How to choose the right compliance audit software

Choosing compliance audit software comes down to matching features with your team’s needs and future growth. Use these steps to guide your evaluation of compliance audit software options.

‍

1. Start with your pains and desired outcomes. Identify what you need to fix—manual processes, limited resources, or shifting compliance requirements.
2. Define your decision criteria. Set clear benchmarks like time savings, frameworks supported, and auditor experience.
3. Inventory your stack and data flows. Ensure the platform has native integrations for cloud, identity, code, asset, and ticketing systems.
4. Validate automation coverage. Map controls to available signals and confirm evidence updates are frequent and complete.
5. Assess auditor workflows and test. Involve your auditors early by granting them scoped access to the platform. Verify that they can trace evidence back to the source system, and track whether the tool reduces back-and-forth during the audit process.
6. Model scale and total cost of ownership. Project performance and costs across users, assets, and frameworks, and test pricing tiers and SLAs.

Compliance audit software FAQs

What is compliance audit software?

Compliance audit software centralizes controls, automates evidence collection, and streamlines collaboration with auditors. It helps teams track readiness, map controls across frameworks, and generate reports, reducing manual effort and improving consistency during audit preparation and fieldwork.

How does it reduce audit prep time?

By integrating with cloud, identity, and ticketing systems, compliance audit platforms automatically collect evidence and monitor controls. Tasks, ownership, and reminders keep work moving, while reusable mappings minimize rework across frameworks to cut time spent on manual screenshots and exports.

Which frameworks are typically supported?

Common coverage includes SOC 2, ISO 27001, PCI DSS, HIPAA, GDPR, and others. Many platforms also support additional standards via mappings or templates so teams can scale from a single framework to a broader compliance portfolio without starting from scratch.

How should we evaluate integration needs?

List your critical systems and data sources, then verify native connectors exist and capture the required artifacts. Confirm your evidence refresh cadence, scope of signals, and how gaps are flagged. Strong integration coverage minimizes manual uploads and reduces audit risk over time.
