Trullion is the execution layer
between your GRC and your data

Internal audit teams still spend 60–80% of their time on fieldwork, across scattered spreadsheets and PDFs.
Your GRC tells you what to test. Trullion handles the rest.

Policy summarization

Condense policies and control narratives into clear insights, saving hours of manual review.

Data matching

Compare and reconcile data across thousands of documents, in seconds.

Evidence collection

Instantly surface key details from contracts, invoices, and ledgers – with full traceability to the source.

Built for audit-grade precision

Centralized workflows

No more scattered spreadsheets or lost email attachments – evidence collection and test outputs live together.

Fully built-in audit trails

Every change is automatically logged. See exactly how results were produced, ensuring transparency and compliance from start to finish.

Scalable testing

Move beyond sampling to full-population coverage without adding headcount. Upload your documents, and automation does the heavy lifting.
