Browser lockdown has blind spots.

Browser lockdown controls what happens inside the browser. AI cheating tools operate outside it — as desktop apps, GPU overlays, and audio assistants. Zero Assist monitors the OS process layer, where these tools actually run.

What does browser lockdown actually prevent?

Browser lockdown tools restrict candidates to a controlled browser window — blocking tab switching, copy-paste, and navigation away from the assessment page. This approach was designed for a world where cheating meant opening a second browser tab. Modern AI cheating tools never need to open a second browser tab. They run as desktop processes, GPU overlays, and audio pipes that browser lockdown has no visibility into whatsoever.

Browser lockdownWhat it controls

  • 01Blocks navigation to other browser tabs ✓
  • 02Prevents copy-paste in the assessment window ✓
  • 03Cannot see desktop applications running outside the browser ✗
  • 04Cannot detect GPU overlays rendering outside the browser window ✗
  • 05No visibility into audio-based AI tools using the microphone ✗

Zero AssistWhat it adds

  • 01OS process monitoring catches every desktop AI tool regardless of window state
  • 02Detects GPU overlays (Cluely, Final Round AI) by process name
  • 03Microphone access monitoring catches audio AI tools
  • 04VM and remote desktop detection covers session hijacking

How to cover what browser lockdown leaves open.

Zero Assist is designed to complement browser lockdown — not replace it. Together they cover every known cheating vector: browser lockdown handles in-browser behaviour, Zero Assist handles everything that runs outside the browser at the OS level.

Every application on a computer — browser, desktop app, overlay, IDE plugin — runs as an OS process. Zero Assist monitors this list continuously. It detects AI cheating tools the moment they start running, before the first AI-generated answer reaches the candidate.

Cluely and Final Round AI render as GPU overlays outside the screen capture region. They are completely invisible to browser lockdown. Zero Assist detects them by their OS process — the one layer they cannot hide from.

Parakeet AI and LockedIn AI listen through the microphone and deliver answers via earpiece. No browser tab involved. Detected by OS process monitoring and microphone access flags.

Virtual machine environments and active remote desktop sessions identified before the interview starts — catching session hijacking attempts.

Windows UI Automation reads the actual live URL in any browser — including tabs that browser lockdown cannot control because they were opened before lockdown activated.

All hidden AI tools that operate outside the browser: Interview Coder, Blackbox AI, ChatGPT desktop, Cluely, Parakeet AI, and more — covered by the same agent.

Browser lockdown vs OS-level monitoring.

Browser lockdown questions answered.

Cover what browser lockdown can't see.

Zero Assist monitors at the OS level — detecting AI tools that run outside the browser and are completely invisible to browser lockdown alone.

Browser lockdown for online tests restricts what candidates can do inside a web browser during an assessment. It cannot detect AI cheating tools that operate outside the browser — invisible GPU overlays, audio-based AI assistants, desktop AI applications, and virtual machine environments. Zero Assist monitors at the OS process level and detects all of these vectors that browser lockdown cannot see.

What Is Browser Lockdown for Online Tests?

Browser lockdown software locks the candidate's browser during an online test, preventing navigation to other tabs, disabling copy-paste, and restricting access to other websites. This was effective when cheating meant opening a second browser tab. Modern AI cheating tools — Cluely, Parakeet AI, Final Round AI, Interview Coder — do not need a browser tab. They run as desktop applications, GPU overlays, IDE extensions, or audio pipes that browser lockdown has no visibility into at all.

Is Browser Lockdown Enough to Prevent Cheating?

Browser lockdown is not sufficient to prevent cheating in modern technical interviews. The most prevalent AI cheating tools are specifically designed to operate outside the browser and remain invisible to browser-based monitoring. Cluely renders as a GPU overlay outside the screen capture region. Parakeet AI runs as a background audio process with no window. Interview Coder runs as a stealth desktop app. None of these tools are affected by browser lockdown in any way.

How Does Zero Assist Complement Browser Lockdown?

Zero Assist monitors the OS process list directly — the layer where every application on the computer must exist to run. When a known AI cheating tool is detected, a WebSocket alert fires to the interviewer dashboard in under 500 milliseconds. Used alongside browser lockdown, it covers all known cheating vectors: browser lockdown handles in-browser behaviour, Zero Assist handles everything that runs at the OS level outside the browser.

Frequently Asked Questions

What is browser lockdown for online tests?

Browser lockdown for online tests restricts what candidates can do within a web browser during an assessment — blocking navigation to other tabs, preventing copy-paste, and sometimes disabling right-click. It does not prevent the use of desktop applications, invisible GPU overlays, audio-based AI tools, or remote desktop sessions running alongside the browser.

Is browser lockdown enough to prevent cheating in technical interviews?

Browser lockdown is not sufficient to prevent cheating in modern technical interviews. AI cheating tools like Cluely, Final Round AI, Parakeet AI, and Interview Coder all operate outside the browser — they run as desktop processes, GPU overlays, or audio assistants that browser lockdown has no visibility into.

What does browser lockdown miss that Zero Assist catches?

Browser lockdown misses any AI tool that operates outside the browser: invisible GPU overlays (Cluely, Final Round AI), audio-based AI tools (Parakeet AI, LockedIn AI), stealth desktop apps (ChatGPT desktop, Interview Coder), and virtual machine or remote desktop environments. Zero Assist monitors the OS process list directly and detects all of these.

Can browser lockdown and Zero Assist be used together?

Yes — the two approaches are complementary, not mutually exclusive. Browser lockdown restricts in-browser behaviour. Zero Assist monitors at the OS level and covers everything browser lockdown cannot see. Using both provides the broadest coverage across all known cheating vectors.

Why do candidates cheat despite browser lockdown?

Browser lockdown only controls the browser window. Candidates cheat by running AI tools outside the browser — as desktop applications with no visible window, as IDE extensions, or as audio assistants operating through the device microphone. These tools are specifically designed to be invisible to browser-based monitoring. OS-level monitoring like Zero Assist is required to detect them.
