Category overview
What digital forensic investigation means
Digital forensic investigation involves the identification, preservation, examination and interpretation of information from devices, accounts, files, communications or online sources. The purpose is to answer defined questions while protecting the integrity and context of the material.
Not every digital enquiry requires full forensic acquisition. Some matters may involve open-source research, metadata review or targeted technical examination. The method should match the question, authority and evidential requirement.
Important: C3I does not guarantee a particular finding, legal outcome, recovery, arrest, conviction or commercial result. Suitability and scope must be assessed before engagement.

Common decision situations.
The examples below describe information problems, not guaranteed findings or automatic reasons to investigate.
A device or account may contain relevant evidence
Authority, ownership, access rights and preservation must be assessed before examination.
Online activity needs to be documented
Public-source or authorised research can capture relevant content with date, source and context.
A communication is disputed or suspicious
Headers, metadata, file properties and surrounding records may help assess authenticity or origin.
Material may be needed for legal review
Documentation and preservation should be planned with counsel and evidential requirements in mind.
Methodology
A controlled path from concern to report.
Specific methods vary, but the underlying discipline remains consistent.
- 1
Confirm authority
Establish ownership, consent, legal basis, scope and authorised decision-makers.
- 2
Stabilise the evidence
Avoid unnecessary access and identify appropriate preservation actions.
- 3
Document the source
Record device, account, file, date, condition and collection context.
- 4
Acquire or collect
Use a method proportionate to the question and evidential requirement.
- 5
Examine and validate
Analyse artefacts, compare sources and test alternative explanations.
- 6
Report limitations
Explain what the evidence supports, what remains uncertain and which factors could affect interpretation.
Engagement outputs
What an authorised client may receive.
Actual deliverables depend on scope, evidence, intended use and the agreed engagement terms.
Preservation record
Documentation of the source, handling steps and relevant identifiers.
Technical findings
A clear explanation of observed artefacts and their possible significance.
Evidence index
An organised schedule of files, captures, extracts or other reviewed material.
Expert briefing
A non-technical explanation for authorised decision-makers or legal advisers.
Frequently asked questions
Questions to resolve before work begins.
No. Recovery depends on the device, storage method, encryption, overwriting, backups, system activity and the time elapsed. No responsible provider should guarantee recovery.
C3I requires appropriate authority, ownership, consent or legal basis. Technical ability does not replace lawful authority.
It is the documented history of how evidence was identified, collected, transferred, stored and examined. The required level depends on the intended use.
Ordinary use can alter logs, timestamps, sync state and other information. Preservation and examination methods aim to minimise and document changes.
Screenshots may be useful, but they can lack source context and are easier to dispute. Stronger documentation may include URLs, timestamps, metadata, exports, hashes or independent captures.
Any expert role would depend on the examiner's qualifications, the work performed, the legal context and a separate assessment. It should not be assumed automatically.

Confidential consultation
Define the question before selecting the service.
Initial assessment considers objective, sensitivity, authority, feasibility, urgency and appropriate scope.
Safety and legality: Immediate danger or suspected criminal emergencies should be reported to the police or appropriate public authority. C3I will not accept work requiring unlawful access, harassment, impersonation or other prohibited conduct.
