A Structured Model for
High-Stakes Matters
Investigations fall apart without structure, which is why we apply a disciplined, repeatable framework that surfaces
facts quickly and delivers clear, defensible findings. Backed by deep experience, industry-leading technology, and our
own award-winning systems, we move with precision and speed—adapting to the demands of your matter while
keeping the investigation focused, efficient, and aligned with your goals.
-
STEP 1
Define the Exposure
Before data moves, we define the risk.
- Identify allegation scope, relevant actors, and business systems
- Map jurisdictions and data residency constraints
- Establish documentation protocols from day one to ensure evidence requirements are met and provable
- Lock down preservation across cloud, mobile, and enterprise platforms
- Help manage and ensure business continuity and data integrity while minimizing commercial disruption
- Manage ongoing costs and risks
Result:
A clearly defined investigative perimeter with legal defensibility intact.
-
STEP 2
Targeted Evidence Acquisition
We collect what matters — not everything.
- Execute forensic collection across M365, Google Workspace, Slack, Teams, WhatsApp, mobile devices, and structured systems
- Separate custodians and sources for clean chain-of-custody
- Preserve chat threading, cloud-linked attachments, and metadata integrity
Result:
High-integrity datasets ready for analytical interrogation.
-
STEP 3
Analytical Acceleration
This is where investigations differentiate from standard review.
- Apply AI-driven clustering and automated culling to reduce irrelevant volume
- Reconstruct conversations across platforms
- Identify key actors, communication patterns, and timeline inflection points
- Surface behavioral anomalies and coordination signals
Result:
A narrowed universe of high-risk communications and events. Fast.
-
STEP 4
Findings & Reporting
Data is useless without structured conclusions.
- Produce regulator-ready document sets
- Build communication maps and event timelines
- Identify involved actors and escalation paths
- Prepare defensible production packages and remediation documentation
- Help track progress to enable focus, prioritization and improved effectiveness of advisors
Result:
Clear findings that executives and regulators can act on.
Why Lineal
