Red Canary Mac Monitor is a feature-rich dynamic analysis tool for macOS that leverages our extensive understanding of the platform and Apple’s latest APIs to collect and present relevant security events. Mac Monitor is practically the macOS version of the Microsoft Sysinternals tool Procmon. Mac Monitor collects a wide variety of telemetry classes, including processes, interprocess, files, file metadata, logins, XProtect detections, and more—enabling defenders to quickly and effectively analyze enriched, high-fidelity macOS security events in a native, modern, and customizable user interface.
