OneTrust appointed John Heyman as chief executive officer effective February 9, 2026, succeeding founder Kabir Barday, who moved to a strategic advisory role on the board. Doug Owens was named chief financial officer in April 2026.
Late-2025 and January-2026 reporting described OneTrust as in discussions with private-equity firms about a potential sale valued above USD 10 billion. No transaction was officially confirmed, so this remains reported market activity rather than a confirmed deal.
G2 lists OneTrust Privacy Automation at 4.3/5 from roughly 152 reviews and OneTrust Tech Risk & Compliance at 4.6/5 from roughly 109 reviews. Review themes include a steep initial setup and configuration curve alongside praise for consolidating privacy workflows.
OneTrust was named a Visionary in Gartner's inaugural 2026 Magic Quadrant for AI Governance Platforms and a Leader in Gartner's first Magic Quadrant for Third-Party Risk Management Tools for Assurance Leaders.
OneTrust announced a Privacy Breach Response Agent built with Microsoft Security Copilot and a March 2026 expansion adding real-time AI-agent detection and inventory across AWS Bedrock, Azure Foundry and Google Vertex, plus guardrail-violation monitoring for AI agents, models and data.
OneTrust disclosed unauthorised activity in its Salesforce environment on June 17, 2026, linked to a broader Klue-Salesforce integration breach on June 11-12. OneTrust says exposure was limited to third-party CRM-related data accessible through that integration and that it disabled the Klue Battlecards integration and engaged forensic specialists.

What's new at DataGrail (2025-2026, sourced)
Sources reviewed on 2026-07-05. Confirm current features and commercial terms directly with the vendor.
DataGrail launched Vera on March 18, 2026. DataGrail describes Vera as an AI privacy agent that drafts PIAs, DPIAs, AI risk assessments and TIAs from live system metadata and prior assessments. The company says Vera uses a single-tenant architecture, six-stage prompt protection, no external data training, human review for every output and no action without user approval; it reports assessment completion 90% faster.
DataGrail was named a Leader in the IDC MarketScape: Worldwide Data Privacy Compliance Software 2025 Vendor Assessment, announced November 13, 2025, for the second consecutive year. IDC cited DSAR and consent automation, an extensive integration network, ease of use and customer success as strengths.
DataGrail's Risk Register, rolled out through 2025, uses the company's system-detection network across more than 2,500 integrations to surface and score risks including unapproved AI-model use, sensitive-data processing by AI-enabled systems and third-party vendor compliance gaps.
DataGrail Consent, launched in June 2024, won the 2025 SC Award for Best Compliance Solution. Coverage names Drata, Carvana, Sportsman's Warehouse and Skillshare as adopters.
G2's product review page showed 184 DataGrail reviews in mid-2026. DataGrail's number-one rating claim is vendor marketing and does not establish an independent G2 category ranking.
08Overlap and gaps
OneTrust vs DataGrail: 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 8 more | If your requirement sits here, compare workflow depth, implementation effort, evidence quality and price. |
| Only OneTrust publicly confirmed | Breach/incident management; Policy/notice management; Training module; Spreadsheet import | Keep OneTrust on the shortlist for these requirements, but ask DataGrail whether the same capability exists in current product scope. |
| Only DataGrail publicly confirmed | DataGrail has no unique tracked public capability against OneTrust in this dataset. | Keep DataGrail 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 DataGrail
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 DataGrail 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 DataGrail 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 DataGrail package.
12Shortlisting notes
Choosing between OneTrust and DataGrail
Weigh OneTrust and DataGrail on the workflow you must run end to end - RoPA, DPIA, vendor and risk records - and on how defensibly each one exports what it holds.
- Shortlist OneTrust when enterprise-suite breadth, existing OneTrust investment, partner ecosystem or global programme scale is the primary requirement.
- Shortlist DataGrail when automated DSRs, system detection, data discovery and integration-led privacy operations are the primary buying criteria.
- Ask OneTrust and DataGrail 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 DataGrail: Article 30 records for Irish and UK teams
Both OneTrust and DataGrail 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 DataGrail 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 | DataGrail | 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 DataGrail 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 DataGrail 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 DataGrail 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 DataGrail 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 DataGrail model controller and processor records separately, scoped by legal entity?
- EU and UK GDPR - can OneTrust or DataGrail hold both on one register, mapped to what the DPC and ICO expect?
- Export - does OneTrust or DataGrail let each legal entity produce a stand-alone record its supervisory authority can read without platform access?
