Our process

The same four steps, every time.

Free Consultation

One conversation on an encrypted line, at no charge. We establish what you actually need to know — which is often not the question you arrived with — and whether it can be answered lawfully.

Written Scope

What is in scope, what is deliberately out of it, what methods will be used, what it costs and what it cannot promise. You sign it before any money changes hands.

Field Work

Documented as it happens, not reconstructed afterwards. Observation logs are contemporaneous, devices are imaged before examination, every document recorded with source and date.

Report & Debrief

An executive summary you can act on, an evidence index your lawyer can work from, and an explicit statement of what could not be established. Delivered to named recipients only.

Most people arrive describing a situation rather than a service. That is normal — working out which discipline answers your question is our job, and the first conversation is free.
