NDA definition of confidential information clause
The definition of confidential information clause says what the NDA treats as confidential and what it does not. It should set clear boundaries that people can follow in day-to-day work.
If the definition is missing, vague, or too broad, it becomes hard to know what must be kept private. This page explains what to look for and what to ask for.
Quick answer
A definition of confidential information clause tells you what the NDA covers. In a strong NDA, the definition is clear, practical, and limited to real non-public information.
If the definition is missing, unclear, or too broad, small teams can end up guessing about what is protected and what is not.
Common red flags include:
- "Confidential Information" is never defined
- the definition is so broad that it could cover almost anything
- the NDA does not clearly limit confidential information to non-public information
- the NDA does not clearly say the information must actually be private and tied to the business
- the NDA does not say how information should be identified when it is not obvious
- spoken information is treated as confidential with no practical way to confirm what was shared

Glossary (quick definitions)
Definition:
This clause explains what counts as confidential information under the NDA.
Why it matters:
- It sets the boundaries for what must be kept private.
- It helps both sides follow the NDA in real work without guessing.
- If the definition is too broad, it can treat almost everything as confidential.
- If it is vague or missing, it can be harder to prove what was supposed to be protected.
Common red flags:
- The NDA never explains what "Confidential Information" means.
- The definition is a catch-all that could cover almost anything.
- The NDA does not clearly limit confidential information to information that is not public.
- The NDA does not give a practical rule for how to identify information as confidential when it is not obvious.
- The NDA treats anything said in a meeting as confidential with no clear way to confirm what was shared.
What a reasonable clause looks like:
- It clearly defines what counts as confidential information.
- It covers real non-public business, technical, or financial information.
- It makes clear that public information is not confidential.
- It excludes information the other side already knew before it was shared.
- It uses a simple rule for labeling information that is not obviously confidential.
What to look for
Below are common problems people miss and what to look for.
| Red flag | Why it's risky | What to ask for |
|---|---|---|
| The NDA uses the term "Confidential Information," but never clearly says what that means. | It is hard to know what must be kept private, which creates confusion later. | Add a clear definition of what counts as confidential information and say it can be shared in spoken, written, or digital form. |
| The definition is so broad that it could cover almost anything about the business. | A catch-all definition is hard to follow in real life and easy to break by accident. | Remove vague "anything about the business" wording and limit the definition to real non-public information. |
| The NDA does not clearly say that public information is not confidential. | Normal public facts can get treated like secrets just because they were mentioned in a meeting or email. | Add a clear rule that public information is not confidential, as long as it did not become public because of a breach. |
| The NDA does not clearly say how information should be identified as confidential when it is not obvious. | Small teams cannot follow the rule consistently if they do not know what has to be labeled. | Add a simple rule that information that is not obviously confidential should be labeled as confidential. |
| Spoken information is treated as confidential with no clear way to confirm what was shared. | People may disagree later about what was actually disclosed. | Say that spoken disclosures should be confirmed in writing within a reasonable time if they are not obviously confidential. |
Why not use ChatGPT or an AI contract assistant?
Chatbots and lighter-weight AI tools can help you review a contract faster, but they usually stop short of giving you a negotiation-ready output. For founders and business operators, the hardest part often comes after the review step: turning suggested changes into a real redline, explaining those edits clearly, and sending them back with confidence. Vesk is designed to take you further through that workflow for supported contract types.
Chatbots and AI contract assistants
- Better if you want a flexible, lower-cost starting point
- More sensitive to prompt wording and less consistent across repeated runs
- Often produce suggestions or summaries rather than a sendable package
- You still have to redline the Word document and defend the changes yourself
Vesk
- Better if you want an end-to-end NDA review, redlining, and negotiation workflow
- Designed for more consistent NDA review across repeated runs
- Benchmarks against industry-standard model agreements to help catch what matters
- Delivers a secure redline package with Word files, a negotiation brief, and a deal room
Calibrated against industry-standard agreements including Common Paper and Bonterms. Not endorsed by or affiliated with either.
What’s included in a secure redline package
Reviewing a contract is only part of the job. You still need a clear, professional way to send changes back and explain them, especially when the other side has procurement or in-house counsel. That is often the most stressful part for founders and business operators without legal training. A secure redline package is designed to make that step more organized, more defensible, and easier to handle with confidence. A secure redline package includes:
A negotiation brief that explains and supports the requested edits
A downloadable redlined Word .DOCX file with Track Changes on
A downloadable clean Word .DOCX file with the requested edits accepted
A secure deal room link you can review yourself or share with the counterparty
