08Overlap and gaps
OneTrust vs TrustArc: what the public data actually shows
Feature count is only a starting point. A customer should separate shared coverage from unique public signals, then test whether the vendor can run the required workflow end to end.
| Decision point | Public signal | Buyer interpretation |
|---|---|---|
| Shared evidenced coverage | DPIA/PIA assessments; RoPA / Article 30; DSAR / privacy rights; Data mapping; Vendor risk; Privacy risk; AI governance; plus 11 more | If your requirement sits here, compare workflow depth, implementation effort, evidence quality and price. |
| Only OneTrust publicly confirmed | Training module | Keep OneTrust on the shortlist for these requirements, but ask TrustArc whether the same capability exists in current product scope. |
| Only TrustArc publicly confirmed | TrustArc has no unique tracked public capability against OneTrust in this dataset. | Keep TrustArc on the shortlist for these requirements, but ask OneTrust whether the same capability exists in current product scope. |
| Acompli reference column | No Acompli-only edge against both vendors appears in the tracked rows. | Use this as a third reference point where a narrower evidence-first privacy workflow may be preferable to a broader platform. |

11Customer due diligence
Questions customers should ask before choosing OneTrust or TrustArc
A useful comparison should move beyond a product page checklist. Customers should ask each supplier to prove the same live workflow, with the same assumptions, so the difference between platform breadth and usable evidence becomes visible.
Run one real workflow
Ask OneTrust and TrustArc to process the same example: new activity, assessment, RoPA update, supplier evidence, risk record, review and export.
Check evidence provenance
Confirm whether each important field in OneTrust and TrustArc has a source, owner, review date and change history, not just a completed form.
Validate exports
Ask both vendors for a regulator-readable export for one legal entity, including controller and processor records where relevant.
Confirm commercial scope
Verify which modules, integrations, service hours, data residency options and support commitments are included in the quoted OneTrust or TrustArc package.
12Shortlisting notes
Choosing between OneTrust and TrustArc
Assess OneTrust and TrustArc against the workflow you actually need to run - RoPA, DPIA, vendor and risk records - and how defensibly each exports its evidence.
- Shortlist OneTrust when enterprise-suite breadth, existing OneTrust investment, partner ecosystem or global programme scale is the primary requirement.
- Shortlist TrustArc when broad privacy-management coverage, consent governance, consulting support or established enterprise privacy operations are the main requirement.
- Ask OneTrust and TrustArc to each demonstrate the same workflow end to end: a new processing activity, its assessment, the RoPA update, supplier evidence, the privacy risk and an exportable audit trail.
13Ireland & UK
OneTrust vs TrustArc: Article 30 records for Irish and UK teams
Both OneTrust and TrustArc are weighed by Irish and UK privacy teams against the same fixed obligation: a record of processing activities under GDPR Article 30 - a controller record under Article 30(1) and a separate processor record under Article 30(2). In Ireland the Data Protection Commission (DPC) publishes Article 30 guidance; in the UK the ICO sets out what UK GDPR requires.
Whichever of OneTrust or TrustArc an Irish or UK team weighs, the questions are the same: how deep is the Article 30 record, is EU and UK GDPR distinguished on one register, and can each legal entity produce a self-contained export its own supervisory authority can read?
| Article 30 check | OneTrust | TrustArc | Why customers care |
|---|---|---|---|
| Controller record | Ask OneTrust to show the Article 30(1) controller fields for one processing activity, including purposes, categories, recipients, transfers, retention and security measures. | Ask TrustArc to show the Article 30(1) controller fields for one processing activity, including purposes, categories, recipients, transfers, retention and security measures. | A controller record must stand on its own when a regulator or auditor asks for it. |
| Processor record | Ask OneTrust to show Article 30(2) processor records separately from controller records, scoped to the controller on whose behalf processing is carried out. | Ask TrustArc to show Article 30(2) processor records separately from controller records, scoped to the controller on whose behalf processing is carried out. | Many tools capture controller records more clearly than processor records; customers should verify both. |
| Ireland and UK fit | Ask OneTrust how EU GDPR and UK GDPR records are separated or tagged for Irish and UK entities. | Ask TrustArc how EU GDPR and UK GDPR records are separated or tagged for Irish and UK entities. | Irish DPC and UK ICO expectations are close, but entity scope, local law references and export format still matter. |
| Standalone export | Ask OneTrust for a complete export that a legal entity could provide without giving the regulator product access. | Ask TrustArc for a complete export that a legal entity could provide without giving the regulator product access. | A defensible record should be readable outside the platform, with enough context to explain the processing activity. |
- Article 30(1) and 30(2) - does each of OneTrust and TrustArc model controller and processor records separately, scoped by legal entity?
- DPC (Ireland) and ICO (UK) - is EU and UK GDPR distinguished on one register for OneTrust or TrustArc?
- Export - can OneTrust or TrustArc let each legal entity produce a self-contained record its own supervisory authority can read?
