An NDA clause (non-disclosure agreement clause) is a contractual provision that creates a legally binding obligation to keep specified information confidential. It defines what counts as "confidential information," who must protect it, how it must be handled, and what happens if it's disclosed without authorization. NDA clauses appear both as standalone agreements and as embedded sections within larger contracts — freelance agreements, employment contracts, vendor MSAs, agency retainer agreements, and SaaS subscription terms. The clause protects the disclosing party (the person or entity sharing the information) by giving them legal recourse if the receiving party leaks, uses, or shares that information without permission.
of organizations use NDAs as a standard part of their vendor and contractor onboarding process.
An NDA clause restricts the receiving party from disclosing, using, or sharing information defined as "confidential" in the agreement. The scope depends entirely on how the contract defines that term — and this is where the most consequential variation occurs.
A standard NDA clause will define confidential information broadly. Here is example language from a typical freelance NDA:
"Confidential Information means any and all information or data that has or could have commercial value or other utility in the business in which Disclosing Party is engaged. If Confidential Information is in written form, the Disclosing Party shall label or stamp the materials with the word 'Confidential' or some similar warning. If Confidential Information is transmitted orally, the Disclosing Party shall promptly provide writing indicating that such oral communication constituted Confidential Information."
The key phrase here is "could have commercial value" — this is deliberately expansive. Courts have generally interpreted this to cover almost any business information that isn't already public knowledge.
A well-drafted NDA clause includes explicit carve-outs — categories of information that are excluded from confidentiality obligations even if they otherwise meet the definition. The standard carve-outs are:
If your NDA clause is missing these carve-outs, flag it. An NDA without standard carve-outs is overbroad and may create obligations that are difficult or impossible to comply with.
Duration is one of the most negotiated aspects of NDA clauses. The typical range for freelance and vendor NDAs is 2 to 5 years after the agreement ends or after the disclosure of the specific confidential information.
Many NDAs include a survival clause that extends confidentiality obligations for trade secrets indefinitely, even after the rest of the NDA expires:
"The obligations of confidentiality in this Agreement shall survive termination of this Agreement for a period of three (3) years; provided, however, that with respect to any Confidential Information that constitutes a trade secret under applicable law, the obligations shall survive indefinitely."
This structure is actually reasonable — finite duration for general confidential information, indefinite protection only for actual trade secrets (which have their own legal definition and require the disclosing party to take reasonable steps to keep them secret). The problematic version is an NDA with no time limit on all confidential information, not just trade secrets.
The standard duration range for freelance and vendor NDA clauses. An indefinite NDA covering all confidential information (not just trade secrets) is a red flag that courts have sometimes voided.
Both parties are bound equally. Neither party can disclose the other's confidential information. Appropriate when both parties are sharing sensitive information — for example, a collaboration between two businesses where each party is disclosing proprietary methods, pricing, or technology to the other.
Only one party — typically the receiving party, often the freelancer or contractor — is bound by confidentiality obligations. The disclosing party faces no restrictions. This structure is common and appropriate when only one party is sharing sensitive information. It becomes a red flag when both parties are sharing sensitive information and only one party is restricted.
NDA language appears as a clause or section within a freelance agreement, employment contract, or vendor MSA rather than as a standalone document. These are functionally equivalent to standalone NDAs — the same rules and red flags apply. Many freelancers fail to notice NDA clauses in larger contracts because they're buried in section 7 or 8 of a 30-page agreement.
Not all NDA clauses are created equal. These are the patterns that should prompt you to either negotiate or consult an attorney before signing:
NDA clauses are negotiable in most freelance and vendor contexts. Enterprise clients with legal departments may resist changes to their standard templates — but many will accept targeted, reasonable modifications. Here are the most effective asks:
"Confidential Information means all information about the Company's business, operations, technology, finances, customers, and any other information designated as confidential."
"Confidential Information means only information that is (a) marked as 'Confidential' at the time of disclosure, or (b) disclosed orally and identified as confidential in writing within 10 business days of disclosure, limited to the categories of: customer lists, proprietary software source code, and financial projections."
"Receiving Party's confidentiality obligations under this Agreement shall continue indefinitely."
"Receiving Party's confidentiality obligations under this Agreement shall continue for a period of two (2) years following the termination of the Agreement, except that obligations with respect to information that constitutes a trade secret under applicable law shall continue for as long as the information remains a trade secret."
If you are sharing proprietary information with the client — your processes, pricing models, client lists, or methodologies — request that the NDA be made mutual. The ask is simple: "I'll also be sharing confidential business information. Let's make this mutual."
Make sure the following language is present: "Nothing in this Agreement shall restrict the Receiving Party's use of information independently developed by the Receiving Party without use of or reference to the Disclosing Party's Confidential Information." This protects you if you happen to build something similar in the future using your own knowledge.
This is not legal advice. NDA enforceability varies significantly by jurisdiction. California, for example, has unusually strong protections against certain restrictive covenants. For a binding opinion on your specific NDA, consult a licensed attorney in your state.
An NDA clause (non-disclosure agreement clause) is a contractual provision that legally obligates one or both parties to keep specified information confidential. It defines what counts as confidential information, who must protect it, how it must be handled, and what happens if it's disclosed without authorization. NDA clauses appear both as standalone agreements and as sections within larger contracts like employment agreements, freelance contracts, and vendor MSAs.
Most NDA clauses last between 2 and 5 years after the agreement ends or after confidential information is disclosed. Some NDAs include a "survival" clause that extends confidentiality obligations indefinitely for trade secrets, even after the rest of the NDA expires. Courts have sometimes voided indefinite NDA clauses as unenforceable, but a well-drafted indefinite clause tied specifically to trade secret protection often holds up. An NDA with no time limit on all confidential information — not just trade secrets — is worth flagging before you sign.
Breaking an NDA clause exposes you to several legal consequences: injunctive relief (a court order requiring you to stop the disclosure immediately), monetary damages for actual losses the other party suffered, liquidated damages if the contract specifies a fixed penalty, and attorney fee recovery if the NDA includes a fee-shifting clause. In cases involving trade secrets, you may also face claims under the Defend Trade Secrets Act (DTSA), a federal statute that allows for exemplary damages of up to two times actual damages plus attorney fees in cases of willful misappropriation.
Yes. NDA clauses are negotiable in most freelance and vendor contexts. The most common successful negotiations involve narrowing the definition of "confidential information" to specific categories, adding explicit carve-outs for publicly available information and independent development, shortening the duration to 2–3 years, and adding a mutual obligation so both parties are bound equally. Large enterprise clients may resist changes to their standard NDAs, but freelancers and small businesses successfully negotiate NDA terms regularly — especially when the asks are specific, reasonable, and accompanied by proposed replacement language.
A mutual NDA (also called bilateral) binds both parties equally — neither party can disclose the other's confidential information. A one-sided NDA (unilateral) only binds one party, typically the party receiving information. In freelance and vendor relationships, clients often present one-sided NDAs that only restrict the freelancer or contractor. Whether that's appropriate depends on context: if only one party is sharing sensitive information, a one-sided NDA makes sense. If both parties are sharing proprietary information — you're sharing your pricing models, client lists, or process documentation — a mutual NDA is more appropriate and worth requesting.
