A Non-Disclosure Agreement (NDA) is a legal contract between two or more parties that outlines confidential material, knowledge, or information that the parties wish to share with one another for certain purposes but wish to restrict access to. When discussing confidential work projects with individuals outside the company, an NDA is the appropriate legal instrument to ensure that the sensitive information is not disclosed to unauthorized third parties, thereby protecting the company's intellectual property and trade secrets.
