NDA vs Confidentiality Agreement: Is There a Difference?

People use 'NDA' and 'confidentiality agreement' as if they mean different things. In practice, they're the same tool — but the details of how you use it matter.

The short answer

A non-disclosure agreement (NDA) and a confidentiality agreement are the same kind of document: a contract requiring one or both parties to keep certain information secret. The different names are just convention — there is no legal distinction between them.

What actually varies

One-way vs mutual

A one-way (unilateral) agreement protects information flowing in one direction — useful when only you are sharing something sensitive. A mutual agreement protects both parties, common when two businesses explore working together.

Context and tone

'Confidentiality agreement' often appears in employment and corporate settings, while 'NDA' is common in startup, investment and commercial contexts. The substance is the same.

What a good agreement needs

• A clear definition of confidential information
• A specific, lawful purpose for sharing it
• Sensible carve-outs for public or already-known information
• A reasonable time limit
• Clarity on what happens when the relationship ends
