Lockdown Browser Tools for Secure Online Exams

Update: Sep 7, 2026 · 24 apps reviewed

Lockdown browser software is designed to keep online exams tightly controlled by limiting what students can open, copy, print or share during a test. The strongest options balance strict exam protection with smooth setup, reliable webcam monitoring and low system overhead so the test environment does not become the problem. When choosing a tool, compatibility with your learning platform, device support and privacy safeguards matter just as much as the security features. Good exam browsers reduce cheating opportunities without creating unnecessary friction for legitimate test-takers.

Frequently asked questions (FAQs) about this topic

What does a lockdown browser actually block during an exam?

A lockdown browser typically restricts switching to other apps, opening new tabs, taking screenshots, copying text and printing. Some versions also disable right-click menus, keyboard shortcuts and access to external resources. The exact restrictions depend on the exam platform and the settings chosen by the instructor.

Do lockdown browsers work on personal laptops and Chromebooks?

Many do, but device support varies by platform and school policy. Some tools run on Windows and macOS only, while others also support Chromebooks or require a companion app. Always check the exam requirements before test day to avoid compatibility issues.

Can a lockdown browser detect cheating with a webcam?

Some exam browsers include webcam monitoring, room scans or browser activity tracking, but not all of them do. These features can help flag suspicious behavior, yet they are usually part of a broader proctoring setup. They do not replace instructor oversight or secure exam design.

Is a lockdown browser the same as online proctoring software?

No. A lockdown browser mainly controls what the student can do on the device during the exam. Proctoring software adds monitoring features such as webcam recording, identity checks or live supervision. Many institutions use both together for higher-stakes assessments.
