Data Collection &
Forensics

Talk to an Expert

Execution You Can Defend

Forensics is not about owning tools. It’s about controlling evidence under scrutiny. Our
teams operate globally with certified expertise, documented methodology, and reproducible
processes designed to withstand regulatory challenge and courtroom examination.

    • 50+

      Certified Forensic Experts

      Global in-region teams with advanced industry certifications.

    • 100 TB

      Collected

      Enterprise-scale collections with zero data loss and full chain-of-custody.

    • 70+

      Jurisdictions Supported

      Defensible workflows aligned to global privacy and data sovereignty laws.

Controlled. Documented.
Review-Ready.

Collection is the foundation of the matter. If it’s sloppy, everything downstream suffers.
Our four-phase model ensures evidence integrity, minimizes disruption, and delivers data ready for
immediate legal action.

  • STEP 1

    Define and Lock the Perimeter

    Before anything moves, we control the scope.

    • Identify custodians, systems, and timeframes through structured legal scoping
    • Apply defensible holds via Google Vault, Microsoft Purview, or equivalent platforms
    • Document preservation decisions at the matter level
    • Map cross-border risk including GDPR, LGPD, PIPL, and regional privacy requirements

    Result:

    Evidence secured before exposure risk begins.

  • STEP 2

    Deploy the Right Collection Method

    Not all data is equal. Neither are collection methods.

    • Execute source-native cloud exports (Vault, Purview, Slack Discovery API)
    • Perform Physical, Full File System, or Advanced Logical mobile extractions using Cellebrite, Magnet Axiom, Oxygen, and Elcomsoft
    • Conduct remote agent-based collections or controlled kit deployments
    • Perform on-site forensic imaging for complex servers, RAIDs, and enterprise systems using EnCase, FTK, and Nuix

    Result:

    Metadata-intact, defensible evidence capture — without unnecessary overcollection.

  • STEP 3

    Preserve Context, Not Just Files

    Evidence stripped of context loses power.

    • Preserve threading, timestamps, attachment relationships, and sender/recipient metadata
    • Maintain custodian-separated tracking for chain-of-custody clarity
    • Capture cloud-linked attachments via Graph API and equivalent mechanisms
    • Produce detailed validation reports including hash verification and documented exceptions

    Result:

    Evidence that tells the full story, not a disconnected export.

  • STEP 4

    Deliver Review-Ready Data

    Collection isn’t complete until analysis can begin.

    • Standardize data into review-ready formats
    • Apply deduplication and initial filtering
    • Load directly into Amplify™ Suite of Tools
    • Eliminate unnecessary vendor handoffs

    Result:

    Evidence moves directly into strategy.

Why Lineal

Forensics Built for Scrutiny

Many providers can extract data. Few can defend it under cross-examination. We combine certified forensic expertise, platform-level fluency, and disciplined execution to deliver collections that stand up under pressure.

  • Evidence-First Thinking

    We don’t treat collection as a technical checkbox. We treat it as controlled evidence acquisition. Scope decisions are informed by downstream impact, regulatory risk, and litigation strategy.

  • Platform-Level Mastery

    M365 is not Slack. Slack is not Google. Encrypted messaging is not email. We maintain tested, source-specific workflows for each environment, accounting for export nuances, API limitations, and audit traceability.

  • Reproducible, Documented Execution

    Every collection follows documented methodology with full chain-of-custody reporting, validation logs, and exception tracking. Nothing is improvised. Nothing is undocumented.

  • Advanced Mobile & Device Capability

    Certified examiners perform Physical, Full File System, and Advanced Logical extractions across iOS, Android, and macOS environments. We recover deleted artifacts, application data, encrypted content, and system-level evidence with defensible rigor.

Technology in Action

The Tools Are Powerful.
The Execution Is What Matters.

Enterprise-grade tools only deliver value when deployed with discipline. Our forensic operations integrate
directly into processing and review — eliminating friction and preserving context.

  • Amplify™ Suite of Tools + Relativity

    Lineal’s proprietary engine for modern legal data, built natively within Relativity environments. Amplify™ tools like ChatCraft, BotDetector, Images, and PrivFinder handle threaded chat reconstruction, system message filtering, visual content classification, and privilege detection without leaving the review platform. Data moves from collection through processing and into review with full operational visibility and no vendor handoffs.

  • Microsoft Purview eDiscovery

    Lineal manages Purview collections end-to-end for clients who need defensible M365 data without burdening internal IT. We handle legal hold, search, and export across Exchange, OneDrive, SharePoint, and Teams, with advanced chat processing and modern attachment handling via the Graph API.

  • Google Vault

    Lineal coordinates Vault-based holds and Takeout exports to capture complete Google Workspace datasets, delivering defensible collections with audit trails for Gmail, Drive, Chat, and Meet. We handle administrative searches, exports, and full or targeted user data downloads end-to-end.

  • Cellebrite

    Lineal’s certified forensic examiners deploy Cellebrite onsite or remotely to preserve defensible mobile evidence without disrupting custodian workflows. We perform physical, full file system, and advanced logical extractions, even from locked, encrypted, or damaged devices, using Cellebrite Premium for access to the latest models and targeted application collections in BYOD scenarios.

  • Nuix

    Lineal deploys Nuix in secure environments, including air-gapped networks, with processing profiles tuned to each matter. We support forensic processing and investigation across large, complex datasets, disk images, email archives, registry files, and mobile extractions, with email threading, relationship mapping, and advanced filtering for fraud and regulatory investigations.

Excellence and
Innovation

  • “Regulators gave us 90 days and 12 million documents. Lineal’s team reduced the review population by 97% and met the deadline without a single extension request. That kind of precision under pressure is why they handle our most sensitive matters.”

    General Counsel, Top 10 Global Bank

  • “We eliminated first-pass review entirely on our largest IP matter. Over 95% of the population was reduced before a reviewer touched a single document, and every decision was defensible. That changed how our entire legal department thinks about review.”

    VP of Legal Operations, Fortune 100 Pharmaceutical Company

  • “We used to send every large matter to an outside vendor. Now we handle it internally with Lineal’s team and technology sitting behind our operation. Our partners see it as a value-add for clients, and it has become a meaningful revenue line for the firm.”

    Managing Partner, Am Law 100 Firm

  • “Our previous provider treated RelativityOne like a hosting platform. Lineal treated it like the foundation of our entire legal operations strategy. The migration took two weeks. The transformation of how our teams use the platform is still compounding a year later.”

    Head of Litigation Technology, Am Law 100 Firm

  • “We had cycled through two providers in three years. Lineal was the first partner that embedded into our operations instead of just processing our data. We now have rea-time visibility into spend, predictable timelines, and a legal ops function our board takes seriously.”

    Chief Legal Officer, Fortune 20 Corporation

  • Lineal has become an essential extension of our litigation team. Their expertise, responsiveness, and technology-driven approach consistently elevate the quality and efficiency of our matters.
