Diligent Internal Audit: cost, fit and limits
Diligent Internal Audit is an audit management product made by Diligent Corporation that manages audits, risks and findings in one hub, adds ACL Analytics and internal controls, and uses an agentic audit assistant to draft requests, test controls and write reports.
What to know first
Diligent Internal Audit sits inside Diligent's wider governance and GRC portfolio, which also includes board, risk and compliance products. The audit page promises centralized audit management, risk-aligned planning, continuous control monitoring and board-ready reports, with an audit agent that coordinates work but asks for human approval. Pricing and hosting are not shown, and the savings figures on the page are the vendor's own.

Who Diligent Internal Audit is best for
Audit departments already on Diligent
The same vendor sells board management and enterprise risk products, so audit findings and board reporting can move through connected tools, if the organization is already a customer.
Teams buried in PBC follow-ups
The audit agent drafts evidence requests, sends follow-ups, escalates overdue items and assigns remediation owners, which targets the chasing that fills audit calendars.
Audit leaders reporting to boards
The page says the agent turns findings into board-ready reports from a single prompt, which suits chief audit executives who present to an audit committee.
Teams wanting analytics in the same hub
ACL Analytics and natural-language queries on full data sets let non-specialist auditors run anomaly detection without a separate analytics tool.

What Diligent Internal Audit does
- Audit agent for engagement setup
- Rolls forward prior audits and drafts project structures in minutes, so an engagement starts without days of manual setup. Reviewers can adjust the structure before work begins.
- Request management
- Drafts evidence requests, sends follow-ups, escalates overdue items and assigns remediation owners automatically, shrinking the time spent on PBC lists. Audit staff keep ownership of each request and its due date.
- Control testing and reporting
- Executes control tests, drafts documentation, flags exceptions for review and builds remediation plans by control owner before turning one prompt into a board report. Findings stay linked to the controls tested.
- Continuous control monitoring
- Agentic AI watches controls around the clock and flags gaps and exceptions before they escalate, with every action held for the team's review. Audit staff decide whether each flag needs follow-up.
- Risk-aligned planning
- Audits connect to enterprise risk so the audit plan adapts when risk changes, and AI-accelerated risk assessments rank by likelihood, impact and velocity. Planning therefore follows current risk, not last year's list.
How Diligent Internal Audit handles your data
The Diligent Internal Audit page states that every consequential action requires human approval, that recommendations are explainable and over-rideable and that every step is captured in a complete, traceable audit trail. It does not state certifications, hosting regions, retention or whether customer data trains models, and the vendor's policy on those points was not checked for this product page. Diligent's privacy page describes the personal data the company collects through its websites and features and how it is used. Ask for the trust documents covering the audit product itself.
Where Diligent Internal Audit falls short in practice
- Figures are vendor claims. The page quotes about $10,000 saved per audit and a 70 percent cut in request management time, with no method. Treat them as marketing until your own pilot shows the numbers.
- No certifications or hosting on the page. A buyer sees analyst rankings but no security attestation or region on the audit page, so a security review needs a separate request. Ask for the trust package early.
- A portfolio sale. Diligent sells audit next to board, risk and compliance products. Ask which licenses the audit agent requires, and whether it needs the wider Diligent One platform.

Alternatives to Diligent Internal Audit
Diligent Internal Audit: common questions
What does the Diligent audit agent do?
The audit page says it rolls forward prior audits and drafts project structures, drafts evidence requests and follow-ups, executes control tests, drafts documentation and flags exceptions, and turns a prompt into a board-ready report. Every consequential action requires human approval.
Can the audit agent act without approval?
The page says agentic does not mean autonomous. Every consequential action requires human approval, recommendations are explainable and over-rideable, and every step is captured in an audit trail. Ask which actions count as consequential and whether that list is configurable.
Is ACL Analytics part of Diligent Internal Audit?
Diligent's navigation lists Internal Audit, ACL Analytics and Internal Controls together under the Audit group, and the audit page promises advanced analytics with natural-language queries. Ask whether ACL Analytics is bundled or licensed separately in your quote. Ask for the licensing split.
Does Diligent publish a price for internal audit?
No. The audit page shows a demo form with name, phone and company fields and no plan or price. Request a quote that lists modules, users, agent usage and implementation, and compare it with the savings figures the page quotes.
Which analysts rank Diligent?
The page says Diligent has been named a Leader by Chartis, Forrester, Gartner, IDC and Verdantix. Those are the vendor's statements about analyst reports, not a statement about security or accuracy, so ask which report covers the audit product you are buying.
