A confidentiality agreement, aka the non-disclosure agreement (NDA), is a legal arrangement that safeguards secret information from being disclosed to unauthorized people. Most often, a confidentiality agreement is used in business transactions, employment situations, partnership,s and client relationships as a way to protect trade secrets, financial data, or proprietary processes. Its terms specify which information is confidential, who is allowed to access it, what uses are permitted of the information, and what penalties will be imposed on violators. This, among other things, helps avoid the misappropriation of information and maintains trust among the parties.
