Comparison Table
FTI Consulting
enterprise_vendorGlobal business advisory firm offering forensic and litigation services including document redaction for investigations.
Redaction log plus reason-code driven rationale tied to privilege and disclosure review decisions.
FTI Consulting is structured to handle document review lifecycles where redaction choices must map to specific review rationale, including redaction reason codes and a retained redaction log. The delivery model fits legal teams that need consistent application across teams and case stages, including legal hold review workflows. Automation is typically used to reduce manual redaction effort, while human review oversight addresses edge cases like embedded text, scanned pages, and layout inconsistencies.
A key tradeoff is that outcomes depend on case staffing and input quality, including clear instructions for what qualifies as privileged information and what qualifies as confidential business information. This is a strong fit for matter-based review cycles such as discovery production preparation, where turnarounds require controlled review workflow and traceable decisions. It is less suited for organizations that expect fully self-serve redaction throughput without managed review oversight.
- +Redaction coding and reason tracking that supports defensible decision trails
- +Managed review operations that coordinate privilege review and disclosure review
- +Process controls suited to consistent redaction across large case document sets
- +Support for both native and rendered documents during review workflows
