Corporate eDiscovery Programs, Source Mapping and Recurring Matters

Corporate eDiscovery That Never Starts From Zero

A new matter should not mean rebuilding the discovery process from scratch. Global Digital Forensics, which serves Fortune 1000 companies and their outside counsel, builds one repeatable program around your systems, your people and your budget. The source map, the responsibility matrix and processing on software we own carry from matter to matter, so preservation, collection and production run the same way every time.

Why Corporate Discovery Costs Repeat Themselves

In most companies the same questions get answered again for every matter: which systems hold the records, who administers them, what the retention settings are and who is allowed to pull data. Each time the answers are rebuilt from scratch, the collection is broader than it needs to be, the review set is larger than the dispute warrants and the vendor invoice reflects the volume rather than the case. The legal department pays for the same learning curve twice a year.

We fix that by documenting responsibilities once. The responsibility matrix identifies the corporate data owner, the IT administrator, the technical work GDF performs and the supervising legal reviewers, and it states who approves scope, who receives status reports and how population counts, validation samples and exceptions are handled. Technical flags route likely privileged and sensitive material to the right reviewers before anything is released. The next matter starts from that record instead of from a blank page.

Is your legal department about to answer those questions from scratch again? Describe the systems and the matter to a senior examiner and we will outline the responsibility matrix on the first call.

Technical methods and scope

Coordinate Preservation Once and Reuse It Every Matter

Recurring matters are far easier to manage when custodians, system owners, contracts and collection responsibilities are documented before the next request arrives. GDF helps legal operations and IT establish that structure, so a new matter builds on the organization’s existing source knowledge rather than repeating the initial planning under deadline pressure.

The corporate workflow states the activation and support arrangements, the processing and hosting features, the staff responsibilities and the escalation contacts in the proposal. Availability, source support and response milestones are confirmed for the actual engagement, and because GDF owns its software, the processing and hosting plan is scaled to your matter volume rather than imposed by a platform’s pricing tier.

Technical Findings the Legal Department Can Act On

GDF collects and analyzes the technical record: the existing files, the communications, the access and deletion events and the relevant database entries. Each finding names the system it came from, the custodian, the date range and the method used, so the legal department can brief outside counsel, answer a regulator or release a hold without a second round of questions.

Our reports describe what the systems contain and how the material was collected, written so an executive can follow them and an opposing examiner can retrace every step.

Send the custodians and the deadline and the first call sets the collection plan.

Source Maps That Make the Next Matter Cheaper

A corporate source map shows where the records live before a request arrives, which lets the legal department direct IT precisely and focus preservation on the systems that matter. Our forensic practice works with computers, email, databases and cloud records every day, and we help legal operations and IT document the systems a recurring discovery program depends on.

The map can include Microsoft 365 tenants across subsidiaries, shared SharePoint sites, collaboration services adopted by individual business units, legacy databases with no API access and employee owned devices covered by company policy. Documenting ownership, retention and the collection path for each source makes later preservation decisions faster and more consistent, and it gives in house lawyers something concrete to point to when the adequacy of a search is questioned.

Coordinate Legal, IT and Privacy From the Preservation Stage

We coordinate legal requests, IT operating requirements and privacy review from the moment a hold is contemplated. Counsel defines the legal scope, IT manages the systems and the access, and the responsible privacy team evaluates the handling of personal information under the requirements that apply to the data, whether those arise from GDPR, CCPA or sector rules.

Collection minimization follows what the source and its query controls can actually do. Where out of scope material arrives with a collection, we record it with its access and retention controls and route it to segregation, privilege review or production filtering, so the privacy team sees exactly what was handled and how.

Describe the sources and the production format, and a senior specialist will map the collection.

Three Ways to Split the Discovery Work

Fully managed

When the legal department needs capacity rather than another project to run, we coordinate source identification, hold documentation, collection, processing, hosting and production, from the first hold notice to the final set. Legal leadership receives agreed status reports and a final package with custody records. This model suits matters that cross business units, agencies or international sources, where the internal team cannot absorb the technical work.

Hybrid insourcing and outsourcing

A hybrid engagement preserves the tasks your team already performs well, such as hold notices, custodian communications, early assessment or first pass review. GDF handles the agreed cloud collection, processing, review infrastructure, technical privilege flags and production preparation, and your reviewers work inside the set we build. Responsibilities are written into the statement of work so nothing falls between the two teams.

Internal platform use with specialist support

A capable internal discovery team can keep project control and use the platform features confirmed in its proposal for holds, collection and early analytics, and bring GDF in for the sources that defeat ordinary tools, such as SQL databases, encrypted mobile devices or unusual cloud APIs. The scope names the supported feature, the specialist task and the escalation arrangements. Call (800) 868-8189 to discuss which model fits your department.

Methodology

From Your Corporate Sources to Production in Four Steps

Map custodians and business systems

We translate requests, interviews and system knowledge into a corporate source map with custodians, retention and data types, built once and maintained across matters.
Preserve the approved records

We apply the preservation approach your lawyers approve and document owners, dates, scope changes and exceptions across the organization, so every hold can be explained later.
Collect and process the relevant data

We select supported methods for each system, verify transfers and reconcile extraction and processing exceptions with the responsible source owner, using GDF owned tools to remove duplicate and system files before review.
Deliver the agreed review or production package

We check the package against the agreed review or production specification and retain the supporting audit record, so the legal and operations teams can account for every item.

Evidence commonly examined

Corporate evidence sources we review

Custodian and system inventories identify the business owners and the records included in scope. Microsoft 365 and Google Workspace supply the corporate suite records, messaging and collaboration sources preserve the conversations and related files that survived retention, and computers, phones and file shares add the endpoint and departmental data that never reached a central system. Databases and structured business systems require documented selection and extraction, and the collection, processing and exception logs record the technical work and the items left unresolved.

What you can expect

Your corporate discovery record and deliverables

The data map and scope record identify corporate sources, custodians and responsibilities. The method logs document collection and processing across the included systems, the reconciliation report explains counts, transformations, exceptions and unavailable records, and the validated package supports the agreed review or production workflow and the team receiving it.

Legal operations teams that want these deliverables standing ready for the next request can call (800) 868-8189 and talk through which engagement model fits before the next hold is issued.

Frequently asked

Scope, Pricing, Platforms and Subsidiaries

What should we define before corporate eDiscovery work begins?

Map the custodians, the business systems and the internal responsibilities, then coordinate preservation with the legal department and the people who administer each source. We help you build that record once so it serves every later matter.

What determines the price of corporate eDiscovery?

Sources, volume, hosting duration, review scope and production needs shape the cost. GDF owns its software, so processing and hosting are scaled to the matter, and we provide an itemized scope with recurring charges and change approvals before work starts.

Can you work with the review platform our department already uses?

Yes. Tell us the platform, the formats and the tasks your team is keeping, and we confirm compatibility, transfer methods and responsibilities before anything is collected.

What if a preservation or production deadline is already close?

Call (800) 868-8189 with the deadline, the data sources and the current status. We discuss availability, priorities and a realistic sequence of work before you commit to anything.

Can the program cover subsidiaries and international sources?

Yes. The source map can span Microsoft 365 tenants across subsidiaries, collaboration services adopted by individual business units and sources held outside the United States, and the privacy team approves how personal data from each jurisdiction is handled before collection begins.
