If damages, economic loss, and deposition strategy are central, Duff & Phelps provides damages and economic loss frameworks tailored for expert testimony and litigation strategy.
Validate defensibility for fraud, compliance, or regulatory matters

FTI Consulting fits when damages modeling must combine forensic accounting with digital evidence so technical findings become litigation narratives.
Common Mistakes to Avoid
Common selection errors come from mismatching delivery style to evidence needs, under-scoping complex workstreams, or assuming every provider offers managed forensic testing end-to-end.
Assuming every provider delivers end-to-end forensic testing
Forensic Focus is guidance-driven and supports retaining qualified forensic experts with workflow clarity and courtroom considerations rather than managed forensic lab delivery. Teams that need end-to-end evidence development should look to providers like Kroll, Mandiant Services, Magnet Forensics, Deloitte, or PwC for investigation delivery.
Overlooking evidence access and coordination requirements
Mandiant Services can require customer-side access coordination for highly technical engagements, which can constrain speed when access is delayed. Kroll and FTI Consulting also require clear early-stage scoping to prevent multi-workstream coordination friction when multiple evidence threads must run in parallel.
Choosing a provider that is strong in tools but not report-ready outputs
Magnet Forensics supports examiner tooling and repeatable pipelines, but it still requires trained examiners to configure processing and interpretation correctly. For courtroom-ready narratives, Kroll and FTI Consulting emphasize expert witness reporting and testimony preparation tied to legal scrutiny.
Scaling a finance dispute without finance-first forensic structure
Duff & Phelps is optimized for damages and economic loss analysis with deposition and cross-examination preparation, which many generalist forensic teams may not replicate. For disputes that combine finance with technical evidence, Exiger and FTI Consulting connect evidence-grade digital work to financial tracing or litigation narratives.
How We Selected and Ranked These Providers
We evaluated each service provider on three sub-dimensions that directly map to delivery outcomes: capabilities with a weight of 0.4, ease of use with a weight of 0.3, and value with a weight of 0.3. The overall rating is the weighted average of those three sub-dimensions calculated as overall = 0.40 × features + 0.30 × ease of use + 0.30 × value. Forensic Focus separated from lower-ranked options because it combined very high ease of use at 9.7 with strong capabilities at 9.4 through a case and tool guidance hub plus reporting and courtroom considerations. That pairing reinforced usability for investigators who need practical workflows and defensible documentation patterns rather than only broad investigation capacity.
