Where Lockdown Browsers Fall Short — and How We Solve It

Traditional lockdown solutions introduce friction at every step. TestInvite removes each failure point without reducing control.

Exam day setup failures

Candidates can't start because of installation errors.

No installation, no failures

The lockdown runs entirely in the browser. Candidates open a link and start with zero setup.

Candidates switch tabs and apps

Candidates can open new tabs, apps or browsers without being detected in time.

Fullscreen locks them in

Any attempt to open new tabs, other apps, or browser switching is detected immediately.

No visibility into violations

You know something happened, but not for how long, or what the candidate was doing.

Every event logged in context

Violations are recorded with a timestamp, duration, and the question on screen.

Disconnections end the exam

A brief network drop ends the session, causing lost progress and invalid results.

Disconnections don't end the exam

Auto-resuming keeps sessions active so candidates can reconnect and continue.

Browser Lockdown Controls

Fine-tune exactly what candidates can and cannot do during an exam session.

Fullscreen mode

The exam forces itself into fullscreen on start. Exit attempts are warned and logged immediately.

New tabs or windows

Candidates cannot open other browser tabs, windows, or switch to a different browser.

External applications

Switching to messaging apps, screen-sharing tools, or any other application is detected and logged.

Copy/paste & text selection

Candidates cannot copy content, highlight text, or paste anything into or out of the exam.

Right-click & print

Context menus, developer tools, and print dialogs are all disabled.

Browser translation

Built-in translation features are disabled. Exam content stays in its original language.

Violation Threshold Settings

Define exactly when the system should intervene based on candidate behavior.

Number of violations

Specify how many violation events are allowed before the exam is automatically ended to prevent repeated rule breaches.

Seconds per violation

Set how long a single violation can last before it is considered a threshold breach and counted toward the total limit.

Total violation time

Define the maximum accumulated time a candidate can spend outside secure mode before action is triggered.

File upload window

Specify how long candidates can use the file selector during uploads before it is counted as a violation, ensuring legitimate upload actions are not flagged.

Media permission window

Specify how long candidates can remain on camera or microphone permission prompts before it triggers a flag.

Session Tracking & Control

Every security event is logged with the exact timestamp, the violation type, how long it lasted, and which question the candidate was on. You can reconstruct exactly what happened during any exam session.

Auto-flagging (no removal)

Instead of terminating the exam, the system silently flags suspicious activity in the background. You review flags after the session; candidates are never notified. Useful when you want data without disrupting the exam flow.

Auto-resuming

If a candidate disconnects mid-exam, the session doesn't terminate immediately. You define the reconnection window and the maximum number of reconnection attempts. Reduces exam disruptions caused by connectivity issues rather than misconduct.

Browser Based vs. Installation Based Lockdown

TestInvite removes the friction of traditional desktop lockdown software without sacrificing control.

Installation-based lockdown TestInvite browser-based

Fails on corporate or managed devices where installation isn't permitted Works on shared, corporate, and managed devices where installation is blocked
Generates high IT support volume at scale Scales to thousands of concurrent exam takers without IT involvement
Elevated system privileges create privacy and compliance exposure No access to system processes or personal data — GDPR safe
