Comparison Table
UnitedLex
enterprise_vendorUnitedLex delivers hosted eDiscovery, managed review, legal operations, and technology-assisted review services.
Staff-led ediscovery hosting that pairs review execution with monitoring for outside counsel workflows and spend context.
UnitedLex is a fit for organizations that want hosted case infrastructure paired with guided discovery and review operations, not just storage. Staffed workstreams coordinate discovery and document review across matters, and review quality checks help keep execution consistent when volume rises. Contract operations and outside counsel oversight use the same managed-service approach to standardize intake and monitor activity and spend.
A tradeoff is that the operational model demands tighter coordination on review protocols and governance so the team can execute consistently. UnitedLex is strongest when legal and legal operations need repeatable handoffs across litigations or recurring contract work rather than ad hoc hosting alone.
- +Staffed discovery and review coordination for consistent execution at high volume
- +Managed processes for document-heavy litigation support
- +Outside counsel workflow monitoring with analytics on activity and spend
- +Repeatable intake, routing, and review processes for recurring work
- –Execution depends on defined governance and review protocol alignment
- –Integration work can require more onboarding than self-serve hosting

Lighthouse
enterprise_vendorLighthouse delivers hosted eDiscovery, legal data processing, review management, and production support.
Predictive coding program support with documented seed, iterative training, and validation sampling.
Lighthouse fits legal departments and litigation support teams that need recurring ediscovery hosting operations, not just file storage. Hosted review workflows are paired with managed document processing for intake, conversion, OCR, and quality control so document collections arrive review-ready more consistently. For predictive coding programs, Lighthouse supports supervised relevance-ranking workflows with seed sets and iterative training that include validation sampling to document model performance.
A key tradeoff is that Lighthouse delivery relies on operational coordination for configuration and workflow handoffs, which can slow time-to-first-review if internal stakeholders move slowly. Lighthouse is a strong fit when matter workflow implementation must stay consistent across multiple custodians and repeated review cycles, such as ongoing investigations or frequent litigation updates.
- +Managed hosting reduces administration across repeated litigation review cycles
- +Document processing helps standardize review-ready collections for productions
- +Predictive coding workflows include validation sampling practices

Use the comparison table and detailed reviews above to validate the fit against your own requirements before committing to a tool.
How to Choose the Right Ediscovery Hosting
In ediscovery hosting, the real differences show up in how data is controlled across the lifecycle: whether custodians and case data land correctly, whether legal holds and exports run with predictable automation, and whether audit logs and RBAC are detailed enough to support your playbook.
Provisioning and RBAC for case workspaces
Why it matters
Provisioning and RBAC for case workspaces determine who can see what, from upload through export, without relying on manual workarounds. In ediscovery hosting, that control quality affects turnaround time and reduces the risk of mixing case data.
How to check
In a demo, ask for a role setup (e.g., read-only reviewer, admin, and upload-only) and then verify what each role can access in the UI and APIs. Create a small test workspace, add two users from different roles, and try an export and an upload to confirm the permissions boundaries.
Hold controls and evidence lifecycle actions
Why it matters
Hold controls and evidence lifecycle actions matter because hosting should keep legal hold state and evidence status aligned with case needs. If the workflow breaks across days, the hosting layer becomes the bottleneck.
How to check
Ask how hold state is represented (active, released, scoped) and show what happens to new uploads and existing evidence during a hold. Then run a short sequence in the sandbox: place a hold, upload a sample file, and demonstrate what changes and what remains locked.
Audit log detail for admin and data actions
Why it matters
Audit log detail for admin and data actions is what lets teams reconstruct who changed what and when across the hosted environment. In this category, a shallow log forces manual tracking and creates disputes.
How to check
Request an example audit log export and confirm it includes user identity, time, action type, and the specific object affected. In the demo, perform a permission change and an evidence action, then locate both events in the audit log.
Automation and API surface for repeatability
Why it matters
Automation and API surface for repeatability reduce human handoffs when cases move quickly or multiple matters run in parallel. Strong automation lets teams provision, monitor, and export consistently.
How to check
Ask for an API walkthrough showing at least workspace creation, evidence upload kickoff, and export job status. Then ask how you can run a repeatable process for two test matters and verify it produces consistent outputs and naming.
Export control with production-ready outputs
Why it matters
Export control with production-ready outputs matters because hosting often becomes the final gate for what opposing parties receive. If output controls are limited or inconsistent, your review-to-production handoff suffers.
How to check
Request a production-style export demo and show which fields and formats can be configured. Export the same sample evidence under two different settings and confirm differences are traceable and predictable in the output files.
Upload and export throughput behavior
Why it matters
Upload and export throughput behavior affects real case timing, especially when large evidence sets and repeated exports are common. Hosting that stalls during transfers can derail deadlines.
How to check
In the sandbox, measure time to upload a mixed folder and then time to complete an export job for that same dataset. Ask what limits or throttles exist, and whether jobs queue or fail when multiple exports run at once.
Red flags
- RBAC only works for the UI, not for exports and API actions
- Audit logs lack object-level detail or miss key events from admin changes
- Exports look configurable in demos but ignore your production settings
Fit by situation
- If you run multiple matters with shared staff, prioritize Provisioning and RBAC for case workspaces.
- If holds often change mid-case, prioritize Hold controls and evidence lifecycle actions.
- If your team must repeat exports on a schedule, prioritize Export control with production-ready outputs.
