06Sourced 2025-2026 signals
What's new at ProvePrivacy (2025-2026, sourced)
These sourced updates were researched on 2026-07-05 and are listed separately from the live comparison table so existing profile claims remain unchanged.
ProvePrivacy released a major platform redesign, "v8.0", on 4 July 2026. The most substantive change is that risk management is no longer a separate module: risks identified from a processing activity are now connected directly to the RoPA record that generated them, giving a single Article 30 view instead of a siloed risk register. The release also adds a new "Information Asset Module" with deep-dive functionality to identify data types held on individual assets, a tabbed RoPA navigation with breadcrumbs, and enhanced Data Subject Rights and FOI reporting.
ProvePrivacy's Controls Management now explicitly supports alignment to ISO 27701 and NIST CSF 2.0 in addition to ISO 27001 and the NCSC Cyber Assessment Framework (CAF) already noted in the existing profile — a broader control-framework set than previously documented.
ProvePrivacy holds a G2 rating of 4.5 out of 5, based on a small sample of only 4 published reviews as of mid-2026 — consistent with the existing profile's note of "few public reviews to date," now with a specific (though statistically thin) figure attached.
07Sourced 2025-2026 signals
What's new at OneTrust (2025-2026, sourced)
These sourced updates were researched on 2026-07-05 and are listed separately from the live comparison table so existing profile claims remain unchanged.
OneTrust appointed John Heyman as Chief Executive Officer effective February 9, 2026, succeeding founder Kabir Barday, who moves to a strategic advisory role on the Board of Directors; Doug Owens was also named CFO (announced April 28, 2026). This leadership transition is not reflected in the current profile, which does not mention company leadership at all.
As of late 2025/January 2026, multiple reports (not an official OneTrust announcement) indicate OneTrust is in active discussions with private-equity firms (reportedly including Vista Equity Partners, Thoma Bravo, Blackstone, KKR, and Silver Lake) about a potential sale valued north of USD 10 billion - more than double its last official valuation of USD 4.5 billion (2023). No deal has been officially confirmed by OneTrust in the sources found; this should be treated as reported/rumored market activity, not a confirmed fact.
Independent of the Capterra rating already cited (4.3/5, 55-56 reviews), OneTrust's products are also reviewed on G2: OneTrust Privacy Automation is rated 4.3/5 from roughly 152 reviews and OneTrust Tech Risk & Compliance is rated 4.6/5 from roughly 109 reviews, with recurring reviewer themes of a steep initial setup/configuration learning curve alongside praise for consolidating privacy workflows in one platform.
OneTrust was named a Visionary in Gartner's inaugural 2026 Magic Quadrant for AI Governance Platforms (the first-ever Gartner MQ for this specific market) and was also named a Leader in Gartner's first Magic Quadrant for Third-Party Risk Management Tools for Assurance Leaders (2026). Neither analyst recognition is currently referenced in the profile, which cites only Capterra for third-party validation.
OneTrust has launched new AI-governance capabilities in 2026 beyond what the existing profile lists under 'AI governance': a Privacy Breach Response Agent built with Microsoft Security Copilot (vendor-announced), plus a March 2026 platform expansion adding real-time AI agent detection/inventory across AWS Bedrock, Azure Foundry and Google Vertex, and continuous guardrail-violation monitoring for AI agents, models and data.
OneTrust disclosed a security incident (per its own blog; not independently verified by a regulator) in which unauthorized activity was identified in its Salesforce environment on June 17, 2026, tied to a broader third-party breach of the Klue-Salesforce integration that occurred June 11-12, 2026. OneTrust states its investigation indicates the exposure is isolated to third-party CRM-related data accessible through that integration, and it disabled the Klue Battlecards integration and engaged external forensic specialists. This is not referenced anywhere in the current profile.
08Overlap and gaps
ProvePrivacy vs OneTrust: 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; Breach/incident management; plus 6 more | If your requirement sits here, compare workflow depth, implementation effort, evidence quality and price. |
| Only ProvePrivacy publicly confirmed | Public pricing | Keep ProvePrivacy on the shortlist for these requirements, but ask OneTrust whether the same capability exists in current product scope. |
| Only OneTrust publicly confirmed | AI governance; Consent management; Cookie/tracker scanning; Multi-entity support; Spreadsheet import; PDF/CSV/Excel export | Keep OneTrust on the shortlist for these requirements, but ask ProvePrivacy 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. |

10Where each is stronger
ProvePrivacy vs OneTrust: the differences that matter
On the tracked capabilities, ProvePrivacy and OneTrust overlap on most rows; the differences that matter are the capabilities only one of them evidences, plus the depth and focus each brings to them.
- Only ProvePrivacy (not OneTrust) is evidenced for: Public pricing.
- Only OneTrust (not ProvePrivacy) is evidenced for: AI governance, Consent management, Cookie/tracker scanning, Multi-entity support, Spreadsheet import, PDF/CSV/Excel export.
- ProvePrivacy: Breach and incident management as a packaged module - it notifies the DPO, lets them stand up an investigation team and generates the supervisory-authority breach report.
- ProvePrivacy: A built-in training / e-learning component (Online Awareness, Data Champion Course, GDPR Foundation) delivered through the platform.
- OneTrust: Enterprise-suite breadth across privacy, consent, third-party risk, AI governance, GRC and regulatory-change management in one platform.
- OneTrust: Consent and preference management plus cookie and tracker scanning.
11Customer due diligence
Questions customers should ask before choosing ProvePrivacy or OneTrust
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 ProvePrivacy and OneTrust 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 ProvePrivacy and OneTrust 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 ProvePrivacy or OneTrust package.
12Shortlisting notes
Choosing between ProvePrivacy and OneTrust
Assess ProvePrivacy and OneTrust against the workflow you actually need to run - RoPA, DPIA, vendor and risk records - and how defensibly each exports its evidence.
- Shortlist ProvePrivacy when a fixed-cost, unlimited-user UK platform with Data Champions, breach handling and built-in training matches the programme you want to run.
- Shortlist OneTrust when enterprise-suite breadth, existing OneTrust investment, partner ecosystem or global programme scale is the primary requirement.
- Put the same case to ProvePrivacy and OneTrust: take one processing activity through its assessment, the RoPA update, supplier evidence, the privacy risk and a defensible export, and watch where each needs manual work.
13Ireland & UK
ProvePrivacy vs OneTrust: Article 30 records for Irish and UK teams
Both ProvePrivacy and OneTrust 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 ProvePrivacy or OneTrust 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 | ProvePrivacy | OneTrust | Why customers care |
|---|---|---|---|
| Controller record | Ask ProvePrivacy to show the Article 30(1) controller fields for one processing activity, including purposes, categories, recipients, transfers, retention and security measures. | Ask OneTrust 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 ProvePrivacy to show Article 30(2) processor records separately from controller records, scoped to the controller on whose behalf processing is carried out. | Ask OneTrust 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 ProvePrivacy how EU GDPR and UK GDPR records are separated or tagged for Irish and UK entities. | Ask OneTrust 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 ProvePrivacy for a complete export that a legal entity could provide without giving the regulator product access. | Ask OneTrust 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 ProvePrivacy and OneTrust 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 ProvePrivacy or OneTrust?
- Export - can ProvePrivacy or OneTrust let each legal entity produce a self-contained record its own supervisory authority can read?
