Digital evidence and security
Los Angeles Computer Forensics
Computer, mobile and cloud evidence for Los Angeles commercial disputes, litigation and security incidents. Start with the facts you need to establish.
Start with the question the evidence needs to answer
A disputed file can have a history across an editing workstation, shared storage, a contractor laptop and a cloud account. Collecting one copy may preserve its contents without explaining who accessed it or which version was delivered. GDF helps Los Angeles businesses and counsel connect those sources to the question that matters.
Computer forensics examines activity and artifacts. eDiscovery organizes authorized collection and delivery for legal review. Expert witness work evaluates and explains technical findings. These services may share evidence, but they need different scopes and deliverables. We identify the work required before asking you to transfer devices or confidential records.
The work proceeds through identification, extraction, preservation, interpretation and documentation of electronic evidence. Each step needs a record of the method and any limitations. Recoverability depends on encryption, device condition, deletion behavior and available account access. No examiner can guarantee that every lost or deleted record will be recovered.
Los Angeles litigation support
Evidence priorities in Greater Los Angeles
For an LA matter involving project media, intellectual property or a distributed business team, identify the organizations that control the records as well as the people using them. A contractor may hold the source project while a client has only a rendered deliverable. Preserve both where authorized, and record the relationship between them. For litigation, counsel identifies the venue and applicable requirements; GDF supplies technical work, not legal advice.
Scope the work to the matter
Computers, drives and mobile devices
Define whether the question concerns file presence, access, transfer, deletion or communication. Preserve the device state and collection record. An acquisition hash helps identify a data set; it does not establish authorship or prove that every relevant source was collected. Avoid running recovery utilities or resetting a device before discussing preservation.
Project files and disputed media
Keep native files, source recordings, project dependencies and available revision history. A compressed messaging copy may lack metadata or details present in the original. Distinguish authenticity of the media from the identity of its creator, and examine surrounding communications before attributing an edit or disclosure.
Employee departures and access disputes
Compare endpoint artifacts with identity, sharing, mailbox and repository records around the agreed dates. Account activity does not automatically identify the person responsible. Document time zones, retention gaps and alternative explanations before presenting a timeline to management or counsel.
Security testing and incident evidence
Separate a live incident from a planned penetration test. During an incident, coordinate preservation with containment and recovery. For testing, agree written authorization, target ownership, excluded systems, test windows and stop conditions. Vulnerability assessment findings and demonstrated attack paths should be reported distinctly.

Arrange an evidence or security consultation
Begin with a nonconfidential summary, the parties for conflict review, the relevant dates and any immediate deadline. Identify who controls the devices and accounts, and whether anything is scheduled for deletion or reuse. Confirm authorized scope and a protected transfer method before sending evidence. Do not send passwords or ship equipment without arrangements.
Frequently asked
Questions about Los Angeles engagements
Can the work include contractors and records outside Los Angeles?
Yes, where access and collection are authorized. Map each custodian to the relevant devices, tenants and service providers. A local business address does not determine where its electronic records reside.
Can you recover every deleted file?
No. Storage reuse, encryption, device damage and deletion behavior can prevent recovery. An examiner assesses the available sources and explains what could and could not be obtained.
Should we collect everything before contacting an examiner?
Not necessarily. Unplanned copying can omit metadata, overlook linked records or change useful evidence. Describe the sources and urgency first so preservation and collection can be scoped deliberately.
