AI Overlay for Kryterion Webassessor - CompTIA, CISSP, Salesforce on Mac
Kryterion, founded 2001 in Phoenix Arizona, operates Webassessor and the Sentinel Secure lockdown app. CompTIA online testing, ISC2 CISSP retakes, Salesforce, ITIL, Atlassian, and many Linux Foundation certifications deliver through Webassessor with Sentinel Secure handling the host lockdown.
Webassessor is Kryterion test-delivery platform; Sentinel Secure is the companion lockdown application a candidate downloads on Mac before any online-proctored exam. Sentinel Secure prevents application switching, blocks new browser tabs and windows, disables copy and paste, blocks printing, and blocks the screenshot hotkeys. None of that touches the underlying macOS window-privacy mechanism. Sentinel Secure captures the screen through the standard ScreenCaptureKit pipeline on Sonoma+ and streams it to a Kryterion proctor through Kryterion in-house proctoring console.
Sentinel Secure enumerates running processes against an internal blacklist of remote-desktop and screen-share apps. Fracture uses a randomized process name per build.
No. Sentinel intercepts the Cmd-Shift-3 and Cmd-Shift-4 screenshot shortcuts at the Cocoa event level. Fracture uses a Carbon global hot-key registered with RegisterEventHotKey.
Yes. CompTIA offers online sittings through both Pearson VUE OnVUE and Kryterion Webassessor depending on exam.
ISC2 historically used Pearson VUE for CISSP and now uses Pearson VUE plus a Kryterion fallback for retakes in certain regions.

Fracture runs a native floating overlay that sets the macOS window privacy flag. It is 100% excluded from screen capture feeds, window lists, and proctor recordings.
