How to Streamline Audit Processes
Top of Page
How can I make sure that the whole audit doesn't ground to a halt from infosec interruptions and GDPR hell?
To ensure that an Accounts Payable (AP) audit proceeds smoothly without being derailed by information security (InfoSec) restrictions and GDPR (General Data Protection Regulation) compliance issues, follow these strategies:
1. Pre-Audit Risk Assessment and Planning
-
Conduct a Pre-Audit Infosec Review:
- Work with your IT and legal teams to identify potential data access restrictions in advance.
- Assess which systems contain personal data and how access can be safely granted.
-
Define Data Scope Clearly:
- Ensure that auditors receive only the necessary data relevant to the AP audit (e.g., invoices, purchase orders).
- Avoid sharing personally identifiable information (PII) unless absolutely required.
-
Obtain Legal & Compliance Sign-Off Early:
- Involve the Data Protection Officer (DPO) and compliance team upfront to approve the scope and methodology of the audit.
- Secure necessary documentation (e.g., data processing agreements, NDAs) before the audit begins.
2. Use Secure Access Controls
-
Provide Read-Only, Time-Limited Access:
- Implement role-based access control (RBAC) to allow auditors to view data without modifying it.
- Use temporary logins with auto-expiration to prevent prolonged exposure.
-
Leverage Secure Portals and Data Rooms:
- Use GDPR-compliant cloud platforms (e.g., SharePoint, OneDrive, or dedicated VDRs) to share files securely with auditors.
- Ensure access is logged and monitored.
-
Tokenization and Data Masking:
- Mask or redact sensitive data (e.g., employee addresses, bank details) when providing reports.
- Consider tokenizing vendor details to protect identity while still allowing analysis.
3. Minimize GDPR Risks
-
Data Minimization Principle:
- Share only the data strictly necessary for audit purposes.
- Aggregate or anonymize data where possible before sharing.
-
Auditor GDPR Compliance Verification:
- Ensure the external auditors are GDPR-compliant and have policies in place to handle personal data securely.
- Request a data processing agreement (DPA) if personal data will be processed.
-
Secure Data Disposal After Audit:
- Establish policies requiring auditors to delete or return sensitive data post-audit.
- Obtain confirmation in writing that data has been deleted from their systems.
4. Establish Clear Communication with IT & Compliance Teams
5. Leverage Automation and Audit-Friendly Tools
6. Educate the Audit Team
7. Continuous Monitoring and Quick Resolution
- Real-Time Monitoring Tools:
- Use security monitoring software to detect unauthorized access attempts or data breaches during the audit.
- Regular Check-Ins:
- Schedule periodic meetings with auditors to ensure they have the access they need without compromising security.
By implementing these strategies, you can ensure a smooth audit process while maintaining compliance with InfoSec and GDPR requirements, avoiding unnecessary interruptions and potential penalties.

- Provides a clear chain of custody for audit documentation.
-
Improved Collaboration:
- Allows multiple auditors, finance staff, and compliance teams to collaborate without overwriting each other's work.
- Facilitates real-time updates and access to current versions.
-
Compliance Assurance:
- Helps ensure regulatory compliance (e.g., SOX, GDPR) by maintaining proper documentation history.
- Reduces the risk of errors or fraudulent alterations to financial records.
-
Faster Issue Resolution:
- Enables quick comparison of document versions to identify discrepancies.
- Provides rollback capabilities in case of errors or unauthorized changes.
