Public Warning
Communicate information and alert residents and visitors of imminent and developing emergencies with a unified multi-channel, intelligent population alerting platform.
What is a public warning system?
Everbridge Public Warning is a public warning system that helps governments and emergency authorities send urgent, location-aware alerts to people at risk during imminent or developing emergencies. It combines modern mobile alerting with traditional communication channels so residents, visitors, and responders can receive clear instructions quickly and at scale.
- Serves residents and visitors: Reach people in affected areas, including citizens, tourists, commuters, and other transient populations.
- Uses multiple alerting channels: Send warnings through cell broadcast, location-based SMS, address-based SMS, and legacy media such as TV, radio, sirens, email, voice calls, and social media.
- Improves speed and coverage: Deliver time-critical messages to millions of people in seconds across targeted geographic areas.
- Supports compliance: Help public authorities meet population alerting requirements, data protection expectations, and public safety mandates.

Public Warning FAQs
A public warning system helps governments and emergency management organizations rapidly notify people during emergencies such as severe weather, natural disasters, public safety threats, or infrastructure incidents. These systems use mobile networks, location-based technologies, and multi-channel communications to deliver targeted alerts and safety instructions to affected populations in real time.
Public Warning is a unified, multi-channel population alerting platform designed to communicate information and alert residents and visitors during emergencies.
Trusted by national governments in over 25 countries, including the UK, Germany, Australia, New Zealand and Singapore, Public Warning protects more than 800 million people globally.
Public Warning combines cell broadcast, location-based SMS, and address-based SMS with traditional communication channels like email, voice calls, sirens, radio, TV, and social media.
Passive data from mobile networks is used to identify devices in a specific area without tracking or storing individual locations. Public warning deployments can be configured to minimize or avoid the collection of personally identifiable information, depending on deployment model, regulatory requirements, and communication method. Privacy protections, governance controls, and configurable operational policies help organizations balance public safety objectives with privacy and data protection considerations.
Yes, it uses data already stored by mobile operators and ensures no PII is exposed or shared with third parties.
Cell broadcast sends messages to all compatible mobile devices connected to specific cellular towers without requiring phone numbers. Location-based SMS targets devices detected within a geographic area using mobile network data, while address-based SMS sends alerts to predefined contact records associated with known addresses or subscriber databases.
Everbridge supports high-volume public warning capabilities designed to help authorities distribute alerts rapidly across large populations during emergencies. Delivery speed depends on communication method, mobile network infrastructure, geographic scope, and operational conditions, but the platform is designed to support large-scale, time-sensitive emergency communications during critical public safety incidents.
Yes. Public warning technologies such as cell broadcast and certain location-based alerting methods can help authorities reach roaming visitors and tourists connected to local mobile networks without requiring prior opt-in. This capability helps improve public safety communications for transient populations during emergencies and rapidly evolving incidents.
Device-Based Geo-Fencing (DBGF) enables alerts to be delivered to mobile devices based on whether the device itself is located within a defined geographic area. This approach can improve targeting accuracy, reduce over-alerting, and help organizations notify affected populations more precisely during emergencies and public safety incidents.
Everbridge supports configurable governance controls, auditability, security practices, and operational workflows designed to help organizations align with GDPR and EECC Article 110 requirements. Compliance responsibilities may vary by deployment model, national regulations, mobile network integration approach, and organizational governance requirements associated with public warning operations.
Everbridge supports integrations with mobile network operators, public safety systems, GIS platforms, emergency management technologies, and national alerting infrastructures. These integrations help authorities coordinate emergency communications, improve operational interoperability, and support targeted public warning delivery across existing operational and telecommunications environments.
Implementation timelines for national public warning deployments vary based on regulatory requirements, mobile network integrations, geographic scope, infrastructure readiness, and operational complexity. Many deployments involve phased implementation approaches that include integration testing, operational validation, stakeholder coordination, training, and public safety readiness exercises before full-scale deployment.
