Inspera Integrity Browser vs OpenLock

Inspera Integrity Browser is a desktop lockdown application for online assessments. It controls which applications, device content and external resources candidates can access during an exam. Institutions can use strict lockdown or permit selected materials such as specified PDFs and URLs. With Inspera Assessment, the browser can block copying and pasting into or out of the assessment and prevent screenshots. Inspera Proctoring integrations can add video, audio and screen recording for invigilators. Institutions may enable up to five third-party applications, although service-desk activation and IIB 1.16.16 or newer are required on Windows, and the option is unavailable on macOS. Students download the application through their institution’s Inspera portal; it stays inactive until an assessment is configured. It runs on Windows and macOS, not Linux, Chromebooks, virtual machines, tablets or phones. IIB is a paid add-on to Inspera Assessment, with pricing on request.

OpenLock is a free, open-source lockdown exam browser built natively for Linux. It aims to provide Safe Exam Browser-style controls, but the project states that it is not exam-ready because SEB key derivation is not byte-exact and the LMS handshake currently fails. It parses .seb files and sends Browser Exam Key and Config Key headers, although those keys do not yet match an LMS handshake. Kiosk mode uses fullscreen takeover through X11 or Wayland/Cage. A process guard monitors and terminates prohibited software such as screen recorders, virtual machines, and remote desktop tools. Input controls block shortcuts including Alt+Tab, Alt+F4, Ctrl+C, and PrintScreen, while browser hardening disables developer tools, downloads, right-click, console access, and drag-and-drop. Security measures include URL filtering, cgroups v2 isolation, VM/debugger/hypervisor detection, optional self-hash checks, and an off-the-record profile. Moodle, Canvas, and Blackboard adapters are listed but not validated live.
