The eDiscovery Managed Services Landscape
The global eDiscovery market surpassed $18 billion in 2025 and continues to grow at a compound annual rate exceeding 8%, driven by escalating data volumes, cross-border litigation complexity, and tightening regulatory requirements. Managed service providers have become indispensable partners for legal teams that need predictable costs, scalable capacity, and specialized expertise without building large in-house discovery operations.
What Managed Service Providers Actually Do
Unlike pure software vendors, eDiscovery MSPs take operational ownership of the discovery workflow. A typical engagement covers:
- Collection & Preservation
- Forensic acquisition from custodian devices, cloud platforms (M365, Google Workspace, Slack), and enterprise systems, with defensible chain-of-custody documentation.
- Processing & Analytics
- De-duplication, near-duplicate identification, email threading, and early case assessment using technology-assisted review (TAR) and generative AI tools.
- Managed Document Review
- Staffing and supervising review teams—often combining onshore attorneys with offshore reviewers—under quality-controlled workflows with continuous recall/precision monitoring.
- Production & Presentation
- Generating privilege logs, redaction sets, and load files in court-specified formats, plus trial preparation support.
