What Is a Confidentiality Clause?
A confidentiality clause (or nondisclosure obligation) restricts one or both parties from sharing the other's private information — pricing, plans, code, customer lists — with anyone outside the deal. It can live inside a bigger contract or stand alone as an NDA.
Why it matters
Confidentiality itself is routine; nearly every serious business contract has it. The risk is in scope and duration. An obligation that covers "all information," binds only you, and never expires is a liability you carry long after the deal ends — one you can breach by accident in a future job or project.
What to watch for
- One-way obligations: you're bound; they aren't (common when the other side supplied the template).
- "All information" definitions with no exclusions.
- Perpetual duration — no end date on the obligation.
- Missing standard exclusions: information that's public, already known to you, or independently developed should never be "confidential."
- Confidentiality doing a non-compete's job: wording so broad it effectively bars you from working in the field (compare non-compete).
A realistic example
A consultant signs a client's template with perpetual confidentiality over "all business information." Two years later, a new client in the same industry asks for a standard market overview. Much of what the consultant knows is now arguably covered by the old clause — a cloud over ordinary work.
What to ask for
- Mutual obligations — both sides keep each other's information confidential.
- A defined term: 2–3 years is a common, reasonable duration for most business information.
- The standard exclusions (public, previously known, independently developed, legally compelled disclosure).
