--- title: "ISO 27001 vs SOC 2: Evidence Requirements Compared" summary: "While SOC 2 focuses on technical system controls, ISO 27001 requires evidence of a functioning Information Security Management System (ISMS). This guide explains the exact documentation and screenshots auditors expect for both frameworks and how automation bridges the gap." publishedAt: "2026-04-23" author: "Screenata Team" image: "/static/iso-27001-vs-soc-2-evidence-requirements-compared.jpg" tags: ["ISO 27001", "SOC 2", "Compliance Automation", "Audit Evidence", "ISMS", "Annex A"] category: "Compliance" featured: false --- ISO 27001 and SOC 2 audits both require proof that your security controls actually work, but they ask for that proof in fundamentally different ways. SOC 2 auditors want to see system configurations, access logs, and application screenshots proving specific Trust Services Criteria are met. ISO 27001 auditors want documentation proving you have a functioning Information Security Management System (ISMS) governing those controls. While many teams try to reuse their SOC 2 evidence for ISO 27001 certification, they quickly realize that API-based checks alone do not satisfy ISMS requirements. Automating evidence collection across both frameworks requires capturing both the technical system state and the management processes behind it. ## What is the Fundamental Difference Between ISO 27001 and SOC 2 Evidence? SOC 2 evidence proves a technical control is operating effectively at a specific point or period in time. ISO 27001 evidence proves you have a management process that identifies risks, implements controls, and continuously improves over time. If we look at access control as an example, the difference in auditor expectations becomes obvious. For SOC 2 (CC6.1), the auditor wants a screenshot of your AWS IAM dashboard showing that MFA is enforced, plus a sample of user access reviews. They care about the technical reality of the system. For ISO 27001 (A.5.15), the auditor wants the Access Control Policy document, the risk assessment that justified the policy, the management review minutes approving it, and *then* the technical screenshot showing it is enforced. You can pass a SOC 2 audit by having secure systems. You will fail an ISO 27001 certification if your systems are secure but your management documentation is missing. ## How Do ISO 27001 Annex A and SOC 2 Controls Overlap? Despite the difference in management philosophy, the actual technical evidence you collect for SOC 2 maps heavily to the ISO 27001 Annex A controls. If you capture the right artifacts, you can satisfy both frameworks with a single piece of evidence. | Control Area | SOC 2 Criteria | ISO 27001:2022 Annex A | Shared Evidence Acceptable | | :--- | :--- | :--- | :--- | | **Logical Access** | CC6.1, CC6.2 | A.5.15, A.5.16, A.5.18 | Screenshots of IdP settings, MFA enforcement toggles, RBAC matrices, and user access review logs. | | **Change Management** | CC8.1 | A.8.32 | Pull request approvals, CI/CD pipeline deployment logs, and Jira ticket workflows showing testing before release. | | **Vulnerability Management** | CC7.1 | A.8.8 | Penetration test reports, automated vulnerability scan results, and remediation tracking tickets. | | **Vendor Management** | CC9.2 | A.5.19, A.5.21 | Vendor security questionnaires, SOC 2 reports collected from third parties, and vendor risk matrices. | | **Incident Response** | CC7.3, CC7.4 | A.5.24, A.5.26 | Incident response plans, post-mortem reports, and tabletop exercise documentation. | ## Can You Reuse SOC 2 Screenshots for an ISO 27001 Certification? Yes. The technical proof is identical. When you capture a screenshot of your GitHub branch protection rules to satisfy SOC 2 CC8.1, that exact same screenshot works for ISO 27001 A.8.32 (Change Management). The catch is the Statement of Applicability (SoA). ISO 27001 requires you to explicitly state which Annex A controls apply to your organization and which do not, justified by a formal risk assessment. If you hand an ISO auditor a folder of SOC 2 screenshots without mapping them to your SoA and risk treatment plan, they will reject the submission. The technical evidence must be contextualized within the ISMS. In practice, maintaining two separate evidence libraries is a mistake. It leads to version control issues and massive audit fatigue. Instead, structure your evidence around your actual business systems rather than control IDs. A single PDF evidence pack showing a new developer's onboarding flow can be tagged to both CC6.2 and A.5.18. When the auditor asks for proof, you export the system-based evidence pack and provide the mapping document. ## What ISO 27001 Evidence Cannot Be Automated with GRC Tools? Where traditional compliance automation stops is the boundary between APIs and human processes. GRC platforms like Drata and Vanta are excellent at pinging AWS to verify encryption at rest or checking GitHub for branch protections. But ISO 27001 relies heavily on management processes that do not live in APIs. Traditional tools struggle to automate: 1. **Management Review Minutes:** The formal meetings where leadership reviews ISMS performance and resource allocation. 2. **Risk Assessment Methodologies:** The actual scoring, evaluation, and treatment decisions for asset risks. 3. **Internal Audit Results:** The independent checks of your own ISMS before the Stage 2 external audit occurs. 4. **Application-Level UI Controls:** Custom admin panels, internal HR tools, or legacy systems that lack public APIs but still require access control validation. For these areas, teams usually fall back to manual screenshot collection and spreadsheet tracking. This is why relying purely on API integrations leaves a massive evidence gap for ISO 27001 compared to SOC 2. You need tools capable of workflow recording and UI-level capture to document these manual management steps and custom applications. By deploying AI agents that can record application workflows and capture visual evidence, you can bridge the gap between technical system configurations and the ISMS documentation that ISO 27001 auditors expect. ## Learn More About ISO 27001 Evidence Automation For a complete guide to managing your ISMS documentation and Annex A requirements, see our guide on [automating ISO 27001 evidence collection](/resources/blog/how-to-automate-iso-27001-evidence-collection), including how to capture application-level controls that traditional tools miss.
