail us), 2) Information security risk (could lead to incident), 3) Implementation complexity (time and resources), 4) Dependencies (blocks other work). Create a priority matrix."

Quick wins vs. strategic initiatives

Identify what can be fixed quickly:

"From this gap analysis, identify: 1) Quick wins achievable in 2-4 weeks (policy updates, documentation), 2) Medium-term projects requiring 1-3 months (process implementation, tool deployment), 3) Strategic initiatives needing 3+ months (cultural change, major technical implementation). Categorize all gaps."

Estimate effort and resources

Get realistic implementation estimates:

"For each identified gap, estimate: person-hours required, skillsets needed (internal or consultant), technology investments, timeline, and dependencies. For a [company size] organization with [IT team size], what's realistic for resource allocation?"

Budget reality check: Closing significant gaps typically requires 15-25% of an FTE's time over 3-6 months, plus external consulting or tools. Underfunding gap remediation is the leading cause of failed certification attempts.

Step 5: Create your remediation roadmap

Generate implementation plan

Ask ISMS Copilot to structure your action plan:

"Based on this gap analysis, create a remediation roadmap for ISO 27001 certification target date of [date]. Include: Phase breakdown, key milestones, resource requirements, dependencies, risks, and deliverables for each phase. Organize as: 1) Foundation (policies, scope, risk methodology), 2) Risk assessment and control selection, 3) Control implementation, 4) Internal audit and refinement, 5) Certification readiness."

Assign ownership and accountability

Define who does what:

"For each gap remediation action, suggest: responsible role (who executes), accountable role (who approves), required support/consulted parties, and informed stakeholders. Create RACI matrix format for a [company structure]."

Track progress and update status

Create a tracking mechanism:

"Design a gap closure tracking template including: Gap ID, Description, ISO clause/control reference, Priority, Status (Open/In Progress/Completed), Owner, Target date, Actual completion date, Evidence location, Blocker/issue notes. Format as spreadsheet structure."

Step 6: Address common gap categories

Documentation gaps

Most common in new implementations:

"I have documentation gaps for: [list areas like risk methodology, Statement of Applicability, security procedures]. For each, provide: 1) Template structure, 2) Mandatory content requirements, 3) Example content for [industry], 4) Evidence auditors will request. Prioritize by audit criticality."

Technical control gaps

Common in under-resourced IT environments:

"We have technical gaps in: [logging and monitoring, access control, encryption, backup testing, vulnerability management]. For each, suggest: 1) Minimum viable implementation for ISO 27001, 2) Recommended tools/solutions for [budget level], 3) Configuration requirements, 4) Evidence collection methods."

Process gaps

Often overlooked until audit:

"We lack formal processes for: [incident response, change management, access reviews, internal audit]. For each process, provide: 1) Minimum required procedure, 2) Key roles and responsibilities, 3) Frequency/triggers, 4) Documentation requirements, 5) Common audit questions."

Evidence gaps

The difference between implementation and demonstrable compliance:

"For these implemented controls [list controls], what evidence will auditors request to verify effectiveness? For each control, specify: evidence type (logs, reports, records, screenshots), collection frequency, retention period, and where to store for audit access."

Pro tip: Start collecting evidence immediately, even before full implementation. Auditors need to see controls operating over time (typically 3-6 months for Type II audits). Retroactive evidence collection is often impossible.

Step 7: Validate with stakeholders

Review with technical teams

Ensure technical gaps are accurately assessed:

"I need to validate these technical control gaps with our engineering team. Create a technical gap review presentation covering: current state assessment, identified gaps, proposed solutions, implementation effort, timeline, and required resources. Make it suitable for technical audience."

Present to leadership

Get executive buy-in for remediation budget:

"Create an executive summary of this ISO 27001 gap analysis including: current compliance level (percentage), critical gaps requiring immediate attention, certification timeline and gate milestones, budget requirements (consulting, tools, personnel), business risks of gaps, and ROI of certification. Target: 5-minute presentation for C-level."

Align with compliance/audit teams

If you have existing compliance programs:

"We already comply with [SOC 2 / HIPAA / PCI DSS]. Map our existing controls to ISO 27001 requirements. Which existing controls satisfy ISO requirements? What incremental work is needed vs. starting from scratch? What can be leveraged?"

Step 8: Compare against industry benchmarks

Understand typical maturity levels

Calibrate expectations:

"For a [industry] company at [maturity stage: startup, growth, enterprise], what does typical ISO 27001 readiness look like? What gaps are common vs. concerning? Where should we be stronger than average given our [risk profile / customer requirements / data sensitivity]?"

Identify industry-specific considerations

Get context for your sector:

"For [healthcare / fintech / SaaS / manufacturing] companies implementing ISO 27001, what additional controls or enhanced implementations are typically needed beyond baseline? What regulatory intersections exist (HIPAA, PCI, GDPR)? What do auditors scrutinize most heavily in this industry?"

Common gap analysis mistakes and how to avoid them

Mistake 1: Self-assessment bias - Overestimating current implementation maturity. Solution: Ask ISMS Copilot: "What questions should I ask to objectively verify control implementation vs. existence? What evidence proves a control is operating effectively?" Then test your assumptions.

Mistake 2: Checkbox mentality - Marking controls as implemented without evidence. Solution: For each control you mark "implemented," ask: "What evidence demonstrates this control is operating effectively? What would an auditor request? Do I have this evidence readily available?"

Mistake 3: Ignoring context - Assessing controls without considering organizational context. Solution: Upload your ISMS scope and ask: "Given our scope [upload], which controls are applicable? Which can be legitimately excluded? What's the justification?" Avoid applying irrelevant controls.

Mistake 4: Underestimating remediation time - Assuming gaps can be closed quickly. Solution: Ask: "For gaps requiring [policy creation / process implementation / technical deployment], what realistic timelines exist including review cycles, approvals, training, and evidence collection?" Add 30% buffer.
