For a firm holding client financials and personal data, the AI conversation starts and ends with confidentiality. The upside is real, but it only counts if you can put the tool in front of a client and a regulator without flinching. The good news: the controls you need are well understood, and they should decide the platform — not the other way around.
What to confirm before any file goes in
- Training. Is your data excluded from model training by default — and is that contractual, not just a toggle?
- Retention & deletion. Are prompts and outputs stored, for how long, and can you require Zero Data Retention? See Zero Data Retention, explained.
- Data processing agreement. Is there a DPA covering sub-processors, breach notification, and your obligations to your own clients?
- Residency. Where is data processed and stored — and does that satisfy your jurisdiction’s data-protection rules?
- Firm controls. Admin dashboard, permission levels, immediate user removal, and knowledge that stays with the firm when staff leave.
The most common breach is not technical. It is a staff member pasting a sensitive file into a personal AI account. A governed platform plus a clear usage policy closes that gap faster than any feature.
Requirements first, then seats
Weight the decision toward what protects the firm. A practical split: data handling and governance ~30%, workflow fit ~25%, user and firm controls ~20%, document handling ~15%, adoption and integration ~10%. Features matter, but they matter less than a platform you can defend to a client and a reviewer.
Keep a human in the loop
AI should assist with preparation and review — not replace professional judgment, partner review, or the firm’s conclusion. A usage policy that says clearly what staff may upload and when partner review is required is as important as the platform itself.
This is the data-handling review at the center of a Celadon AI Audit. See how it maps to firms on our Accounting & Professional Services page, or read AI for professional-services firms.
Adopt AI you can defend
Celadon runs a full data-handling and governance review as part of every AI Audit — so you choose a platform you can put in front of a client and a reviewer.
