One Paste at a Time
The biggest AI risk for most professionals is not robots taking their job — it's accidentally pasting a client's roadmap into a consumer AI tool and triggering a breach notification. These incidents are almost always preventable with one layer of awareness.
- Customer PII — names, emails, addresses, SSNs
- Employee PII and medical information
- Unreleased financials or M&A details
- Source code from a private repo
- Signed contracts or legal strategy
- Security credentials or API keys
- Internal memos — redact names and numbers first
- Meeting transcripts — strip names, use roles ("VP of Sales")
- Client names you could say publicly, in generic contexts
- Your own performance review — if you're comfortable with the provider

Three questions, three seconds. This mental check prevents 95 percent of AI confidentiality breaches.
A 3-second check before pasting anything to AI:
1. If this pasted into a public tweet right now,
would I lose my job or a customer?
2. Can I redact names, numbers, or dates without
losing the point?
3. Does my company's AI policy cover this use?
If any answer is unclear: don't paste. Use the enterprise
tool, or use a redacted version.Key terms in this lesson
The big idea: AI at work is a privilege that lives or dies on one skill — knowing what not to paste. A 3-second check saves careers, contracts, and reputations. Build the habit and you'll keep your AI access for life.
