A Wisconsin non-disclosure agreement is a contract involving two (2) parties that restricts one or both from disclosing sensitive, proprietary information. The agreement, also known as an “NDA,” requires the recipient of confidential information to keep it secret until they are released from the contract, or the info becomes public knowledge. An NDA can be used to prevent one party from disclosing the other’s information (a “mutual” agreement) or restrict both parties from disclosing each other’s information (a “unilateral” agreement).
