Develop system extensions that enhance user security.


Endpoint Security is a C API for monitoring system events for potentially malicious activity. Your client, which you can write in any language supporting native calls, registers with Endpoint Security to authorize pending events, or receive notifications of events that have already occurred. These events include process executions, mounting file systems, forking processes, and raising signals.

Develop your system extension with Endpoint Security and package it in an app that uses the SystemExtensions framework to install and upgrade the extension on the user’s Mac.
