Cyber Forensics & Investigation

Digital Forensics

Disk, memory and log forensics that reconstruct the intrusion timeline and preserve the chain of custody.

Every engagement includes manual validation, a two audience report and free re-testing.

What this actually is

Digital forensics is the discipline of answering what happened, in a way that survives someone trying to discredit the answer.

That means imaging before analysis, hashing everything, documenting every step, and never working on the original. Skipping those steps is how findings get thrown out.

We examine disks, memory, logs and cloud artefacts, and reconstruct the timeline to the level of detail the situation demands.

What we go after

  • Forensic imaging with hash verification
  • Disk and file system analysis including deleted artefacts
  • Memory analysis for in-memory malware and credentials
  • Log and event correlation across sources
  • Cloud and SaaS audit artefact examination
  • Anti-forensics and log tampering detection
  • Timeline reconstruction
  • Chain of custody documentation 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

  • Forensic images with verification hashes
  • Detailed findings with supporting artefacts
  • Reconstructed timeline of events
  • Chain of custody records
  • Expert report suitable for legal proceedings

Who needs this

Organisations investigating an incident, a dispute or suspected misconduct where the findings may be challenged.

How long it takes

One to four weeks depending on evidence volume.

Standards this satisfies

  • ISO 27037
  • ISO 27042
  • NIST SP 800-86
  • 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

The machine has been rebuilt. Is anything recoverable?

Often more than people expect. Backups, cloud audit logs, network telemetry and email archives frequently survive a rebuild. We will tell you honestly what can and cannot be established.
