# AlertIO

> AlertIO is a multi-tenant SaaS platform that delivers full-screen emergency alerts to every device on a K-12 school campus — Chromebooks, Windows PCs, Macs, Linux workstations, Raspberry Pi / DAKboard digital signage, and Android tablets — in seconds. It's purpose-built to replace or augment legacy intercom and PA systems for lockdowns, evacuations, shelter-in-place, severe weather, and drills.

AlertIO is operated by GDA Technology and is sold as a subscription with three plans (Small Campus, Large Campus, District Wide). Schools install lightweight native agents (Windows, macOS, Linux, DAKboard OS, Android) or a Chrome extension on every device; the agents maintain persistent WebSocket connections and display a full-screen, high-contrast alert overlay the moment one is triggered. Alerts can be triggered from the dashboard, from any system that can hit a secure webhook URL, or from a third-party panic button / SIS / RMM integration.
