Frequently asked questions

What is forensic document review?

It is document review supported by forensic methodology — material is prepared from soundly collected sources with preserved metadata, deduplication and document families, so the review and any production are reliable and defensible.

Can you reduce our review volumes?

Yes. Through deduplication, de-NISTing, date and keyword filtering and custodian organisation we reduce volumes proportionately before review to control cost and time.

Do you export to Relativity?

Yes. We produce Relativity-ready load files, metadata, extracted text and native files, and support comparable review platforms.
