For the exams that cannot leak.
Certifications, final rounds, regulated roles — some sittings need more than monitoring. 5Profiler’s lockdown tier runs a certified secure exam browser: OS-level control with cryptographically verified configuration, managed from the same campaign screen as everything else.

Six layers against AI assistance
Nobody can honestly promise “AI-proof.” We promise layers: machine control, a side-view camera on the desk, per-candidate adaptive forms, server-anchored timing, telemetry — and humans reviewing what the layers surface.
- OS-level control — the certified lockdown tier blocks the escape routes screen-sharing tools use.
- Config that can’t drift — per-candidate configuration verified cryptographically before entry.
- BYO or managed lab — run on candidate machines or your assessment-centre fleet — both flows supported.
- Fail-closed option — campaigns can refuse entry entirely when verification fails — your call, per campaign.
From invite to verified sitting
1 · Distribute
Candidates get the installer and a per-candidate configuration — versions checked, entry approved.
2 · Verify
The exam only opens when the exact configuration matches — tampered setups never reach question one.
3 · Contain
Apps, clipboard, screen capture and virtual machines blocked at OS level for the duration.
4 · Layer
Combine with dual-camera side view and live monitoring for certification-grade sittings.
The final round that stayed final
A certification-grade final round ran on lockdown: installers version-checked, configurations verified at entry, side-view cameras on, live console watching 41 sessions. Two tampered setups never got past the door — and the 39 legitimate candidates sat an exam whose results nobody could dispute.
Questions we always get
Do all our tests need this?
Almost certainly not — lockdown is the top tier of four, for the sittings where stakes justify the friction. Most campaigns run lighter tiers.
What do candidates install?
A certified secure-exam-browser package plus a per-candidate configuration file; versions are checked and entry is approved before the sitting starts.
What about accessibility?
Accommodations still apply — the tier adjusts rather than excludes, and exemption policies are configured per campaign.
