FTI Consulting
enterprise_vendorOffers investigations and forensic consulting services that include structured review of media artifacts, communications trails, and audit-ready evidence packages.
Audit-ready evidence lineage through a configurable data model and evidence traceability controls.
Media audit work often needs ingestion from ad servers, analytics exports, content archives, and partner feeds. FTI Consulting fits situations where these feeds require a shared schema, field-level normalization, and repeatable provisioning steps for new campaigns or channels. Governance controls are aligned to audit defensibility, with role-based access and documented approval flows for evidence used in reporting.
A tradeoff appears when requirements demand highly custom automation without clear integration points, since schema extensions and mapping rules still require design effort. FTI Consulting works best when a defined data model and evidence taxonomy can be agreed early, then iterated through a structured configuration cycle. Usage fits teams running frequent audits that must keep audit logs and evidence lineage intact under changing stakeholders.
- +Integration depth across heterogeneous media and analytics data sources
- +Configurable data model for evidence traceability and audit-ready schema
- +Governance controls with RBAC and auditable review workflows

How to Choose the Right Media Audit
Analysts separate media audit options by how they ingest and reconcile your delivery data, how strictly they explain mismatches, and how well they let you document findings for stakeholders. The biggest differentiators you’ll feel in demos are reporting audit trail, discrepancy rules, and exportable reconciliation reports.
Source data connectors and file import
Why it matters
Media audit depends on getting the same inputs each time, so Source data connectors and file import affects whether audits are repeatable. Gaps force manual patching and weaken your audit trail.
How to check
Ask for a demo that imports at least two common input types (one export file and one platform log/report). Then run the same audit on a sample dataset and check whether field names, IDs, and dates land consistently.
Discrepancy detection logic
Why it matters
Discrepancy detection logic determines whether the audit finds real gaps or just noise. For media audit, you need clear rules for what counts as a mismatch and how it’s categorized.
How to check
Request to see a configurable mismatch rule (for example, tolerance on rate or quantity fields). Then change the tolerance in the UI and verify the results update in a traceable way.
Reporting audit trail on findings
Why it matters
Reporting audit trail on findings matters because stakeholders need to trust why each issue exists. Without provenance links back to the input rows, audits turn into commentary.
How to check
Open a sample finding and confirm it shows the exact source rows/columns used to compute it. Export the audit view and check that the explanation stays attached outside the product.
Reconciliation report exports
Why it matters
Reconciliation report exports let analysts hand off work without rebuilding it in spreadsheets. In media audit, export structure is part of the evidence.
How to check
Generate an export that includes summary and row-level detail. Confirm you can select the date range and which fields appear, and verify the exported file matches what the UI shows.
Scheduling and repeatable audit runs
Why it matters
Scheduling and repeatable audit runs reduce drift between versions of an audit. For media audit, repeatability is what makes trend checks and re-audits credible.
How to check
Ask whether you can schedule an audit run with saved configuration, then re-run it on the same input and compare outputs. Check whether the system keeps prior run outputs for side-by-side review.
Workspace roles and permissions
Why it matters
Workspace roles and permissions control who can edit rules and who can only review results. For media audit, that governance prevents accidental changes to evidence.
How to check
In the demo, create two roles (viewer and editor) and attempt to modify discrepancy rules as each user. Verify that audit logs capture rule edits and that read-only users can’t change configuration.
Red flags
- Findings show totals but not the underlying source evidence rows
- Discrepancy rules can’t be adjusted or are undocumented
- Exports lose explanations or don’t match the on-screen results
Fit by situation
- If you routinely audit after each delivery cycle, prioritize scheduling and repeatable audit runs.
- If your inputs arrive as mixed exports and platform reports, prioritize Source data connectors and file import.
- If multiple teams need to review evidence, prioritize Reporting audit trail on findings.
