Expert Witness Testimony: Data and Forensics

What is expert testimony at iDS?

Expert testimony at iDS is the discipline every other discipline reports into. Our experts give expert opinions and serve in fact witness, PMK, 30(b)(6), and data neutral engagements, in both defense and plaintiff matters. Each report is written to withstand scrutiny, and the expert presents it and stands behind it in deposition and at trial.

What you receive

A report written to withstand scrutiny, and an expert who will present it and stand behind it on paper, in deposition, and at trial.

Neutral work

When the court needs an answer, not an advocate.

iDS experts serve as court-appointed neutrals, special masters for ESI discovery, and neutrals agreed on by both parties. We examine devices, mailboxes, cloud accounts, and databases under the terms of the order, and report what the data shows to the court.

Frequently asked questions

What kinds of testimony do iDS experts provide?

Expert opinions, fact witness, PMK, 30(b)(6), and data neutral engagements. Testimony is the discipline every other discipline reports into, from digital forensics and structured data to eDiscovery and damages. Every iDS discipline has a named expert behind it who will sit for the deposition.

Does iDS work for plaintiffs or defendants?

Both. Our case portfolio includes both defense and plaintiff matters. When the court needs an answer rather than an advocate, iDS experts serve as court-appointed neutrals, special masters for ESI discovery, and neutrals agreed on by both parties. Our CEO has served as special master on multiple occasions.

Will the expert stand behind the report at deposition and trial?

Yes. You receive a report written to withstand scrutiny, and an expert who will present it and stand behind it on paper, in deposition, and at trial. The question we start from is who will stand behind this opinion when it is challenged, and whether the method will survive the challenge.

Can an expert explain technical evidence so a judge or jury can follow it?

That is part of the job. Neutral reports are written for a reader who has never opened a forensic tool, and structured data findings come with visual exhibits a jury can follow. Our testimony covers method as well as result, and the expert who presents the opinion stands behind it.

What is at stake

The earlier you understand the evidence, the better the decisions that follow.

The evidence is abundant. But volume is not access. Access is not understanding. And understanding is not an expert opinion.

Increasingly, evidence is buried across devices, applications, databases, cloud systems, transactions, and other complex sources. It must be found, preserved, made accessible, understood, and interpreted in the context of the matter. And when expert testimony is required, that understanding must support an independent, defensible opinion.

When important evidence surfaces late, assumptions may already have become strategy. When it is identified, tested, and understood early, your team can build its strategy around what can actually be shown. This isn’t just for trial. It is also for TROs, letters rogatory, discovery requests, subpoenas, depositions, summary judgment, mediation, and arbitration.

You bring the legal expertise. We bring the evidence expertise.

iDS combines technical, analytical, and subject-matter expertise to help you move from evidence to understanding, and, when necessary, from understanding to opinion and testimony.

You know the law. We help you know the evidence.
