School & Classroom Device Security Software

What is school device security?

School device security is the practice of keeping shared and student-issued computers safe, focused, and consistent across a whole campus. In a lab or a 1:1 program, dozens of students touch the same machines every week, so the challenge is not just stopping malware - it is stopping distraction, off-task browsing, unauthorized software, and the slow configuration drift that turns a clean lab into a support headache by mid-semester.

CtrlOne addresses this with a lightweight agent that runs as a protected system service on every Windows 10 and Windows 11 device and reports to a web console at ctrlone.online. From that console, IT staff push policies to an entire lab, grade level, or campus at once: content-filter categories that block adult, gambling, drugs, piracy, social, streaming, and gaming sites; SafeSearch and DNS filtering; browser lockdown that removes Incognito, extensions, developer tools, and downloads; and application blocks that stop games and installers by name or signature.

Because the agent enforces policy even when a device leaves the network and applies offline fail-closed protection after a window you configure, a student laptop stays locked down at home just as it is in the building. When a shared PC does get messed up, the restore module captures a known-good baseline and returns the machine to that clean state in one click - no re-imaging cart, no reinstall from a USB stick, no lost class time.

Why schools choose CtrlOne

• Keep students on task - Block games, streaming, social media, and unapproved apps so lab and classroom time stays focused on the lesson rather than distractions.
• Safer browsing by default - Category-based content filtering, enforced SafeSearch, DNS filtering, and allow/blocklists give age-appropriate web access on every managed device.
• One-click reset for shared PCs - Capture a clean baseline once, then restore any shared machine to that exact state in seconds instead of pulling it for a full re-image.
• Class and exam scheduling - The auto-scheduler applies tighter restrictions during class periods or testing windows and relaxes them afterward, with no manual toggling.
• Campus-wide consistency - Push one policy to a lab, a grade, or the whole district from a single console so every device enforces the same rules.
• Tamper-proof enforcement - The agent blocks documented uninstall and disable vectors, so curious students can't turn protection off or roll back the lockdown.

Classroom security features

• Content filter categories - Block adult, gambling, drugs, piracy, social, streaming, and gaming categories, and layer on custom allow/blocklists per school or lab.
• Browser lockdown & SafeSearch - Force SafeSearch and DNS filtering, set a fixed homepage, and remove Incognito, extensions, developer tools, and browser downloads.
• Kiosk mode - Lock a shared PC to a single approved app or site for testing stations, library catalogs, and check-in terminals.
• Block games & unauthorized apps - Stop games, installers, and off-task software by name or signature using AppLocker deny, SRP, IFEO, and DisallowRun.
• USB storage lockdown - Set USB mass storage to off, read-only, or block while keeping keyboards, mice, and printers working for normal classroom use.
• Auto-scheduler for class windows - Apply and remove restrictions automatically on a daily time window so exam and class-period rules turn on and off on their own.
• Restore module - Capture a clean, approved baseline and return shared machines to it with one click, undoing whatever a prior student changed.
• Lab / Classroom template - Start from the built-in Lab-Classroom policy template, then tailor it to each room and roll it out across the fleet in one click.

Where schools deploy CtrlOne

• Computer labs - Standardize every machine in a shared lab with the same filtering, app blocks, and one-click restore between classes.
• 1:1 student laptops - Keep take-home devices filtered and locked down off-network with offline fail-closed enforcement.
• Exam & testing centers - Use kiosk mode and scheduled lockdowns to hold devices to a single approved app during assessments.
• Library & front-desk PCs - Lock public and check-in terminals to approved sites and reset them to a clean state on demand.
• District IT teams - Manage labs and student devices across many schools from one multi-tenant console with per-site branding.
