Everbridge, Inc. is an American enterprise software company that offers applications which provide information about critical events to help with personal safety and business continuity. Formerly known as 3n Global and the National Notification Network, Everbridge began operations in 2002.[2] In an emergency, Everbridge sends messages via telephone, text message and email,[2] but stop once they know that a person has read a message.[3] An app allows emergency managers to track geotagged tweets that contain specific hashtags and use this information to respond to incidents as they occur.[2]
Their system was used in 2012 to send over 10 million messages to residents during Hurricane Sandy.[2][3]
