A confidentiality agreement (NDA), sometimes referred to as a confidentiality agreement, is a written contract between two parties (persons or entities) that prohibits the exchange of confidential information disclosed to them. In short, if you are asked to sign an NDA, you promise to keep secret all sensitive information that is shared with you and not to share it with others. If you are the NDA exhibitor, ask someone else not to share information that you can share with them. We recommend that a lawyer verify the staff trust agreement before you or the employee is signed and the employee confidentiality agreement is signed. 1. . .
