Lockdown Browser & Browser Security

A lockdown browser establishes a controlled digital environment built specifically for maintaining online exam security. On an ordinary computer, a second browser window, a messaging app, or an AI search tool is only a click away. By blocking these digital routes, including advanced bypass methods like virtual machines, remote desktop software, and unapproved screen sharing, browser restrictions sharply reduce the opportunity for digital cheating and ensure a uniform, secure testing environment for everyone.

However, traditional lockdown browsers require candidates to download, install, and configure heavy, standalone software applications that take complete control of their operating system. These legacy programs frequently trigger firewall blocks, cause device-level operating system crashes, and create high technical friction for candidates right before a high-stakes test.

The Proctor360 Approach: Rather than forcing users to download a separate, cumbersome application, Proctor360 delivers robust lockdown restrictions through a lightweight, secure Browser Extension. This cloud-first architecture enforces identical security protocols, completely blocking new tabs, copy/paste functions, print commands, screenshots, and dual-monitor usage, directly within the candidate's existing browser interface.

It is important to remember what browser security controls cannot do on their own. While they tightly secure the digital interface, they cannot see beyond the machine to detect a smartphone, physical notes, or an unapproved person in the room. For this reason, Proctor360 pairs our secure extension architecture with advanced webcam proctoring, identity verification, and multi-angle hardware. The browser security contains the screen, while our proctoring ecosystem guards the physical room, forming a comprehensive defense for high-stakes online assessments.
