Procta Secure Browser (PSB): the lockdown exam browser
Procta Secure Browser (PSB) is Procta's own proprietary lockdown exam browser — designed, built, and maintained in-house. Students install it on Windows or macOS to sit a proctored exam: it locks the screen to the test, blocks the ways students cheat on a normal browser, and runs AI proctoring on-device — so camera frames are analysed on the student's own PC and no raw video is ever recorded or uploaded.
True lockdown
Fullscreen lock, copy/paste and right-click blocked, keyboard shortcuts and app switching disabled, screenshots and screen-sharing suppressed for the duration of the exam.
Environment checks
Detects virtual machines, remote-desktop tools (AnyDesk, TeamViewer, RDP), multiple monitors, and known cheat utilities — and flags or blocks the session before it starts.
On-device AI
Face, gaze, and object detection run inside PSB on the student's machine. Only violation events and risk scores leave the device — never the video feed. Bandwidth-light and DPDP-friendly.
Privacy by design
No biometric templates stored, no video retained. PSB pairs with the student's phone as a second room camera, and answers autosave locally so a network drop never loses work.
How PSB compares to a normal browser
- A normal browser lets students open notes, switch tabs, screen-share to a helper, or run answers through an AI in another window. PSB closes every one of those doors.
- Unlike cloud proctoring that streams webcam video to a server, PSB does the AI analysis locally — faster, cheaper on bandwidth, and far easier to defend under DPDP.
- Cross-platform: one PSB build for Windows, one for macOS. Students download once and reuse it for every exam you assign.
