// macOS Privacy Monitor — v1.0
See Everything. Miss Nothing.
// capabilities
Every sensor. Every connection. Every device. Sentinel watches them all in real time — and kills what doesn't belong.
Detects every app accessing your camera the instant it activates. Block silently or kill the process with one click.
ACTIVE MONITORINGReal-time microphone access detection. Unauthorized apps are flagged immediately — or auto-killed in lockdown mode.
ACTIVE MONITORINGEvery TCP and UDP connection mapped to the exact process. See remote hosts, resolved domains, and kill suspicious traffic.
ACTIVE MONITORINGEvery USB device logged the moment it connects. Identifies device type, vendor, and triggers an alert for unknown hardware.
ACTIVE MONITORINGTracks every Bluetooth device pairing and connection event. Unknown devices surface immediately with a dismissal prompt.
ACTIVE MONITORINGSentinel locks itself behind Touch ID on launch. Monitoring never stops — but your threat data stays private.
ALWAYS PROTECTED// how it works
Sentinel runs invisibly in your menu bar, hooking into CoreMediaIO, CoreAudio, and the network stack to watch every sensor — with zero battery impact.
The moment any app touches your camera or microphone, Sentinel identifies it by process, bundle ID, and parent app — then surfaces an alert in under 500ms.
Allow once, whitelist forever, or add to the blocklist — and next time the app is killed the instant it tries. No alert, no negotiation.
// free. no subscription. no telemetry.
Sentinel is free, open source, and runs entirely on your machine. No cloud. No accounts. No tracking. Just total visibility.
