The complete framework for managing disruptive events

For private organizations

Disruptive events such as health hazards, extreme weather, or even supply chain disturbances can impact business continuity. The Intersec solution allows crisis management teams to keep control and monitor recovery progress in real-time, ensuring response plans get appropriately executed.

Dedicated users can monitor recovery progress in real time thanks to customized dashboards and alert messages, allowing for flexibility to adapt to any scenario and ensure plans get executed properly (the use of emergency text message system for instance).

Anticipate sooner

Gain real-time situational awareness with advanced threat detection and risk intelligence to identify potential hazards before they become crises. Monitor diverse risks such as severe weather, workplace incidents, cyber threats, or IT disruptions, and assess their potential impact on your people, operations, and assets.

With early detection, communication teams can choose the most effective alert channels and prepare response plans that keep employees informed and operations stable from the very first signs of trouble.

Act faster

When every second counts, the ability to communicate clearly and across multiple channels is critical. Intersec supports multichannel alerting via SMS, mobile app notifications, and email, ensuring messages reach the right people through the right channel at the right time.

Alerts can be created in seconds thanks to guided templates and customizable options, reducing delays and removing guesswork. Whether it is an urgent safety threat or a major IT outage, this flexibility enables rapid, targeted communication that protects people and minimizes business disruption.

Improve every response

After a critical event, understanding what worked and where improvements are needed is key to strengthening resilience. Post-incident analytics and performance dashboards transform raw event data into actionable insights, helping you evaluate response times, message reach, and team coordination.

By learning from each incident, mission-critical organizations can refine their plans, close communication gaps, and become more agile in the face of future disruptions.

Frequently asked questions

What is Critical Event Management (CEM)?

Critical Event Management (CEM) is the coordinated process of preparing for, identifying, managing, and resolving events that can disrupt an organization’s people, operations, or reputation. It brings together real-time threat detection, risk assessment, incident coordination, and targeted communications to ensure teams can act fast and make informed decisions.

From extreme weather and natural disasters to cyber incidents, workplace threats, IT disruptions, supply chain failures, and other unexpected crises, CEM enables organizations to stay ahead of both physical and digital risks. By connecting the right information with the right people at the right moment, it helps safeguard employees, reduce operational downtime, and build long-term resilience.

What is a mass notification system for organizations?

A mass notification system is a communication solution that allows organizations to send urgent or important messages to large groups of people instantly. It delivers alerts via multiple channels such as SMS, email, voice calls, desktop pop-ups, and mobile push notifications to ensure messages reach everyone, no matter where they are.

What types of messages can be sent?

Organizations can send critical alerts, safety instructions, IT outage notifications, weather warnings, event updates, or operational announcements. The system supports both emergency use and day-to-day internal communications.

Why do organizations need a mass notification system?

Fast, reliable communication helps protect employees, maintain business continuity, and reduce downtime. In emergencies, it can save lives by ensuring everyone receives the right information at the right time, through the channels they use most.

By enabling instant communication during crises—such as cyber incidents, natural disasters, or supply chain disruptions—organizations can respond faster, minimize disruption, and keep critical operations running.

What types of events require mass notifications?

These include severe weather events, IT outages, workplace safety threats, public health incidents, transportation disruptions, and any situation that impacts employee safety or operational performance.

Messages are typically sent and received within seconds, even to large, distributed teams. The system is designed to perform under high load and during network congestion.
