A Non-Disclosure Agreement (NDA) is a legal agreement 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 or by third parties. NDAs can be mutual or unilateral, depending on whether both parties are disclosing or just one. NDAs are commonly used in business and employment settings to protect sensitive information such as trade secrets, confidential data, and proprietary information. Types of Non-Disclosure Agreement include: • Unilateral NDA: This is an NDA signed by only one party who wishes to disclose confidential information to the other party. • Mutual NDA: This is an NDA signed by both parties who wish to exchange confidential information. • One-way NDA: This is an NDA signed by one party to protect confidential information shared with the other party. • Confidentiality Agreement (CA): This is a type of NDA that is used to protect confidential information shared between two parties. • Proprietary Information Agreement (PIA): This is a type of NDA that is used to protect proprietary information shared between two parties.
