A client sends you a contract with a confidentiality clause. Another sends a separate NDA. Are they the same thing? Not exactly — and the differences matter more than most freelancers realize. Signing either without understanding the scope can limit what work you can discuss, show, or do in the future.

What is a confidentiality clause?

A confidentiality clause is a section inside a broader contract (like a freelance services agreement) that restricts you from sharing information you learn while working with the client. It's embedded — part of the same document as your payment terms, deliverables, and IP ownership.

“Contractor agrees to keep confidential all information disclosed by Client in connection with the services, including business plans, technical data, and customer information, and shall not disclose such information to any third party without prior written consent.”

What is an NDA?

A non-disclosure agreement (NDA) is a standalone contract focused entirely on confidentiality. It's signed before or alongside the main contract — often before a client will even share project details with you. NDAs tend to be more detailed and legally robust than embedded confidentiality clauses.

Mutual NDA

Both parties agree to keep each other's information confidential. Common when both sides are sharing sensitive details.

One-way NDA

Only one party (usually the freelancer) is restricted. The client can share your information freely. Watch for this imbalance.

Key differences at a glance

Factor	Confidentiality Clause	NDA
Format	Embedded in main contract	Standalone document
Detail level	Usually brief	More comprehensive
Timing	Signed with the main contract	Often signed before project starts
Enforceability	Enforceable but less specific	Typically more enforceable
Scope	May be vague	Usually defines confidential info precisely

Red flags in both

✗No expiration date — confidentiality obligations that last forever are unusual and often unenforceable
✗Overly broad definition of "confidential information" that could include public knowledge
✗One-way obligations — only you are restricted, the client is free to share what you tell them
✗No carve-outs for information you already knew or that becomes public through no fault of your own
✗Portfolio restrictions — clauses that prevent you from ever mentioning you worked with the client

How Clausix handles both

Whether confidentiality obligations are in a standalone NDA or buried in your main contract, Clausix identifies and flags them. It highlights missing expiration dates, one-sided obligations, and overly broad definitions — in plain English.

Quick checklist

☐Is confidentiality mutual — or only binding on you?
☐Is there an expiration date on the confidentiality obligation?
☐Are standard carve-outs included (public info, info you already knew)?
☐Does the agreement prevent you from listing the client in your portfolio?
☐Is "confidential information" narrowly defined — not just "everything we discuss"?
