Block What Doesn't Belong.
Allow What Does.

Sentinel doesn't just watch, it acts. Every camera access, mic activation, USB plug-in, and Bluetooth pairing requires your explicit approval. Unknown = blocked.

Camera Guard

Every app that touches your camera must be approved. Approve & remember trusted apps, or block them forever, blocked apps are killed the instant they try again. No recording possible.

APPROVE / BLOCK

Mic Shield

Real-time microphone access control. Approve trusted apps once and never see them again. Block rogue apps and they are killed on contact, before a single frame of audio is captured.

APPROVE / BLOCK

Network Intel

Every TCP and UDP connection mapped to its exact process. Resolved hostnames, live traffic bytes, port scanner, LAN device discovery, and one-click process termination.

INSPECT / KILL

USB Control

No USB device connects silently. Every plug-in triggers an approval prompt, allow and remember it, or block it forever. Blocked storage devices are automatically force-ejected on every reconnect.

APPROVE / EJECT

Bluetooth Control

Every Bluetooth pairing goes through Sentinel. Approve trusted devices and they connect silently from then on. Block unwanted devices and they are disconnected the instant they try to pair.

APPROVE / DISCONNECT

App Lock

Sentinel locks behind Touch ID or Apple Watch on every launch. Monitoring never pauses, but your approval history and threat data stay completely private until you authenticate.

ALWAYS PROTECTED

Approve from
Your Wrist.

When Sentinel needs your approval, a double-click of the Apple Watch side button is all it takes. No typing, no unlocking, no reaching for the keyboard — just your wrist.

  • Camera & microphone access requests
  • USB device reconnects requiring re-approval
  • Unlocking the Sentinel main window
  • Disabling any monitoring service
Double-click side button → approved instantly. No Mac touch required.

// how it works

Approve Once.
Block Forever.

01 //

Something Tries to Access Your Hardware

An app activates your camera, mic, USB port, or Bluetooth, Sentinel intercepts it in real time using CoreMediaIO, CoreAudio, IOKit, and IOBluetooth. The action is held pending your decision.

02 //

You Approve or Block

A prompt surfaces with the app name, bundle ID, and what it wants. Hit Approve & Remember to whitelist it silently from now on. Hit Block Always and it is denied on the spot, and killed or ejected every time it tries again.

03 //

Sentinel Remembers. No Repeat Prompts.

Approved apps connect silently forever. Blocked apps are terminated or ejected automatically, no alert, no confirmation. Your permissions are stored securely in the macOS Keychain, never in plaintext.
