What is the definition of A Non Disclosure Agreement (NDA)?

A non-disclosure agreement, or NDA, is a contract signed between parties which creates an agreement to keep any important information out of the public domain. This is most typically associated with new ideas, sensitive information or any other kind of business process. Employees usually have to sign NDA's upon joining a company as they are likely to be privy to important information which the company would not want to be leaked.

An NDA may also be known as a Confidentiality Agreement (CA).
