Detailed Comparison

DORA RoI (fromCISO)

Free browser-based tool built by a practicing vCISO. Runs four validation layers — technical, DPM, DORA business rules, and 91+ EBA-specific checks — entirely in the browser. Supports Excel import, guided template filling, and xBRL-CSV export. No account required beyond a work email. All register data stays in the browser and is never transmitted to any server.

Best for: Lean compliance teams that need pre-submission validation without data upload or enterprise rollout.

Arendt DORA Validator (doravalidator.com)

Free tool by Arendt, a Luxembourg professional services firm. Validates uploaded xBRL-CSV ZIP packages against EBA rules. Does not support Excel import or template filling — designed for organizations that already have a complete xBRL-CSV package.

Best for: Teams that have already generated their xBRL-CSV package and need a second-opinion validation check.

Formalize ROI Validator

Free validator by Formalize. Accepts xBRL-CSV ZIP uploads and runs 117 validation checks server-side (data deleted after processing). Also available through Thomas Murray's enterprise RoI solution.

Best for: Organizations comfortable with server-side processing who need ZIP-level validation.

doraregister.io

Commercial SaaS platform with team collaboration features. Covers the full register lifecycle — data collection, validation, and export. Requires paid subscription and cloud storage of register data.

Best for: Larger organizations that want a team-based workflow with persistent cloud storage.

Excel Only

Many teams still prepare the register in Excel using EBA's template workbooks. While Excel handles data entry, it cannot validate cross-template foreign key references, check taxonomy codes, or generate the xBRL-CSV submission package.

Risk: In the 2024 ESAs dry-run exercise, only 6.5% of registers passed all 116 EBA data quality checks. Most failures came from cross-template reference errors that are invisible in Excel.

Consulting

External consultants or advisory firms review the register manually and prepare the submission package. Typical cost is €10,000–50,000 per submission cycle. Effective but expensive and slow — no guarantee of passing all 116 automated checks.

Best for: Organizations that need hands-on compliance advisory beyond just validation.

How to Choose

The right approach depends on where you are in the process:

• Already have xBRL-CSV? → Run it through DORA RoI or Arendt for a validation check
• Working in Excel? → Import into DORA RoI, validate, and export xBRL-CSV
• Need team collaboration? → Consider doraregister.io or an enterprise GRC platform
• Need full compliance advisory? → Engage a consulting firm, but still validate the final package yourself
• Want maximum data privacy? → DORA RoI processes everything in-browser with zero data transmission
