Digital Forensics
Forensic investigation and analysis of digital evidence.
What this assessment covers.
Digital evidence is fragile, and its integrity depends on how it is collected, handled, and analysed. DERISK’s Digital Forensics service provides meticulous investigation and analysis of digital evidence to support incident response, legal proceedings, internal investigations, and regulatory compliance.
Our forensic experts use court-admissible methodologies to preserve, collect, examine, and report on digital evidence from workstations, servers, mobile devices, and cloud environments. We maintain a strict chain of custody throughout the process, ensuring findings are defensible and reliable.
Whether you need to investigate a suspected breach, support litigation, or understand the full scope of a security incident, DERISK delivers thorough forensic analysis with clear, actionable reporting.
How we test.
A structured, expert-led methodology from initial reconnaissance through to real-time reporting and remediation guidance.
- 01
Evidence Identification & Preservation
We identify relevant sources of digital evidence and take immediate steps to preserve them — creating forensic images, securing logs, and preventing any alteration of original data.
- 02
Chain of Custody Establishment
We establish and maintain a rigorous chain of custody documenting every interaction with the evidence, ensuring its integrity and admissibility in legal or regulatory proceedings.
- 03
Forensic Collection & Imaging
We create forensically sound copies of disks, memory, mobile devices, and cloud data using industry-standard tools and methodologies that preserve the original evidence.
- 04
Examination & Analysis
We analyse the forensic evidence to reconstruct timelines, identify artefacts of compromise, recover deleted data, and uncover the full scope of activity on the systems in question.
- 05
Reporting & Expert Testimony
We deliver a detailed forensic report with findings, methodology, and supporting evidence, and can provide expert testimony if required for legal or regulatory proceedings.

Digital Forensics questions.
When do we need digital forensics rather than incident response?
Incident response is about containing and recovering. Forensics is about establishing exactly what happened, when, and by whom — to a standard that holds up in legal, regulatory or HR proceedings. Serious incidents usually need both.
Is the evidence admissible?
Acquisition follows forensically sound procedure with documented chain of custody, verified imaging and hashing throughout, so findings can withstand scrutiny. Confirm specific jurisdictional requirements with your legal counsel during scoping.
What sources can you analyse?
Endpoints, servers, cloud and SaaS audit logs, network telemetry, and mobile devices, depending on what is available and in scope. Act quickly — many log sources have short retention windows.
How is confidentiality maintained?
Investigations are run by a restricted team under NDA, evidence is held in controlled storage, and reporting goes only to the recipients you nominate.
Often scoped together.
