Digiexam vs OpenLock

Digiexam is online exam software for schools, covering exam creation, delivery, grading, and cheating prevention. Teachers can create or reuse exams, monitor progress in real time, and grade by question or student. Digiexam Lockdown restricts student devices to the learning management system and approved resources. Accessibility settings include spell check, text-to-speech, translations, and extended time.

Online proctoring options include optional ID verification, automated or in-person monitoring, mobile camera support, open chat, and credibility reports. LTI integrations are available for Canvas, Moodle, itslearning, Blackboard, Sakai, Brightspace, and Blackbaud, with account provisioning, SSO, QTI 1.2 and Common Cartridge imports, deep linking, and automatic grade sync. Digiexam lists closed-source code, third-party security audits, penetration tests, EU and US servers, and GDPR compliance. The company states its cloud platform has 99,9% uptime, supports offline exams, and autosaves every 10 seconds.

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.
