A Connecticut non-disclosure agreement is a contract that prohibits the sharing of trade secrets and other proprietary information with any third party. Trade secrets are valuable because they are unavailable to the general public, and disclosing them may cause harm to the company or its employees, contractors, clients, and investors.

An NDA is used in a business context whereby a company wishes to hand over confidential information to another party (i.e., an employee, client, consultant, investor, etc.) but wants to ensure it is safeguarded from misuse or dissemination. This contract can also be used in situations where both parties are sharing information with each other; this is called a mutual agreement.
