What's the difference between a confidentiality clause and an NDA?

An NDA is a standalone agreement focused entirely on protecting confidential information. A confidentiality clause is one section within a larger contract. The legal effect is similar — both create enforceable duties of secrecy. The practical difference: NDAs are used before sharing sensitive information (like during due diligence), while confidentiality clauses protect information exchanged during an ongoing business relationship.

How long does a confidentiality clause last?

Typically 2–5 years after the contract ends, though some last indefinitely for trade secrets. The duration should match the sensitivity of the information. Customer lists might need 2 years of protection; proprietary algorithms or formulas might need perpetual protection. If the clause doesn't specify a duration, courts will impose a 'reasonable' period — which is unpredictable.

What information is typically excluded from confidentiality clauses?

Standard exclusions: information that's publicly available, information the receiving party already knew, information received from a third party without restriction, and information independently developed without using confidential material. These exclusions are essential — without them, the clause could be challenged as overbroad and unenforceable.

Can a confidentiality clause survive after the contract ends?

Yes, and it should. Confidentiality clauses typically include a 'survival' provision that keeps the obligation active for a set period after termination. Without survival language, there's a risk the obligation dies when the contract ends — exactly when you're most vulnerable to information leaks (like a departing employee or vendor).

What happens if someone violates a confidentiality clause?

The injured party can sue for breach of contract. Remedies include monetary damages (lost profits, competitive harm), injunctive relief (court order to stop further disclosure), and in some cases, recovery of attorney's fees. Many contracts specify that a breach of confidentiality entitles the injured party to seek an injunction without posting a bond — because monetary damages alone can't undo the harm of disclosed secrets.

Confidentiality Clause

Requires parties to keep sensitive information secret — covering trade secrets, business plans, customer data, and proprietary methods.

What it means

A section within a larger contract that requires one or both parties to keep certain information secret. Unlike a standalone NDA, a confidentiality clause is embedded inside another agreement — a services contract, employment agreement, or partnership deal. It defines what counts as confidential, who can access it, and how long the obligation lasts.

How it works in practice

You hire a development agency to build your product. The services agreement includes a confidentiality clause covering your source code, business plans, user data, and pricing strategy. Six months later, you discover the agency shared your architecture diagrams with another client building a competing product. The confidentiality clause gives you grounds to terminate the contract and sue for damages — without it, you'd be arguing implied duty, which is much harder to prove. Confidentiality clauses are in virtually every business contract. The key differences between a strong and weak clause: specificity about what's confidential, clear exclusions (publicly available info, independently developed material), defined duration, and spelled-out remedies for breach.

Example clause language

Each Party agrees to hold in strict confidence all Confidential Information received from the other Party and shall not disclose such information to any third party without prior written consent. 'Confidential Information' means all non-public information disclosed by either Party, whether orally, in writing, or electronically, that is designated as confidential or that reasonably should be understood to be confidential. This obligation shall survive termination of this Agreement for a period of three (3) years.
