v3.2The Sentinel Agent is built in high-performance Rust to ensure zero impact on user productivity. Unlike legacy antivirus and EDR agents that consume gigabytes of RAM and slow down user laptops, the Sentinel service uses less than **15 MB of RAM** and consumes less than **0.2% CPU** during active monitoring.
The 4 Core Monitoring Modules
Tracks active foreground windows, process start and exit times, parent process IDs, and calculates exact user active/idle durations. Does not record keystrokes.
Note
Built-in Safety Watchdog
Sentinel includes an automatic safety guard. If the client machine enters low power mode or undergoes extreme CPU stress, Sentinel automatically throttles its polling to preserve user battery and responsiveness.
