The thesis

Manual work looks at a sample. AI agents look at everything.

Judgement stays human, we give the auditor a full X-ray, not a sample.

Traditional audit

Sample-based and periodic

  • ✕Examines a sampleThe issue may be exactly where nobody looked.
  • ✕Depends on interpretationTwo auditors, two conclusions.
  • ✕Outdated the next dayThe snapshot is only valid on extraction day.
NLC audit

Complete, traceable and continuous

  • ✓Processes 100% of the dataExceptions have nowhere to hide.
  • ✓Deterministic and traceableEvery finding carries its source evidence.
  • ✓Re-runnable at any timeAudit stops being a snapshot and becomes a film.
