Using AI Tools at Work Without Leaking Your Business: A Practical Policy

Whether or not you’ve adopted AI officially, your staff already use it — drafting emails, summarising documents, debugging spreadsheets. That’s mostly good news for productivity. The risk isn’t the AI; it’s the paste. What goes into a tool leaves your control, and "shadow AI" use means it’s happening without any rules at all.

The actual risks, ranked honestly

• Data leakage: client records, financials or credentials pasted into consumer tools with unclear retention.
• Account risk: staff signing up to unvetted AI services with their work email and a reused password.
• Over-trust: AI output (a contract clause, a config change) applied without review — confident and wrong is the failure mode.
• Incoming AI: more convincing phishing and voice-clone fraud aimed at you (a separate battle — train for it).

A starter policy you can adopt this week

• Green: public info, general drafting, brainstorming — any approved tool.
• Amber: internal business content — only in business-tier AI accounts where data isn’t used for training.
• Red: client personal information, credentials, financial records, anything under NDA — never into external AI tools.
• Always: work accounts with MFA for AI services; human review before AI output touches customers, money or systems.

Make the safe path the easy path

Bans don’t work; they just push use underground. Pick one or two sanctioned tools with business data protections, pay the modest subscription, and tell the team clearly what’s green, amber and red. You get the productivity, they get clarity, and your client data stays where it belongs.
