ISO 27001 Gap Analysis Spreadsheet

Preparing for ISO 27001 certification starts with understanding where you stand today. This comprehensive gap analysis spreadsheet maps every control from ISO 27001:2022 Annex A and helps you systematically evaluate your organization's current security posture against each requirement. Rather than hiring expensive consultants for an initial assessment, this template empowers your team to conduct a thorough internal review and identify exactly which controls are fully implemented, partially implemented, or missing entirely. The spreadsheet covers all 93 controls across the four ISO 27001:2022 categories: Organizational Controls (37 controls), People Controls (8 controls), Physical Controls (14 controls), and Technological Controls (34 controls). For each control, you will find the control reference number, control title, a plain-language description of what the control requires, fields to document your current implementation status, evidence of compliance, identified gaps, and recommended remediation actions with priority levels and estimated effort. The built-in scoring system automatically calculates your overall readiness percentage and breaks it down by category, giving you a clear visual dashboard of where your strengths and weaknesses lie. This is invaluable for communicating compliance progress to leadership, prioritizing remediation work, and estimating the effort required to reach certification readiness. Whether you are a startup pursuing your first ISO 27001 certification or an established company preparing for a recertification audit, this gap analysis template provides the structured framework you need to turn compliance from an overwhelming project into a manageable, step-by-step process.
