Everbridge provides a critical event management (CEM) platform that enables organizations to anticipate, mitigate, respond to, and recover from critical events.

The company's High Velocity CEM platform, powered by Purpose-built AI, combines intelligent automation with comprehensive risk data to manage both physical and digital threats. The platform enables organizations to identify threats, determine which assets and people are at risk, and initiate coordinated responses across teams. Core capabilities include mass notification and incident communications that send messages via SMS, email, desktop alerts, and voice channels. Everbridge serves over 6,500 global organizations across enterprise and government sectors. The platform sends 5 billion messages annually to 600 million people and holds over 160 worldwide patents. Organizations use the system to manage various critical events including severe weather, active shooter situations, IT outages, and digital service disruptions.
