Frequently asked questions
What does 'defensible' mean here?
That every step is documented, repeatable and proportionate, so the process and the resulting data can withstand challenge from an opponent, court or regulator.
Can you scale to large matters?
Yes. The same defensible method applies to high-volume datasets, with early case assessment and filtering to keep review proportionate.
Do you provide chain-of-custody records?
Yes. Continuous chain of custody, hashing and collection notes are standard across the workflow.
