Need to write something faster? Summarize a document? Clean up an email?
AI tools make your job easier. With the help of artificial intelligence, you can get these tasks done in less than five minutes.
Unfortunately, there’s a side of AI that most employees aren’t being warned about: Using AI the wrong way can accidentally break company rules—and even legal agreements.
What’s Actually Happening When You Use AI?
When you paste information into an AI tool, you’re not just “using a tool.” Remember, somebody built and maintains these platforms. Therefore, you may be sharing that information with unauthorized third parties outside your company.
That includes…
Internal documents
Client details
Contracts
Financial information
Even if it feels harmless, once you enter that private data, it’s no longer secure and confidential.
You Could Be Violating an NDA (Without Even Knowing It)
Many companies—and their employees—are bound by Non-Disclosure Agreements (NDAs).
That means certain information must stay strictly confidential.
If you:
Paste internal data into AI
Upload documents for summarization
Ask AI to review company materials
You could be sharing confidential information with the AI provider, a third-party who should not have access to that data. Even if it was an honest mistake, that still counts as a privacy violation!
Compliance Rules Still Apply to You
You might not think about compliance in your day-to-day work, but these rules still apply to you!
If your company handles information such as customer data, payment information, health records, or other personally identifiable information (PII), you must follow strict rules governing that data. If you work with clients, vendors, or partners, their information is protected under these laws, too.
Putting that kind of information into AI tools, especially unapproved ones, can break those rules instantly. That can lead to fines and investigations that you don’t want to deal with.
Why Does Confidential Data Get Exposed Through AI?
Most people aren’t trying to do anything wrong.
They’re just:
Trying to work faster
Trying to be efficient
Trying to get help from AI
Even if you only want to save time, you may be exposing information that was never meant to leave your company. That’s what makes these behaviors so risky: It feels normal, but it isn’t always safe.
How to Use AI Securely at Work
You don’t need to stop using AI, but you do need to use it smarter.
Some best practices to follow:
Don’t paste sensitive information. If it’s confidential, client-related, or internal, then leave it out.
Keep prompts general. Instead of real data, use placeholders or summaries.
Use approved tools only. If your company provides an AI tool, use that instead of random ones online.
When in doubt, don’t paste it. It’s better to take an extra minute than to create a bigger problem.
AI is a powerful helper, but it doesn’t replace your responsibility to protect information. A few seconds of caution can save you and your company from serious legal trouble!
The bottom line: If you wouldn’t email it to a stranger, then don’t put it into AI.
