The CONFIDENTIAL: NEED_TO_KNOW label is for information that is proprietary to the company, has a higher level of sensitivity than INTERNAL_USE_ONLY, and has a more limited audience. Distribution is limited to employees who need to know the information. Other people who need to know the information and who have signed nondisclosure agreements might also be in the audience.
For example, if only the group of people working on a particular project should view certain information, then NEED_TO_KNOW should be used on that information. Whenever information must be restricted to a particular group, the name of the group needs to be specified on the paper version of the information.
Including the name of a group in the CONFIDENTIAL: NEED_TO_KNOW label makes it clear that the information must not be given to anyone outside of the group. Information with this label cannot be sent over the Internet, but it can be sent over email within the company.
Suitable use of the NEED_TO_KNOW label includes the following:
Product design documents
Project details
Employee Status Change form
