Digital Forensics

Independent findings. Understandable explanations.

We explain digital evidence and technical opinions in a form you can use to make informed legal or organizational decisions. Our reporting connects the questions asked to the examination performed and the conclusions the evidence supports.

UNDERSTAND THE EVIDENCE

Show the evidence, the reasoning and the limits of the opinion.

A useful expert report lets the reader follow the path from the instructions and source material to the conclusion. We explain digital evidence in clear terms, distinguish observed records from interpretation and address the uncertainties that matter to the question being asked.

01 / THE EXAMINATION

Clarify the role before the examination

Technical assistance, an investigative findings report and an independent opinion for a proceeding are different assignments. We discuss the intended audience, forum, questions and materials before defining the work. Counsel identifies applicable procedural requirements; the expert role and any opinion must remain within the relevant expertise and instructions.

For an opinion intended for court, independence is part of the assignment, not an optional style of writing. The requirements vary by forum. As one example, British Columbia Supreme Court civil rules expressly distinguish an expert’s duty to assist the court from advocacy for a party.

02 / THE EXAMINATION

Use instructions that leave room for the evidence

The brief should distinguish established facts, allegations, assumptions and disputed points. Asking whether the records support an explanation is more useful than asking an expert to prove it. Relevant contrary material and earlier reports should be identified so the examination does not begin with an incomplete account.

Where the starting material is incomplete, the instruction can identify a staged question: what can be said now, which assumption matters most and what additional evidence could change the answer? That is often more useful than asking for a categorical opinion before the relevant sources are available.

03 / THE EXAMINATION

Keep observation and opinion separate

A report may establish that a record contains a timestamp or account identifier. What that record means is a further analytical step. We explain the event source, corroboration and assumptions before expressing an inference about activity or attribution. The language of the conclusion should not be stronger than the evidence supporting it.

An explicit chain of reasoning helps counsel assess the opinion. It should be possible to identify the observed record, the meaning assigned to it, the corroboration or assumption used and the resulting conclusion. A reader should not have to infer those steps from a screenshot or an unexplained software label.

04 / THE EXAMINATION

Make the reasoning open to examination

The report and supporting records should identify the material examined, material not examined, methods, relevant tool versions or settings, and significant limitations. The purpose is not to overwhelm the reader with technical output; it is to make the important steps understandable and capable of being evaluated.

Technical detail should be proportionate to the issue. A contested interpretation may require focused validation or comparison with another method. Tool output is not self-proving, and a limitation affecting the conclusion should appear with the reasoning rather than being hidden in an appendix the reader may never consult.

05 / THE EXAMINATION

Prepare for questions, not advocacy

Where retained for testimony, we explain the technical basis of the report and address questions within the expert scope. Independence includes recognising contrary findings, acknowledging missing evidence and revisiting an opinion when material new information changes its foundation. A polished report does not guarantee admissibility or a litigation result.

Testimony preparation can clarify terminology, source references and the way exhibits explain a sequence. It should not change the substance to favour a party. Where a question falls outside the evidence or expertise, the appropriate answer may be that the available work does not support an opinion on it.

RELEVANT SOURCES

Follow the evidence across the relevant sources.

The useful sources depend on the question, lawful scope and what remains available. Collection and examination are agreed for the particular matter.

Instructions and assumptions

These define the question and the factual basis supplied to the expert. They should be distinguished from facts independently established in the examination.

Collected digital evidence

Acquisitions, native records and exports provide the evidential material. Their provenance, coverage and limitations determine what can be tested.

Examination records

Notes, methods, settings and relevant verification work help explain how the reported observations were obtained.

Supporting and contrary material

Related records, other expert reports and known alternative explanations may affect the conclusion and should not be omitted merely because they are inconvenient.

Forum requirements

Counsel identifies the applicable rules, dates and report requirements. These differ by proceeding and are not satisfied simply by using the title expert report.

HOW WE WORK

A defined question. A documented examination.

We connect the scope, sources and methods to the result you need, with the limits of the evidence made clear.

  1. Define the role and questions

    Agree the intended use, scope, materials, assumptions and procedural dependencies.

  2. Examine the relevant evidence

    Document methods and observations and identify material gaps.

  3. Test and explain the opinion

    Evaluate alternatives and connect each conclusion to its evidence and assumptions.

  4. Report and support the proceeding

    Deliver the agreed report and supporting material; prepare testimony within the retained scope where required.

BEFORE WE BEGIN

Give us the context. Preserve the source.

A clear first discussion helps us identify a useful scope. Use the contact page for an initial inquiry, not to upload evidence or credentials.

  • Identify the forum, audience, intended use and relevant deadlines.
  • Provide neutral questions and distinguish facts, allegations and assumptions.
  • List the evidence, prior reports and known contrary or missing material.
  • Clarify whether the instruction is for technical findings, independent opinion, testimony or a combination.

COMMON QUESTIONS

Understand the limits
before you begin.

Can DFI guarantee a conclusion that supports our case?

No. The conclusion must follow the evidence. A supported negative finding or an unresolved question may be the correct result.

Is every forensic report an expert report for court?

No. A technical findings letter may serve a different purpose. The intended use and applicable procedural requirements should be established at the outset with counsel.

Can an expert rely on an existing export or another examiner’s work?

Potentially, but its provenance, scope and limitations must be understood. The report should identify what the expert examined personally and the basis for any reliance on other material. Further source access may be necessary.

What if new evidence changes the opinion?

The change should be assessed and communicated rather than concealed. Counsel and the expert should address any required supplementary reporting or other procedural steps for the forum.

Technical references and further reading

General educational guidance. Source-specific capabilities and available records require assessment; legal authority and procedure should be addressed with counsel.
