Comparison Table
Respondus LockDown Browser
educationCustom browser that locks the testing environment by preventing copying, pasting, and screen sharing during online exams.
Course-linked lockdown behavior that activates through instructor assessment delivery, not manual student start steps.
Respondus LockDown Browser enforces assessment posture during a live test session by restricting how examinees can interact with the browser. LMS assessment workflows can trigger the locked browser based on instructor-issued test instructions, which helps align lockdown start and end behavior with course delivery. Administrators can manage policies that control allowed navigation and permitted actions during the assessment session.
A key tradeoff is that the tool focuses on browser lockdown posture rather than broad remote proctoring, so it does not replace identity verification or live human monitoring. It fits situations where assessment integrity depends on limiting navigation and interactions inside the browser for a timed course test.
- +LMS-triggered launch reduces mistakes from ad hoc student instructions
- +Consistent lockdown behavior across managed course sessions
- +Clear assessment mode controls tied to course delivery
- +Admin-side configuration supports repeatable rollout
- –Limited admin visibility into in-session events compared with proctoring suites
- –Lockdown enforcement depends on correct browser installation and setup discipline
- –Fine-grained allowlisting for every workflow edge case can require extra coordination
- –Granular automation and API extensibility options are not a core focus

Best for: Fits when LMS-based courses need browser lockdown during timed assessments with predictable student behavior.
Meazure Learning
enterpriseAssessment delivery and proctoring platform with secure browser lockdown for high-stakes testing.
Assessment-launch lockdown policy orchestration that ties browser constraints to exam session operations.
Meazure Learning supports browser lockdown controls that are exercised during assessment launch, with policy-driven constraints that govern what candidates can access inside the browser session. The setup workflow is geared toward test administrators who manage cohorts, sessions, and exam windows, so lockdown behavior stays consistent across many runs. Integration depth matters because Meazure Learning is typically evaluated in the context of assessment delivery instead of standalone browser hardening.
A tradeoff appears in the deployment model, since organizations often need disciplined policy configuration to match each assessment type and allowed resource set. Meazure Learning fits situations where assessments are run at scale with repeated session orchestration, and lockdown behavior must stay aligned with operational checklists. It is less suitable when only ad hoc, per-test lockdown is required without any assessment workflow governance.
- +Assessment-run focused lockdown policies that stay consistent across sessions
- +Operational workflow alignment for scheduled launches and controlled exam behavior
- +Clear admin intent mapping between exam settings and browser constraints
- +Good fit for scale programs that repeat the same assessment pattern
- –Policy configuration overhead increases with complex allowlist requirements
- –Less ideal for one-off lockdown needs without assessment governance

Best for: Fits when test admins need consistent, policy-driven lockdown across scheduled assessment sessions.
Safe Exam Browser
educationOpen-source browser lockdown environment that restricts access to unauthorized resources during online exams.
Certificate-based lockdown enforces the exam configuration identity during runtime, reducing tampering risk outside the configured posture.
Safe Exam Browser uses the SEB protocol to start and control a hardened browser runtime that blocks common integrity breaks like unauthorized navigation and UI escape attempts. Endpoint governance typically relies on a managed configuration rollout so students receive the same kiosk-style browsing posture each session. The model supports permissive mode for scenarios that need constrained navigation flexibility while still keeping the controlled runtime active.
A tradeoff exists between strict lockdown and usability because any required external app, link, or workflow not captured in the configured rules can break an otherwise valid candidate task. Safe Exam Browser fits best when high-assurance browser posture checks are required and when the assessment team can maintain URL rules and session behavior as curricula change.
- +Certificate-based lockdown ties exam session configuration to a controlled runtime posture
- +Configurable allowlist and blocklist rules prevent unauthorized navigation during active exams
- +Strict mode reduces exit paths and UI behaviors that undermine assessment integrity
- +SEB protocol supports repeatable session launch behavior across managed endpoints
- –Strict lockdown can block legitimate workflows if URL rules are not maintained
- –Integration with proctoring and LMS tooling often depends on external orchestration components
- –Misconfiguration can cause candidate access failures that require fast admin troubleshooting

How to Choose the Right Browser Lockdown Software
What separates options in browser lockdown software is how they enforce allowed and blocked activity, how they handle changes to the browser over time, and how tightly they can be governed and audited in your workflows. In practice, you should compare Enforcement coverage, Allowlist management, and Audit logging before you judge any one product.
Enforcement coverage across browser actions
Why it matters
Enforcement coverage across browser actions determines whether users can route around restrictions by using different UI paths or browser features. If enforcement is uneven, the same rule set can fail in real sessions.
How to check
During a demo session, try navigation to an allowed site, then attempt a few common detours like opening a new tab, using a different navigation method, and accessing links from within the allowed page. Ask the admin to show what happens to those actions under the same policy.
Allowlist management and update workflow
Why it matters
Allowlist management and update workflow affect how quickly you can respond to new training URLs or remove risky destinations. If updates are clumsy or slow, lockdown becomes operational friction.
How to check
Ask to see the workflow for adding and removing a destination while a session policy exists. Test whether changes apply to new sessions only or also to currently running sessions, and whether the product supports staged rollout and rollback.
Policy scope for users, devices, and profiles
Why it matters
Policy scope for users, devices, and profiles matters when different groups need different restrictions. If targeting is weak, admins end up using overly broad rules that undermine lockdown goals.
How to check
Request a demo where two groups get different rules (for example, admin versus learner) on the same endpoint class. Verify you can target by user and by device state, and confirm how profiles are assigned during session start.
Audit logging for policy decisions
Why it matters
Audit logging for policy decisions is how you prove what happened when something fails. Without clear event records, you cannot troubleshoot bypass attempts or validate compliance.
How to check
Ask the admin to run a blocked attempt and then show the resulting audit events. Confirm the log includes enough context to identify the user, the policy, the attempted destination/action, and the enforcement outcome.
Browser version resilience and compatibility
Why it matters
Browser version resilience and compatibility reduce lockdown breakage as browsers auto-update. If enforcement relies on fragile UI assumptions, restrictions can silently fail after upgrades.
How to check
Ask how the product tracks browser changes and what compatibility matrix or guidance it provides. In the demo, question what happens after a browser update: how policies are validated, and whether there is a tested version list.
Red flags
- Users can bypass rules with alternative navigation or window behavior
- Allowlist updates are slow, manual, or lack rollback
- Audit logs do not show policy outcomes clearly
Fit by situation
- If you need quick URL changes during an active program, prioritize Allowlist management and update workflow.
- If you run different restrictions for different groups on the same device class, prioritize Policy scope for users, devices, and profiles.
- If you must investigate blocked attempts after the fact, prioritize Audit logging for policy decisions.
