07Shortlisting notes
Choosing between ProvePrivacy and OneTrust
ProvePrivacy and OneTrust should each be assessed on the published fit above against the workflow you actually need to run - RoPA, DPIA, DSAR, vendor and risk records, and how defensibly each exports.
- Shortlist ProvePrivacy or OneTrust where its broader suite, integrations or specific modules match the programme you want to run.
- Ask each vendor to 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.
08Ireland & UK
ProvePrivacy vs OneTrust for RoPA in Ireland and the UK
Records of processing activities are required 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 must be documented under UK GDPR.
Whichever of ProvePrivacy or OneTrust you weigh, the questions for an Irish or UK team are the same: how deep is the Article 30 record, and how defensibly does it export?
- Article 30(1) and 30(2) - does it model controller and processor records separately, scoped by legal entity?
- DPC (Ireland) and ICO (UK) documentation - are EU and UK GDPR distinguished on one register?
- Export - can each legal entity produce a self-contained record its own supervisory authority can read?
