AI Overlay for Kryterion Webassessor on Mac
Kryterion administers a long list of IT and professional certifications through Webassessor (the test platform) and Sentinel Secure (the remote-proctoring app). Common Webassessor exams include AWS Certified, Salesforce certifications, and ITIL.
Sentinel Secure is a notarized macOS app that takes over the screen during the exam, streams to a live proctor, and records for asynchronous review. Its capture path is straightforward: ScreenCaptureKit on macOS 12.3+ for the screen, AVFoundation for webcam and microphone. Both APIs treat window privacy as a hard filter, not a hint. Fracture sets the flag on its overlay; the resulting frames Kryterion receives lack the overlay region, regardless of whether the proctor is reviewing live or after the fact.
Yes. It enumerates running apps and may flag known proctor-bypass tools. Fracture uses a randomized innocuous app name per build, so the scanned name is benign.
It gives you access to ChatGPT or Claude during the exam window. Whether you pass depends on your prep; using AI on a cert exam violates the candidate agreement.
Sentinel disables external monitors during the exam. The overlay sits on your built-in display, no extra monitor needed.

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.
