A confidentiality agreement, often called a non-disclosure agreement (NDA), is a legal contract between two or more parties. It ensures that any sensitive information shared during their relationship remains private and is not disclosed to others. These agreements are commonly used in business settings to protect trade secrets, proprietary information, or any confidential data. When parties sign a confidentiality agreement, they agree on the specific information that must be kept secret and the duration of the confidentiality obligation. Breaching this agreement can lead to legal consequences, including financial penalties or lawsuits, to protect the interests of the affected party.
