PSI Secure Browser vs Safe Exam Browser

PSI Secure Browser provides a locked-down environment for online exams, supporting the process from launch and identity authentication through proctor connection, testing, and session end. Check-in may include a photo ID, selfie, room and floor-to-ceiling scans, accessory scan, and desk scan. PSI says the browser restricts other websites and applications and blocks actions such as copying, pasting, printing, and screen capture. It is offered as a downloaded browser or as a separate Chrome Extension. The Secure Browser supports specified 64-bit Windows 10 and 11, macOS Sonoma, Sequoia, and Tahoe, and Ubuntu 22.04, 24.04, and 26.04 LTS. Chromebooks cannot run the Secure Browser, though they can use the extension. Installation and administrator access are required on the test computer. Proctored exams require a webcam and microphone, and the camera must stay on during the exam. PSI offers live and record-and-review proctoring. Pricing is available on request.

Safe Exam Browser (SEB) is a browser environment for e-assessments that restricts a device to exam use. It runs locally and connects over the internet or a LAN to a learning management system or web-based exam system. Listed compatible systems include Moodle, ILIAS, OpenOlat, Open edX, Canvas, and Inspera Assessment. SEB supports encrypted exam configurations, URL filtering, restricted browser windows, and detection of virtual machines or jailbroken devices.

Controls vary by platform. On Windows, process monitoring can hide or terminate disallowed programs, while administrators can permit selected third-party applications. On iOS, Assessment Mode blocks app switching, unauthorized websites, notifications, calls, and screenshots; activation requires a SEB Quit Password. SEB has no central server or cloud service, though an optional open-source server can be self-hosted. Optional audio or video proctoring is disabled by default and requires candidate consent when configured. SEB is freeware for Windows, macOS, and iOS. The security module for application integrity verification is distributed only as a binary, not as open source.
