A Confidentiality Agreement (also known as a Non-Disclosure Agreement or NDA) is a legally binding contract between two or more parties that outlines the confidential information each party is responsible for protecting. The agreement is designed to prevent the unauthorized sharing of sensitive information, such as trade secrets, proprietary information, or other information of a sensitive nature, between the parties involved. The parties may be individuals, businesses, or both, and the agreement outlines the specific information to be kept confidential, the duration of the agreement, and the consequences of a breach of the agreement. There are two types of Confidentiality Agreement: unilateral agreements and bilateral agreements. A unilateral agreement is a one-way contract, meaning only one party is responsible for keeping the information confidential. A bilateral agreement is a two-way contract, meaning both parties are responsible for keeping the information confidential.
