01Short answer
Responsum vs OneTrust
Responsum is positioned as: EU privacy management, risk, security, AI governance, third-party risk, awareness, training and compliance automation. OneTrust is positioned as: Enterprise privacy, trust, consent, third-party risk, AI governance and GRC suite. Across the tracked capabilities Responsum and OneTrust cover much of the same ground, so the decision rests more on operating model, depth and jurisdiction fit than on feature presence.
Responsum has broader public-documentation coverage in this comparison (20 of 20 tracked rows, compared with 19 for OneTrust). Capability coverage below reflects what each vendor publicly documents; Acompli is shown as a third reference column.

06Sourced 2025-2026 signals
What's new at Responsum (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.
Responsum now markets a 'Responsible AI Companion' — an AI feature that drafts structured records (vendors, assessments, processing activities) from text prompts, surfaces gaps/inconsistencies, and requires human review before anything is saved. This is a vendor marketing claim (not independently verified) but it narrows the AI-plus-human-approval framing Acompli currently uses as a point of differentiation, since Responsum now advertises the same human-in-the-loop AI-drafting pattern.
Responsum has an active G2 profile (not currently cited in the file, which only references Capterra) displaying self-reported G2 Fall 2024 badges — 'Easiest to Do Business With', 'Best Support', and 'High Performer' (Global, Europe, and EMEA) — per image/alt-text on Responsum's own homepage footer; G2's own review page (not independently confirmed for exact star rating via this research) also carries reviewer quotes praising ease of use, DPIA-to-processing-activity linking, and modular add-ons like phishing simulations/e-learning.
Responsum's own homepage footer displays an ISO/IEC 27001:2022 certification logo (image file referencing a Belgian accreditation body, 'RvA'), indicating Responsum holds ISO 27001 certification as an organization for its own operations — distinct from the already-documented fact that Responsum's Full GRC tier offers ISO 27001 as a customer-facing compliance framework module.
Responsum acquired the GDPR compliance division of RealCGR, a Belgian business-continuity-planning firm, effective March 1, 2024, bringing over RealCGR's privacy team and customers per Responsum's own announcement (CEO Alex Van Cauwenbergh quoted). This is not reflected anywhere in the current file.
Responsum's own 'framework compliance platform' page lists a materially broader regulatory roster than currently documented: beyond GDPR/UK GDPR/ISO 27001/NIST/NIS2/DORA/EU AI Act (already covered), it also names the UK DUA Act 2026, PDPA, PDPL, CCPA, CPRA, PIPEDA (Canada), LGPD (Brazil), POPIA (South Africa), HIPAA, GLBA, PIPL (China), COPPA, and custom frameworks — positioning Responsum as a multi-jurisdiction global compliance platform rather than an EU/GDPR-centric tool.
Responsum's own 'Responsum vs Competitors' page names a different rival set than Acompli's current FAQ: it directly compares itself against OneTrust, TrustArc and DPOrganizer, and lists BigID, Caralegal, Dastra, Keepabl, PrivacyEngine, Securiti, Wired Relations and WireWheel as alternatives. Several EU-native niche players named here (DPOrganizer, Caralegal, Dastra, Keepabl, Wired Relations) are absent from Acompli's existing FAQ answer on Responsum's competitors.
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
Responsum 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 12 more | If your requirement sits here, compare workflow depth, implementation effort, evidence quality and price. |
| Only Responsum publicly confirmed | Public pricing | Keep Responsum on the shortlist for these requirements, but ask OneTrust whether the same capability exists in current product scope. |
| Only OneTrust publicly confirmed | OneTrust has no unique tracked public capability against Responsum in this dataset. | Keep OneTrust on the shortlist for these requirements, but ask Responsum 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 Responsum 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 Responsum 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 Responsum 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 Responsum or OneTrust package.
12Shortlisting notes
Choosing between Responsum and OneTrust
Assess Responsum and OneTrust against the workflow you actually need to run - RoPA, DPIA, vendor and risk records - and how defensibly each exports its evidence.
- Shortlist Responsum when broad EU compliance operations, customization, awareness/training and connected privacy-risk-security workflows are central.
- Shortlist OneTrust when enterprise-suite breadth, existing OneTrust investment, partner ecosystem or global programme scale is the primary requirement.
- Ask Responsum and OneTrust to run one real scenario end to end - a new processing activity, its assessment, the RoPA update, supplier evidence, the privacy risk and an exportable audit trail - rather than a feature-by-feature demo.
13Ireland & UK
Responsum vs OneTrust: Article 30 records for Irish and UK teams
Both Responsum 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 Responsum 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 | Responsum | OneTrust | Why customers care |
|---|---|---|---|
| Controller record | Ask Responsum 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 Responsum 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 Responsum 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 Responsum 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 Responsum 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 Responsum or OneTrust?
- Export - can Responsum or OneTrust let each legal entity produce a self-contained record its own supervisory authority can read?
