LockDown Browser is a custom secure browser that prevents test-takers from accessing external resources during exams. It disables features like printing, copying, task switching, screen capture, and launching other applications. Paired with Respondus Monitor, it enables AI-triggered webcam recording for remote proctoring. The suite integrates tightly with major LMS platforms like Canvas, Moodle, Blackboard, Brightspace, Schoology, and Sakai
