# UserAuthGuard

> Zero-trust K-12 Chromebook security software by Asan Digital LLC. Patent-pending OU-Lock technology binds devices to Google Workspace organizational units for infrastructure-level security.

## Product Overview
- [Features](https://userauthguard.com/features/): 1:1 device assignment, OU-Lock, real-time tracking, lost mode, check-in/check-out, bulk assignment, inventory management, compliance reports
- [Pricing](https://userauthguard.com/pricing/): Free (100 devices), Pro ($4.99/student/year), Enterprise ($5.99/student/year)
- [How It Works](https://userauthguard.com/): 3-step zero-trust architecture -- device identity binding, infrastructure-level policy enforcement, automatic compliance

## Key Differentiators
- Patent-pending OU-Lock enforces security at Google Workspace level (not agent-based)
- Complementary to content filters like GoGuardian and Securly (not a replacement)
- Deploys through Google Admin Console force-install — no imaging, no per-device setup
- FERPA and COPPA compliant
- SendGuard: per-student approved email contacts for phone ban compliance

## SendGuard — Email Contact Management
- [SendGuard](https://userauthguard.com/sendguard/): Controlled student-parent email communication via Google Groups
- Solves the #1 concern with school phone bans: students can still reach parents
- Each student gets a school-domain email address (parent-jsmith@school.edu) that reaches approved contacts
- No new apps needed — works with existing school Gmail
- Google Workspace-level enforcement — no extension or agent required
- Prevents unauthorized external email while allowing approved parent communication
