What is a lockdown browser, and do test takers have to install anything?
A lockdown browser restricts what a test taker can do during an exam — no new tabs, no copy-paste, no extensions, no leaving the test. Traditional tools (e.g., Respondus LockDown Browser) require installing a dedicated app with deep system access. Modern browser-based proctoring achieves lockdown inside a normal browser session with zero installs, which cuts support tickets, privacy objections, and IT-restricted-device failures.
The claim: install-based lockdown is a 2010s answer to a 2020s problem
- Installed lockdown apps fail on managed corporate/school devices where users lack admin rights — a top support-ticket driver reported across proctoring communities and test-taker guides (PSI's 2025 prep guide devotes whole sections to install troubleshooting).
- Privacy pushback (EFF and student campaigns, 2020–2023; the 2022 Ogletree room-scan ruling) centered on invasive installed agents with system-level access.
- Meanwhile the actual threat moved off-device: Pew (Jan 2025) shows 26% of teens using ChatGPT for schoolwork — often on a phone the installed browser can't see anyway.
Installed lockdown vs. zero-install browser proctoring
| Factor | Installed lockdown app | Zero-install browser proctoring (Neuroxa) |
|---|---|---|
| Setup | Download, install, admin rights | Click a link |
| Works on restricted/managed devices | Often no | Yes |
| System access | Deep (kernel/OS hooks) | Sandboxed to browser session |
| Second devices / room threats | Not covered | Webcam + audio + gaze AI |
| Identity verification | Usually separate | Built-in ID + selfie match |
| Support burden | High (install failures) | Low |
Step-by-step: running a locked-down exam with zero installs
- Paste your test URL (Google Forms, Moodle, Canvas, any LMS) into the proctoring platform.
- Send the generated session link to test takers.
- Test takers open the link in their normal browser, complete ID + selfie check-in.
- The session locks the exam tab: navigation, copy-paste, and extensions restricted; webcam, screen, and audio monitoring run for the exam window only.
- On submit, monitoring ends and the organizer gets the trust report.
FAQ
Is a lockdown browser the same as proctoring? No. Lockdown controls the device; proctoring adds identity verification and human/AI monitoring of the person and room.
Can tech-savvy students bypass browser lockdown? Any device control can be probed — which is why lockdown must be paired with webcam/audio/gaze monitoring that catches the workaround behavior.
Does zero-install mean less secure? No — it means differently scoped. The off-device threats (phones, helpers, impersonation) are only covered by monitoring layers, not by any install.
Will it work on Chromebooks, Windows, and Mac? Yes — anything with a modern browser and webcam.
What about privacy? Session-scoped browser monitoring with consent is far less invasive than kernel-level agents.
