In their own words
Diligent Audit
Diligent Audit is software for planning, carrying out and reporting internal audits. It links audit plans with enterprise risk, supports risk prioritization and offers natural-language analysis of data. AuditAI can carry prior audits forward, prepare evidence requests, send follow-ups, run control tests and help prepare reports. The platform monitors controls for gaps and exceptions, with actions held for review, and can summarize findings for board-ready reports. Diligent says consequential AI actions need human approval; recommendations can be explained or overridden, and actions are recorded in an audit trail. Connectors are described for SAP, Oracle and Concur. Audit materials describe mobile apps and offline fieldwork, while the product listing identifies mobile apps as web-only. Security features listed by Diligent include FedRAMP and DoD IL5 authorization, encryption and role-based access controls. The product supports templates, evidence collection, findings, remediation tracking and continuous monitoring. Pricing is available on request; there is no free plan. Diligent says most organizations transition from manual processes within three months using onboarding and pre-built workflows.
