Non-Disclosure Agreement (NDA)
Overview
An NDA is a legal agreement that restricts one or more parties from disclosing confidential information to unauthorized third parties.
It matters because it creates a formal confidentiality obligation around business, technical, financial, or operational information shared during a relationship or negotiation.
What An NDA Covers
An NDA usually defines:
- what counts as confidential information
- how that information may be used
- who is allowed to access it
- how long confidentiality obligations last
- which disclosures are excluded
- what happens if the agreement is breached
That makes it a practical control for information sharing before or during a project, partnership, hiring process, audit, or acquisition discussion.
Common Use Cases
NDAs are commonly used for:
- client and vendor onboarding
- agency and consulting engagements
- sharing product roadmaps or prototypes
- technical due diligence
- partnership and acquisition discussions
- hiring or contractor conversations involving sensitive material
They are especially useful when important information must be shared before a broader contract or SOW is finalized.
Mutual vs Unilateral NDA
NDAs are often either unilateral or mutual.
- A unilateral NDA mainly protects information disclosed by one party.
- A mutual NDA assumes both parties may disclose confidential information that needs protection.
That distinction matters because the expected direction of information flow affects risk and negotiation.
NDA vs MSA
An NDA is not the same as an MSA.
- An NDA focuses on confidentiality.
- An MSA defines the broader commercial and legal framework for an ongoing relationship.
In many service relationships, both documents may exist together.
Practical Considerations
- An NDA does not stop someone from disclosing information by itself; it creates contractual consequences and enforceable obligations.
- Confidential information should still be shared carefully and access should still be limited operationally.
- Definitions that are too broad or too vague can create friction or weaken enforceability.
- Duration, exclusions, and permitted-use language matter as much as the confidentiality clause itself.
Frequently Asked Questions
Is an NDA always required before starting work?
No. It depends on the sensitivity of the information being shared and the broader contract structure.
Does an NDA protect information forever?
Not necessarily. Most NDAs define a confidentiality period or survival term.
Is an NDA the same as an MSA?
No. An NDA is narrower and focuses on confidentiality, while an MSA governs the broader relationship.
