Reactive Cybersecurity Services

Digital Forensics Investigation

Establish what happened, when and how, based on evidence handled with care.

Overview

Our digital forensics service examines endpoints, servers, storage media, cloud environments and other evidence sources to reconstruct events. We investigate attacker activity, program execution, persistence and data access, maintaining integrity verification and chain-of-custody records throughout.

Business objectives

  • Reconstruct an accurate timeline of events
  • Determine how access was gained and what was done
  • Identify data that may have been accessed or taken
  • Preserve evidence for internal, legal or regulatory use

Why it matters

Decisions after an incident, from notification to disciplinary action, depend on facts. Forensic analysis turns raw artifacts into findings you can rely on and defend.

Common challenges we address

  • Need to know exactly what an attacker accessed
  • Internal investigations into suspected misuse
  • Evidence required for legal, HR or insurance processes
  • Conflicting accounts of what happened

Scope and key activities

  • Forensic acquisition of disks, memory and logs
  • Integrity verification (hashing) of evidence
  • Chain-of-custody documentation
  • Operating system artifact analysis (for example Windows, Linux and macOS)
  • Memory analysis
  • Cloud and email audit log analysis
  • Timeline reconstruction
  • Malware triage
Methodology

Our approach

Work starts with an assessment of your needs and a written scope. Pricing follows that scoping and sizing.

  1. IdentifyAgree investigation questions and the evidence sources that can answer them.
  2. PreserveAcquire evidence with forensic methods, verify integrity and document custody.
  3. AnalyzeExamine artifacts and build a correlated timeline.
  4. ConcludeAnswer the investigation questions and state confidence and limitations.
  5. ReportProvide a clear report suited to its audience.

Frequently asked questions

Can your findings be used in court?

We follow accepted evidence handling practices, including integrity verification and chain-of-custody records. Admissibility is determined by the relevant legal process, so involve your legal advisors early.

What should we do before you arrive?

Avoid using, rebooting or reinstalling affected systems where it is safe to wait, preserve logs and record what you observed and when.

Do you investigate cloud environments?

Yes. We analyze audit logs and configurations from the cloud and email platforms in scope.
