Use this checklist to get from "people are using AI tools somewhere" to "we know what is in use, what data goes into it, who can do what, and what we do when something goes wrong". It is ordered the way most organisations need to tackle it. You do not need to finish a section before starting the next, but do not skip the first two.
Tick items as you go. Print it, or download the Markdown version and put it in your own tracker.
Not legal advice. This is general good-practice guidance, not a compliance certificate and not advice for your specific circumstances. Check legal obligations with a qualified adviser.
1. Ownership and scope
Someone has to own this, or it will not happen.
2. Shadow AI discovery
You cannot protect what you do not know about. Start by finding out what is already in use.
3. Data classification and rules
4. Prompt and data-leak controls
5. Vendor due diligence
6. Access control
7. Logging and monitoring
8. Human oversight
9. Secure build and supply chain (if you build or integrate AI)
10. Incident response
11. Review and improve
A realistic first 30 days
- Week 1: name an owner, agree the scope, run the staff survey, and publish a short interim rule: "Do not put secrets, personal data or confidential information into AI tools that are not approved."
- Week 2: build the first tool inventory from the survey, identity logs and connected apps. Approve a small set of tools that fit the most common needs.
- Week 3: publish the acceptable-use policy, set data rules per tool, switch on single sign-on and multi-factor authentication, and remove unneeded connectors.
- Week 4: brief staff using real examples, add AI scenarios to your incident plan, and set up logging for anything that can take actions.
Optional, from Pyralink. Item 4 mentions controls that warn before sensitive data is pasted into AI tools. Pyralink's AI Paste Guard is a Chrome extension that does this: it checks what is pasted into AI chat prompt boxes and warns first, and the checks run on the device. This checklist works whether or not you use it.
