Sentinel is a cross-platform exam security system. It supports all modern web browsers (Chrome, Firefox, Safari, Edge) for web-based exams, and offers dedicated native applications for Android and iOS devices.

Sentinel uses the student's device camera and microphone to perform automated monitoring. The system checks for gaze deviations (looking away from the screen for extended periods) and flags audio anomalies (human voices or sudden noises) in real-time, notifying the proctor panel.

No, students can take exams directly in their web browser without any installation for standard web proctoring. For enhanced mobile security, students can download the lightweight Sentinel app from the Google Play Store or iOS App Store, which guides them through a simple permission check.

Privacy is our top priority. Sentinel only accesses the camera, microphone, and device state during active exam sessions. No data is recorded or transmitted before the exam starts or after it is submitted. All data is securely processed in compliance with institutional privacy standards.

Yes. On web browsers, Sentinel monitors focus state and alerts if the student switches tabs or windows. When using our native mobile apps, Sentinel locks the screen to the exam application, preventing unauthorized multitasking, screenshots, and screen sharing.

Proctors access a centralized dashboard where they can see live status indicators, flagged alerts, and real-time activity logs for all active students. This allows proctors to address integrity flags immediately or review session logs post-exam.
