Respondus LockDown Browser is a custom browser that locks down the testing environment within Canvas. When students use Respondus LDB they are unable to print, copy, go to another URL, or access other applications. When an assessment is started, students are locked into it until they submit it for grading. It is available for both Windows and Mac.
