Secure Lockdown Browser for Online Exams
A browser-based lockdown that enforces fullscreen, blocks external access, logs every violation, and keeps sessions alive through disconnections.
Enforce a controlled exam environment
Control every action inside the exam environment. Browser lockdown covers the full surface area of what a test-taker can do inside the browser.
Define violation rules and thresholds
Configure exactly when a violation counts, how much tolerance to allow, and when to end the exam automatically.
Limit number of violations
Set the maximum number of violation events allowed before the exam is automatically terminated.
Limit seconds per violation
Define how long a single violation can last. Any violation exceeding this duration counts as a threshold breach.
Limit total violation time
Specify the maximum accumulated violation time across the entire session before the exam ends.
Window for file selection
Limit how long participants have to select and upload files, so legitimate actions are allowed while delays are flagged as violations.
Window for media permission prompts
Limit how long participants can take to grant media permissions or complete required actions like taking a photo, so delays are flagged as violations.
Not every violation indicates misconduct. Pop-ups and system alerts for emails or software updates can trigger a full-screen exit without any action by the participant.
Manage violations and disconnections without disrupting the exam
Two modes that give you control over how violations are handled without disrupting the exam flow.
Run secure exams in a browser-based lockdown
No downloads, no plugins, no system-level installations. Participants open a link and the exam begins.
Participant opens the exam link
No software to install or configure. The lockdown environment initializes directly within the browser on any operating system.
Fullscreen activates on start
When the participant clicks Start, the system requests fullscreen access. The exam proceeds only after the participant grants this permission.
Continuous monitoring begins
JavaScript listeners watch for fullscreen exits, window focus loss, new tabs, application switches, copy attempts, and more in real time.
Violations are logged in context
Each event is recorded with a timestamp, the violation type, its duration, and which question the participant was viewing at the time.
Rules determine what happens next
You define violation thresholds. When limits are exceeded, the system issues an on-screen warning or terminates the session automatically.
Admins review the full audit trail
After the session, a detailed activity log shows every breach, its duration, and whether automatic termination was triggered.
Browser-based vs. installation-based lockdown
The difference is not just convenience. It affects privacy, compliance, and whether your exam can actually run.
Combine lockdown with proctoring for stronger exam integrity
Browser lockdown controls what participants can do inside the exam environment. Online proctoring adds visibility into who is taking the exam and what happens around them through webcam, screen, and audio monitoring.
Use them together to restrict external access, monitor suspicious behavior, and review evidence after the session.
