What this actually is

Phones hold more evidence than laptops now. Messages, location history, app data, deleted content still sitting in unallocated space, and cloud backups that outlive the device.

We extract and analyse Android and iOS devices for investigations, disputes and incidents, using methods that preserve integrity.

Modern device encryption limits what is possible, and we will tell you what is achievable for a given model and OS version before you commission the work rather than after.

What we go after

  • Logical and file system extraction where supported
  • Application data analysis including messaging platforms
  • Deleted content recovery where recoverable
  • Location history and device usage timeline
  • Cloud backup analysis with proper authorisation
  • Malware and spyware detection on the device
  • Chain of custody throughout

How we run it

  1. 01

    Preserve

    First priority is evidence integrity. We image and hash before anyone starts changing things.

  2. 02

    Contain

    Stop the bleeding without destroying the trail. These two goals fight each other, and experience is what balances them.

  3. 03

    Investigate

    Timeline reconstruction across endpoint, network, cloud and identity, until we can say what happened and when.

  4. 04

    Report

    Findings written to survive scrutiny from a regulator, an insurer or a court.

  5. 05

    Harden

    The root cause fixed, not just the symptom, so the same door is not open next quarter.

What you receive

  • Extraction report with verification hashes
  • Analysed findings relevant to the question asked
  • Device usage and location timeline
  • Chain of custody records
  • Expert report where proceedings are likely

Who needs this

Organisations investigating misconduct or data theft, and legal teams needing device evidence.

How long it takes

Three days to two weeks per device.

Standards this satisfies

  • ISO 27037
  • NIST mobile forensics guidance
  • Indian Evidence Act

Why it matters

After an incident there are three questions that have to be answered, and none of them can be answered well without preparation: when did it start, what was actually taken, and is the attacker still inside. Regulators, insurers and customers all ask them, and vague answers are treated as bad ones.

The most common problem we meet is that the evidence is already gone. Systems rebuilt, logs rotated, machines rebooted in good faith before anything was preserved. How the first hour is handled decides whether the rest of the investigation is possible.

Choose how you want this delivered

Most of the price difference between quotes comes down to this one choice, and it is rarely explained. Pick one to see what it covers, what it suits and what it costs you.

Terms, contacts and access agreed in advance, with a guaranteed response time. The value is not the discount, it is that the first day is spent responding rather than negotiating a contract while an intruder is still active.

Choose this when

  • Any organisation holding regulated or personal data
  • Boards or insurers asking about incident readiness
  • You want the mobilisation clock to start in minutes, not days

Effort and cost

An annual fee, with unused hours typically usable for proactive work. The cheapest reduction in breach cost available.

What we look for, and keep finding

These are the classes of problem this work exists to surface. Not every engagement finds all of them, but these are the ones that turn up often enough to be worth naming.

  • Evidence destroyed by the response

    The most common problem we meet. Systems rebuilt, logs rotated, machines rebooted before anything was preserved. What could have been established is often gone before we arrive.

  • Incomplete timeline

    Knowing the breach happened but not when it began. Without an accurate first access, scope cannot be bounded and notification obligations cannot be answered honestly.

  • Unclear data exposure

    The question every regulator and customer asks: what was actually taken. Answering it needs artefacts that only exist if logging and retention were adequate beforehand.

  • Chain of custody failures

    Evidence handled in a way that will not survive challenge. If there is any prospect of proceedings, how the first hour was handled decides whether the findings are usable.

  • Persistence left behind

    Recovery declared complete while access remains. We look specifically for the second and third mechanism, because a competent intruder does not rely on one.

Who runs your engagement

Investigators who have given evidence

Investigations are led by people who have produced findings that survived challenge. Our founder advises law enforcement and has trained officers in cyber crime investigation, so the method is one that police and courts recognise.

Questions we get asked

Can you unlock a locked phone?

Sometimes, depending on model, OS version and lock type. We assess feasibility before you commit budget, and we will not promise what the hardware does not allow.

Do we need the employee's consent?

For a company-owned device with a clear acceptable use policy, usually not, but this is a legal question and we will flag where you should take advice before we proceed.
