Everbridge, Inc. [EVBG] last Thursday said it has acquired the cyber security firm NC4, allowing it to create an end-to-end platform for critical event management and cyber threat assessment.

Everbridge said it paid $83 million for NC4 in cash and stock. Everbridge said parts of the deal have closed and the rest will be completed during the third quarter. With the acquisition, Everbridge has more than 950 employees.

Everbridge, based in Massachusetts, provides critical communications and enterprise safety applications through a software-as-a-service platform to construct and deliver contextual mass notifications during public safety, terrorist threats and critical business events.

NC4, based in California, provides around-the-clock threat intelligence and analysis for companies and the government. Everbridge said that NC4 generates more than 27,000 geo-targeted alerts and nearly 700 incident reports daily for its customers.

Everbridge said the acquisition brings together its Global Intelligence Operations Center analysts with NC4s threat intelligence and analyst teams.

“With NC4, we are adding the industry leader in threat intelligence, making Everbridge one of the largest providers of data for enterprise security and operations in the world,” David Meredith, CEO of Everbridge, said in a statement. “NC4 offers the most comprehensive threat data in the world and this acquisition dramatically expands the overall situational awareness Everbridge will provide organizations, from incident identification to response, mitigation or ultimately, avoidance and prevention.”
