What's the difference between browser lockdown and full desktop lockdown?
TL;DR: Browser lockdown restricts one browser tab — it blocks tab-switching and copy-paste inside that tab, but a second device or a desktop AI app sitting outside the browser is invisible to it. Full desktop lockdown (or a paired webcam+behavior layer) restricts the whole machine, but usually requires an install. Neuroxa's approach: zero-install browser lockdown paired with webcam, gaze, and audio monitoring, so the second-device gap gets covered without forcing a download.
Claim
"Lockdown browser" and "secure exam environment" are not the same product, and treating them as interchangeable is exactly how second-device cheating slips through.
Evidence
- HackerEarth's 2026 cheating-tactics research states plainly: "a traditional lockdown browser only controls the browser tab, leaving the rest of the desktop unprotected," which is why desktop-app-based tools exist as a separate layer.
- Respondus's own FAQ confirms LockDown Browser "does not detect external device use or verify a test taker's identity" — by design, not by flaw.
- The dominant 2026 cheating tactic, per the same research, is running an LLM in a separate window or device specifically because it defeats browser-only restrictions.
Comparison: browser lockdown vs full desktop lockdown vs zero-install layered proctoring
| Layer | Install required | Blocks tab-switching | Blocks second device/app | Verifies identity |
|---|---|---|---|---|
| Browser lockdown only | No | Yes | No | No |
| Full desktop lockdown app | Yes | Yes | Yes | No (unless paired) |
| Zero-install layered proctoring (webcam + gaze + audio) | No | Yes (via full-screen enforcement) | Partial, via behavior/audio flags | Yes |
Step-by-step: choose the right lockdown level for your assessment
- Low-stakes quiz, low cheating incentive: browser lockdown alone may be enough.
- High-stakes certification or hiring assessment: pair browser lockdown with webcam + audio + gaze monitoring.
- BYOD population that can't install software: choose a zero-install layered tool over a desktop app.
- Managed devices (school/company laptops): a full desktop lockdown app becomes viable since IT controls the install.
- Always test your chosen combination against the second-device scenario before go-live.
FAQ
Does a desktop lockdown app fully solve the second-device problem? Mostly, for the primary device — but it still can't see a phone in the candidate's lap. Only webcam/gaze monitoring catches that.
Why not just require a desktop install for everyone? Installs create friction, IT-support tickets, and access barriers for candidates on locked-down work laptops or Chromebooks — a real problem for hiring assessments and open-enrollment courses.
Is zero-install proctoring less secure than a desktop app? Not necessarily. Pairing browser-level lockdown with continuous webcam, gaze, and audio analysis closes most of the same gaps without the install friction.
