NDA vs. Confidentiality Agreement: Is There a Difference?
No real difference. “Non-disclosure agreement” and “confidentiality agreement” are two names for the same kind of contract, and neither name comes with a fixed set of terms. What matters is what the document says: who is bound, what’s covered, for how long, and whether it slips in anything beyond confidentiality.
One contract, many names
You’ll meet the same agreement under several names. They all do the same basic job: one or both parties promise to keep certain information confidential and to use it only for a stated purpose.
- Non-disclosure agreement (NDA): the most common name in general business.
- Confidentiality agreement (CA): common in mergers and acquisitions and in commercial real estate.
- Confidential disclosure agreement (CDA): often used by universities, research institutions and life sciences companies.
- Proprietary information agreement or secrecy agreement: older or industry-specific names for the same idea.
- Mutual NDA or unilateral NDA: names that tell you which way the obligations run. Mutual vs. one-way NDAs explains the difference.
Read the clauses, not the title
Some people use one name for one kind of deal and the other name for another, but no legal rule ties a title to particular terms. A document called a confidentiality agreement can be one-way or mutual, short or long, balanced or one-sided. In a dispute, what counts is what the parties agreed to, not the heading.
So review it the same way whatever it’s called: the definition of confidential information and its exclusions, the purpose, the term, who the information can be shared with, how it’s returned, and any extra clauses like non-solicitation. What to include in an NDA has a clause-by-clause checklist.
A standalone agreement vs. a confidentiality clause
The distinction worth knowing is between a standalone NDA and a confidentiality clause inside a bigger contract. Employment agreements, consulting and services agreements, partnership agreements and purchase agreements often include their own confidentiality section.
A standalone NDA is most useful before that bigger contract exists: while you’re scoping a project, collecting quotes, interviewing a candidate or exploring a deal. Once you sign the main contract, its confidentiality section usually governs the relationship from then on.
When a later contract replaces the NDA
Many contracts include an “entire agreement” clause saying the contract replaces all earlier agreements on its subject. If your services agreement or purchase agreement has one, it may replace your NDA, including its protection for what you shared during early talks, depending on how both documents are worded.
When you sign the main contract, check how it treats the NDA. Common approaches are to say the NDA stays in effect for information shared before signing, or to carry its protections into the new contract’s confidentiality section. For a significant deal, ask your lawyer to check this point specifically.
Related agreements that aren’t NDAs
Some agreements travel with NDAs but do different jobs:
- Non-compete: a promise not to compete. See NDA vs. non-compete.
- Non-solicitation: a promise not to recruit the other side’s employees or pursue its customers.
- Non-circumvention: a promise not to go around the party who introduced a deal, often asked for by brokers and other intermediaries.
- Invention or IP assignment: an agreement about who owns what someone creates. An NDA doesn’t transfer ownership of anything.
