OUR MISSION IS PERSONAL. We are committed to providing customizable, scalable, and cost-effective mass notification solutions because we know even a few seconds of warning can help save lives during an emergency.

An idea was born to engineer a mass notification solution that can be implemented anywhere and activated quickly to help prevent another tragedy. Alertus was founded in 2002 and has focused its efforts on developing superior lifesaving notification solutions ever since. Alertus' dedicated teams of safety, security, and technology leaders are committed to continuously raising the bar for mass notification.

At General Dynamics Mission Systems, a business unit of General Dynamics, we develop mission critical C4ISR solutions across the land, sea, air, space and cyber domains, but that doesn’t tell our whole story. When downed pilots are isolated in enemy territory, our equipment gives them a lifeline to call home. When a student opens a textbook to learn about the universe, they’re looking at data and pictures sent using our technology. When the government needs to share crucial top-secret information, our products help them keep this information out of the wrong hands. When sailors need to locate underwater mines, our technology allows them to find explosives with unmanned underwater vehicles. Delivering C4ISR technology is what we do but we think why we do it is more important.
