How we work

A defensible process from first call to final report.

Every matter follows the same four-stage discipline. The evidence is preserved before it is examined, and the report is written to be read by a court.

Intake

Scope, authority and legal constraints. We confirm the mandate, the jurisdictions and the questions the evidence must answer.

Preservation

Write-blocked acquisition, hashing and chain-of-custody. Nothing is examined before it is preserved.

Analysis

Forensic examination, timeline reconstruction, subject and network analysis. Findings are traced to the artefact.

Reporting

Plain-language report, expert statement and testimony. Every conclusion is reproducible and defensible.

Evidence handling

The chain is the case.

A forensic finding is only as strong as the chain that proves it. We preserve, hash and document every artefact from the moment it is identified — so the conclusion survives cross-examination.

  • Chain of custody — every transfer, seal and access is logged.
  • Write-blocking — originals are never altered; analysis runs on verified copies.
  • Hashing — SHA-256 / SHA-1 manifests prove integrity at every stage.
  • ISO/IEC 27037 — identification, collection, acquisition and preservation.
