An ISO 9001 / ISO 27001 integrated audit can involve collecting evidence from various systems, examining hundreds of documents, and referencing the same controls in two standards. These manual processes are hard to control in an expanding organization. This is where AI adoption is helping audit teams overcome this challenge. The 2025 Deloitte Internal Audit Digital & Analytics Survey finds that 90% of internal audit functions now have digital and analytics plans aligned to their strategic goals and that generative AI technologies are becoming more common for enhancing audit quality and decision-making.
But AI isn't taking the place of auditors. Rather, it automates repetitive tasks like evidence collection, document categorisation and control monitoring, letting audit teams focus on assessing risks and verifying compliance. This guide walks you through the process of using AI for integrated ISO audits.
Key Takeaways (TL;DR)
AI can help with integrated ISO audits by eliminating repetitive tasks like evidence gathering, document management, the monitoring of controls, and audit reporting, but cannot replace the auditor's judgment.
Take one audit process or one ISO standard at a time, for example, ISO 27001, before implementing AI throughout your compliance program.
Select platforms that can connect with current business systems. Vanta, Sprinto, Drata, and AuditBoard are just a few of these solutions that offer continuous evidence collection, framework mapping, and AI-powered audit workflows.
A comprehensive management system and central compliance database is crucial. Incomplete, outdated, and fragmented records cannot be relied upon for insights from AI.
Get AI-driven insights to prioritize high-risk areas rather than manually reviewing each control. A machine learning model can detect the recurring findings, delayed corrective actions and the odd compliance patterns that warrant further attention.
Maintain human involvement in the audit life cycle. Auditors are responsible for confirming AI generated evidence, investigating findings, and final compliance decisions.
Set up governance before deployment, including what tools are approved, user responsibilities, data protection requirements and review procedures. There are some standards that offer guidance on the responsible governance of AI, including ISO/IEC 42001.
Assess success based on real-world metrics, such as how long it takes to prepare for audits, how much time is spent gathering evidence, how many manual tasks are eliminated and how long it takes to complete corrective actions.
How AI Supports Integrated ISO Audits
Automates Evidence Collection Across Business Systems
Getting evidence from various departments is one of the most difficult aspects of an ISO audit. Policies can be stored in SharePoint, user accesses in Microsoft Entra ID, tickets in Jira, and employee training records in an HR system.
Integrations and APIs with modern compliance platforms like Vanta and Sprinto allow them to get connected with these systems. Other than asking various teams to provide screenshots, they continually gather evidence and organize it for presentation to auditors. This significantly cuts down on manual follow- up, and helps to ensure that organizations are audit-ready all year long and not just before certification audits.
Maps One Control Across Multiple ISO Standards
There may be overlap in requirements in integrated audits. For instance, the document control, competency of employees and risk management are applicable for both ISO 9001 and ISO 27001.
Organizations can register one control to several compliance frameworks, rather than uploading the same evidence several times, in several compliance platforms. The framework and control mapping is supported in Vanta. This minimises overlaps and ensures consistency throughout an integrated management system.
Continuously Monitors Controls Instead of Waiting for Audit Season
Traditional audits rely on point-in-time reviews. AI-powered compliance solutions go the other way, by monitoring controls all year long.
For instance, when multi-factor authentication is turned off, a critical security setting is adjusted, or a policy expires, the platform can alert on that change before the next internal audit commences. There is continuous monitoring providing time for compliance teams to solve issues early.
Uses AI to Prioritize Risks Instead of Reviewing Every Record
It is difficult in large organisations to review each document individually. AI can assist by detecting any unusual patterns, recurring findings, and high-risk areas, which require further investigation.
Instead of getting into each access review or corrective action, auditors can focus on records that show evidence of missing evidence, repeated nonconformities, or lack of documentation identified by AI. This risk based approach enables more efficient audits, and enables the auditors to use their expertise where it is needed.
Improves Audit Documentation Without Replacing Auditor Judgment
Generative AI can create audit plans, summarize interviews, structure workpapers, and work up initial audit reports. Some platforms also check against the set standards before posting to auditors.
AI should not be used to decide on the effectiveness of a control, nor should it be used to decide if an organisation is compliant with an ISO standard. A range of decisions needs to be made based on professional judgment, interviews, sampling, and the validation of qualified auditors. Vendors themselves frame AI as a tool for assisting in the review and documentation of evidence and not replacing the audit profession.
What You Need Before Starting
A Mapped Integrated Management System
If your integrated management system isn't well documented, then AI can't map controls or suggest evidence. Identify and clarify how ISO standards relate to each other, what parts of the process they cover, and where there is evidence overlap before introducing AI.
For instance, organisations that are accredited with both ISO 9001 and ISO 27001 may find they have the same document control procedures, corrective action procedure and management review records. All these relationships can be mapped, enabling AI platforms to link one control to more than one standard, rather than one standard to one control. This minimizes duplicate evidence requests and makes it easy for future audits.
Centralized Compliance Data
AI works best when compliance information is collected in one place and well-managed. In the absence of these policies stored in shared drives, training data housed in HR software, and risk registers in spreadsheets, the AI delivery of results is less reliable.
This is often done through the development of a central repository for compliance that contains policies, previous internal audit reports, corrective actions, risk registers and supporting evidence. There are platforms such as Vanta and Sprinto that extend this concept by directly integrating with business systems to automatically capture evidence, and then all the evidence is correlated to audit controls.
Choose AI Audit Tools That Match Your Audit Scope
Not all AI platforms are ISO compliant. There are those that specialize in governance, and there are those that specialize in evidence collection, workflow automation, and/or internal audit management. The selection of a solution will depend on the standards that you are managing and the maturity of your compliance program.
Vanta and Sprinto are both popular solutions for ongoing monitoring and automated evidence collection, for instance, and Fieldguide uses AI to audit workflows and documentation. For larger companies, they can also explore audit and governance, risk, and compliance platforms that have AI capabilities like AuditBoard, Workiva, or ServiceNow GRC. Consider using software that not only offers AI capabilities but also aligns with your current systems, complies with your audit protocols, and enables you to audit and verify all AI-generated content.
Steps to Use AI in Your ISO Audits
Automate Compliance Evidence Collection
The first step is to integrate your AI audit tool with your existing data systems like Microsoft Entra ID, Google Workspace, Jira, Microsoft 365, AWS, Azure, or your HR system. Contemporary options such as Sprinto automate the process of evidence collection via API integration, rather than screenshots and manual uploads.
Centralize Document and Control Management
Do not introduce AI until there's a centralized place to store policies, procedures, risk registers, corrective actions and audit records. The better an AI platform can categorize documents, correlate them to ISO clauses and identify duplicate or obsolete documents, the more useful it is. A single policy can meet standards for multiple standards (e.g. ISO 9001 and ISO 27001 within integrated ISO audits). Multiple mapping of one document will cut back the work done and will help auditors to obtain supporting evidence easily.
Monitor KPIs and Controls in Real Time
Reviewing controls using AI biannually or annually is not a better approach than continuously monitoring compliance. There are plenty of platforms that operate governance and compliance and work real-time on security configurations, user access, training completion, and corrective actions. The system can alert the compliance team immediately if a control fails, such as if multi-factor authentication (MFA) is disabled, the team will be alerted.
Predict Risks With Machine Learning
Machine learning can analyze historical audit findings, incidents, and corrective-action data to identify recurring risk patterns. Tools such as TeamMate and AuditBoard offer documented AI capabilities that can support risk assessment and audit planning. However, these insights should guide auditor attention, not replace professional judgment or be confused with the rules-based compliance automation offered by platforms such as Vanta and Sprinto.
Generate Audit Checklists and Reports
With Generative AI, audit documentation preparation time can be reduced. It can prepare the first draft of audit reports, work papers, summarizations of interview notes and audit checklists from evidence. AI is already being used in platforms like Fieldguide to help document and manage audit work. But the auditor should always audit AI generated content and ensure the findings are accurate, complete and consistent with the applicable ISO standard before providing a report.
Enable Continuous Improvement
Use AI post-audit. Analyze any areas of nonconformity, any late corrective actions, and for any failures in the process, identify the long term trends. AI can also identify controls that are performing well and those that need greater supervision or training. The insights gained assist organisations in improving their ISO management system, in their future audits and in compliance with the continual improvement obligations, which are prevalent in many ISO standards.

Keeping Humans and Governance in the Loop
Keep Humans Responsible for Audit Decisions
Use AI to assist with evidence gathering, document review, and report generation. But it is always the auditor's responsibility to validate, confirm and approve the last audit report. It is in line with the ISO/IEC 42001 standard, which requires human oversight of AI systems for decision-making.
Establish AI Governance Policies
Make sure that you have a clear understanding of how you are going to utilize AI in your audit process before putting it to use. Develop policies for the use of AI tools, user responsibilities, access to data, and review protocols. Governance should also involve guidelines for managing confidential data, keeping records of AI-driven choices and tracking system performance over time.
Protect Sensitive Compliance Data
Many audit records include classified business information, employee records and security documents. When integrating an AI platform into your systems, check how data is collected, where the data will be used, and if customer information is used to train AI algorithms. Choose vendors that provide strong security controls, encryption, and transparent data-handling practices.
Limitations and Risks of AI in Auditing
AI Is Only as Good as the Data It Receives
AI is not a substitute for missing or incorrect compliance documentation. Without up to date policies, evidence is elusive, and control documentation isn't aligned, AI might provide inaccurate recommendations. Precise and accurate compliance data is critical for accurate results.
AI Can Produce Incorrect or Fabricated Information
Sometimes, generative AI models give inaccurate answers or even quote information that isn't there, a problem known as AI hallucination. This means that auditors should not blindly trust reports or summaries generated by AI without examining the supporting evidence.
Not Every AI Tool Is Built for ISO Audits
In some cases, GPTs can be used to create documents or provide summaries of text, but they are not intended to handle compliance evidence or audit processes. Organizations need to check if the platform offers features such as framework mapping, audit trails, role-based access controls, and integration with existing business systems.
Privacy and Regulatory Requirements Still Apply
Sharing sensitive business data or internal data handling policies within the public AI tools could lead to the exposure of information. Before implementing any AI, ensure that the provider's platform complies with your company's security, privacy and contractual protocols.
Practical Tips for Rollout
There is a gradual integration of AI that helps to reduce the impact on the organization. Do a small test, and then scale as you become more confident.
Begin with one or one ISO standard then expand to all integrated ISO audits.
Set clear goals for employing AI, whether it's streamlining the audit process or better data collection.
Select AI audit software that integrates with ISO management systems.
Preprocess and tidy compliance data prior to using AI tools.
Educate auditors and compliance teams about the proper and responsible use of AI.
Set up procedures for reviewing all AI-generated content, including a review by an auditor.
Regularly check performance and make adjustments to processes in the light of audit findings.
Regularly audit AI tools to see if they are still effective in meeting ISO requirements.
Common Mistakes to Avoid
Trying to Automate the Entire Audit Process
The best way for AI to provide value is by assisting with repetitive tasks, and not supplanting the entire audit workflow. Start with areas that provide near-term value such as collection of evidence or organization of documents and then expand AI throughout the audit program
Choosing AI Software Without ISO Expertise
While many AI platforms provide automation options, not all are specifically geared toward compliance management. Consider software that is capable of meeting your ISO standard requirements, will integrate with your current systems, and will deliver audit-ready evidence rather than just AI features.
Ignoring Data Quality Before Deployment
AI is frequently implemented in organizations without data cleaning. Lacking policies or having multiple policies with similar names and formats makes it difficult for AI to be accurate and also makes it more difficult to audit. Preparations to organize data, before implementation, result in more reliable outcomes.
Trusting AI Outputs Without Verification
While AI capabilities can summarize documents and generate reports, it can also mess up. Before any AI-generated checklist, finding or recommendation becomes a part of the official audit record, it should be compared with supporting evidence.
Overlooking Security and Vendor Risk
Evaluate the security strategies of the vendor, data retention policies, and compliance certifications before integrating AI into business systems. Knowing the place of data storage, its protection strategy and ability to train AI models is just as crucial as some of the automation features of the platform.
Skipping Employee Training
No matter how good the AI platform is, without having the employees ready to use it, the platform will not be of any use. Give practical training for auditors, compliance teams, and process owners to understand when to trust AI, when to challenge AI results, and how to use AI responsibly.
Start Small, Then Scale With Confidence
AI's most valuable applications typically start with one audit and then expand from there. For instance, platforms such as Vanta and Sprinto typically begin by automating evidence gathering for standards like ISO 27001 and then move on to other standards. Also, AI isn't enough to make an audit more reliable. No matter how automated an audit is, a well-functioning ISO management system, good compliance data, and experienced auditors will always make a difference in the quality of the audit. AI is just making those teams more efficient by cutting down on repetitive admin tasks and uncovering problems earlier in the audit process.
For organizations considering implementing AI to assist with compliance, the challenge should be tackled one at a time, with results monitored, and only expanded upon once successful. Cognixis can help organizations assess real-life AI scenarios that meet their compliance and operational objectives.
How can AI support integrated ISO audits?
AI can assist in automating the evidence gathering process, arranging compliance-related documents, tracking controls, and producing draft audit reports. It minimises manual effort and enables auditors to spend more time analysing findings and risk assessment.
Which ISO standards can AI audits cover?
AI can support audits for standards such as ISO 9001, ISO 27001, ISO 14001, and ISO 45001. It is particularly helpful for organizations with multiple standards that operate an integrated management system.
Can AI collect audit evidence automatically?
Yes. API integrations collect evidence on a continuous basis with platforms like Vanta or Sprinto that connect with cloud-based services, identity providers, and HR systems. But the auditor should still ensure that the evidence is complete and relevant.
Does AI replace human auditors?
No. AI helps to sort through the evidence and write reports, but auditors are still required to assess controls, interview the stakeholders and determine compliance.
What are the risks of using AI in auditing?
The risks are primarily: inadequate data quality, erroneous AI-generated results, privacy issues, and over-ambitious automation. These risks can be mitigated through human oversight and good governance.
How does ISO 42001 relate to AI in audits?
ISO/IEC 42001 offers a guideline for the responsible use of AI in governance. It supports organizations in creating policies for the proper use of AI in business processes, such as auditing, supporting human oversight, transparency, and accountability.
