A Non-Disclosure Agreement (NDA), also known as a Confidentiality Agreement, is a contract used to outline confidential material, knowledge, or information shared between two parties. This disclosure is usually made for the purpose of a financial transaction or other type of business arrangement, and no one party may use it without permission from the other party. An NDA outlines the specific details of the sensitive information being shared and sets guidelines on how it is to be used, distributed, and protected. NDAs can be enforceable in court if needed and protect any confidential information discussed during a project, meeting, or negotiation.
