06Sourced 2025-2026 signals
What's new at GDPR Register (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.
GDPR Register's official pricing page (fetched July 2026) now lists the Pro tier at EUR 475/month billed annually (EUR 545/month billed monthly) — up from the EUR 425/EUR 490 figures currently cited on the Acompli comparison page. The Essential tier is unchanged at EUR 350/month annual (EUR 410/month monthly), and Governance remains custom/contact-sales.
The Pro tier now explicitly bundles 'Automatic Vendor Discovery' and an 'Ask AI Assistant' feature alongside LIA, DPIA and Risk Management — capability names not currently reflected in the comparison page's description of GDPR Register's feature set.
GDPR Register's own pricing page lists a 'Data Privacy Audit' feature as 'launching in 2026' on the Governance tier. This is a vendor roadmap claim, not a confirmed shipped feature, and should be treated as forward-looking rather than current capability.
GDPR Register's Security page states its primary hosting is AWS EU-Central (Frankfurt, Germany), with disaster-recovery backup in AWS Ireland and an offsite encrypted backup at a Zone Media data center in Tallinn, Estonia — a specific EU data-residency detail (including an Ireland-region backup) not currently included in the comparison page's security/jurisdiction discussion.
GDPR Register's About page states the company was founded in 2017 by legal professionals from Hedman Law Firm and is headquartered in Tallinn, Estonia; it credits CEO Krete Paal with prior experience as a DPO for the Estonian Police and Border Guard Board and later at Veriff. This is the vendor's own self-reported 'built by privacy practitioners' framing, not independently verified, but is a positioning detail not currently reflected on the comparison page.
Independent of the Capterra data already cited (5.0/5 from 3 reviews), G2 separately lists GDPR Register at 5.0/5 stars but based on only 1 review as of this search — a thin, distinct review base worth citing alongside Capterra rather than instead of it if the review-signal section is expanded.
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
GDPR Register 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; AI governance; plus 8 more | If your requirement sits here, compare workflow depth, implementation effort, evidence quality and price. |
| Only GDPR Register publicly confirmed | Public pricing | Keep GDPR Register on the shortlist for these requirements, but ask OneTrust whether the same capability exists in current product scope. |
| Only OneTrust publicly confirmed | Consent management; Cookie/tracker scanning; Policy/notice management; Training module | Keep OneTrust on the shortlist for these requirements, but ask GDPR Register 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 GDPR Register 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 GDPR Register 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 GDPR Register 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 GDPR Register or OneTrust package.
12Shortlisting notes
Choosing between GDPR Register and OneTrust
Assess GDPR Register and OneTrust against the workflow you actually need to run - RoPA, DPIA, vendor and risk records - and how defensibly each exports its evidence.
- Shortlist GDPR Register when its structured GDPR compliance feature set, breach handling and transparent public pricing match the team's operating needs.
- Shortlist OneTrust when enterprise-suite breadth, existing OneTrust investment, partner ecosystem or global programme scale is the primary requirement.
- Ask GDPR Register and OneTrust 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
GDPR Register vs OneTrust: Article 30 records for Irish and UK teams
Both GDPR Register 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 GDPR Register 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 | GDPR Register | OneTrust | Why customers care |
|---|---|---|---|
| Controller record | Ask GDPR Register 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 GDPR Register 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 GDPR Register 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 GDPR Register 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 GDPR Register 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 GDPR Register or OneTrust?
- Export - can GDPR Register or OneTrust let each legal entity produce a self-contained record its own supervisory authority can read?
