Service
Digital forensics
Forensically sound collection and analysis of phones, computers, email and cloud accounts, preserving evidence so it can be relied upon later.
Overview
How digital forensics works.
Evidence on a phone or computer is fragile. Messages can be deleted, apps updated, accounts closed — and a careless copy can change the very data you need to rely on.
GFIR collects digital evidence using forensically sound methods and documented chain of custody, so it can be trusted by lawyers, courts and investigators. We then analyse it to answer specific questions: what was communicated, when, by whom, and what happened on the device.
Whether the evidence supports a fraud claim, an employment dispute or an incident investigation, the aim is the same: findings that are accurate, reproducible and clearly explained.
Signs you may need this
- Key evidence exists only on a phone, laptop or online account
- You need to prove what was said, sent or done — and when
- A device may have been accessed or tampered with
- Your lawyer has asked for evidence to be preserved properly
- Data may soon be deleted, overwritten or lost
Every item is sealed and logged in a chain-of-custody record.
Findings are explained in a clear expert report.

Preserve the evidence
Devices and accounts are captured using forensic tools, with every step logged in a chain-of-custody record.
- 03
Analyse
We recover, filter and examine the relevant data — messages, files, logs, location and app activity.
- 04
Report findings
A clear expert report sets out what was found, how, and what it does and doesn't show.

Questions
About digital forensics
Do I need to give you my phone?+
Usually for a short time, or we can arrange collection in person. In some cases a remote or cloud-based collection is possible.
Can deleted messages be recovered?+
Sometimes. It depends on the device, the app, encryption and how much time has passed. We'll assess this before you commit.
Will the evidence stand up in court?+
Our process is designed to be defensible: documented methods, verified copies and a full chain of custody. Admissibility is ultimately for the court.
Is my personal data safe?+
We only examine what's relevant to the agreed questions, store data securely and delete it according to our retention policy.
