What term is used to describe sensitive project information that should not be disclosed outside the office?

The term that best describes sensitive project information that should not be disclosed outside the office is "confidential information." This designation encompasses any data or information that is restricted to a certain group of individuals within an organization, especially if its disclosure could harm the business or give competitors an advantage.

Confidential information is often protected by internal policies and, in some cases, by legal agreements to ensure that employees and stakeholders understand the importance of maintaining privacy concerning sensitive company matters. Examples of confidential information include project details, financial records, personal employee information, and proprietary methodologies.

While "trade secret" might seem relevant, it specifically refers to a type of confidential information that provides a business edge and must meet certain criteria under law to be protected as such. Non-disclosure agreements are legal contracts that prevent individuals from sharing confidential information but do not describe the information itself. "Private data" is a more general term and does not specifically indicate the sensitivity or internal protocols related to project information.
