What is Forensic Auditing?
Forensic auditing is the application of accounting and investigative techniques to examine financial records for evidence of fraud or misconduct, in a form that can support legal proceedings. The distinction from a regular audit is purpose: a statutory audit forms an opinion on the accounts, a forensic audit builds a case.
When a forensic audit is triggered
The usual starting points are a whistleblower report, an unexplained variance that survives normal investigation, an anonymous allegation, or a regulator's enquiry. Sometimes the trigger is an insurance claim or a dispute between shareholders where financial facts must be established independently.
Scope is deliberately narrow. Rather than covering the financial statements as a whole, a forensic engagement targets specific transactions, a specific period, or specific individuals, and goes considerably deeper than a statutory audit would on the same population.
How forensic auditors work
The method combines document examination, data analysis, and interviews. Analytical techniques such as Benford's Law, duplicate detection, and timing analysis narrow a large population to the transactions worth examining individually. The audit trail then establishes who did what, and when.
Evidentiary discipline governs everything. Findings must be reproducible, the chain of custody over documents and data must be preserved, and conclusions must rest on what the evidence supports rather than what it suggests. Work that cannot withstand cross-examination has limited value however accurate it is.
Forensic Auditing and Supervizor
Forensic work depends on examining complete data, not samples. Supervizor's audit analytics solution applies investigative tests across the full ledger in a reproducible way. Investigation teams use it to:
- Run statistical anomaly tests including Benford analysis, duplicate detection and round-amount patterns across every entry
- Reconstruct transaction timelines linking postings, approvals and master data changes to specific users
- Produce reproducible evidence, with each test documented and re-runnable by a third party
