Browser Lockdown for Online Exams: What It Can and Cannot Do

For online exam monitoring, universities and certification providers use AI proctoring Software that is designed to restrict the use of unauthorized websites, applications, and browsing functions. These restrictions are known as a Lockdown Browser.

Depending on the exam cheating prevention system and its configuration, it may prevent candidates from opening other websites, switching applications, copying & pasting text, printing or saving exam content, or using specific keyword shortcuts.

To maintain online exam security, the lockdown browser process begins before the candidate starts the exam. The system monitors the required restrictions, and the candidate installs or launches the approved browser or application.

A lockdown browser reduces the opportunity to use and explore unauthorized materials or websites during a remote assessment to conduct a fair exam and fulfill the security measures.

• Restrict Website Access – It helps to block navigation to unauthorized websites or domains.
• Limit Application Switching – Prevents the system from switching tabs while the exam is active.
• Disable Copy & Paste – Restrict the copy and paste feature, ensuring the candidate does not cheat.
• Saving and Screenshots – To safeguard exam content, it can restrict saving and screenshots.
• Disable Selective Shortcuts – Blocks configured keyboard commands that could interrupt or bypass the testing environment.
• Enforce an Approved Exam Browser – Requires candidates to use the designated software rather than an ordinary browser.
• Apply device checks - Some tools can detect specified conditions, such as virtual-machine use or unsupported configurations.

Whether you choose an automated proctoring system, live proctoring software, or AI+ Human hybrid proctoring software, note that a lockdown browser can strengthen controls on a device, but it cannot independently eliminate every possible way to gain unauthorized access. Thus, institutions need to be realistic about online exam security.

1. It cannot automatically control every external device

The system can restrict browsing on the device on which the candidate is taking the exam. However, if a student uses another laptop, smartphone, or tablet, additional monitoring may be necessary.

2. It does not necessarily monitor the candidate

The lockdown browser cannot monitor candidate behavior during the exam and generate alerts. To analyze behavior issues, separate monitoring is required that can use a webcam and microphone.

3. It does not verify the candidate's identity

The lockdown browser cannot perform identity checks and ensure that the registered person is taking the exam. For that, use comprehensive exam monitoring software.

4. It cannot guarantee that all attempts to bypass restrictions will fail

 Security depends on the implementation, device permissions, operating system, configuration, and possible attack methods.

5. It cannot independently determine academic misconduct

A technical restriction or software alert is not automatic proof that a candidate intended to cheat. Institutions should review the available evidence and provide a fair process for resolving technical issues or disputed incidents.

• Candidates can reduce avoidable technical problems by preparing ahead of time.
• Download the required browser from the institution’s official link.
• Confirm that the operating system and device meet the stated requirements.
• Close unnecessary applications and follow the exam provider's setup instructions.
• Check camera, microphone, and screen permissions if the exam also requires proctoring.
• Complete a practice test if one is available.

Conclusion

A lockdown browser is a useful component of online exam security because it limits access to selected websites, applications, and device functions during an assessment. However, it should not be presented as a complete solution to online cheating.

For universities, certification bodies, and recruitment teams, the stronger approach is to match browser restrictions to the assessment, combine them with appropriate safeguards where necessary, test accessibility and technical reliability, and review incidents fairly.
