# Define Endpoint Application elements

Use Endpoint Application elements for access control in the SMC.

Endpoint Application elements contain information about the applications used by Forcepoint One Endpoint clients. The elements are delivered in dynamic update packages, but you can also create elements manually. If you upgraded the SMC, you might have legacy Executable elements. We recommend using Endpoint Application elements instead.

Endpoint Application elements are categorized by usage type with Tag elements. You can use a Tag in a policy to allow or block the use of a category of applications, such as instant messaging applications.
