WE ARE A TEAM OF CYBERSECURITY INDUSTRY VETERANS FOCUSED ON SECURING THE WORLD’S COMMUNICATION INFRASTRUCTURE. 

OUR MISSION

Targeted attacks on cloud communication platforms like email and chat tools are the biggest threats facing the modern connected enterprise. The impact of these cyberattacks is tremendous — over $400m in damages as of the most recent FBI studies.

In the face of this enormous problem, we believe that effectively securing the channels through which organizations collaborate and communicate is essential, and we believe that intelligent data can help companies do so securely and efficiently.

GreatHorn is the world’s first cloud-native communication security platform, combining machine learning-driven threat detection and automated response capabilities to enable our customers to identify and shut down targeted cyberattacks before damage occurs. Our products enable organizations to embrace new cloud-connected communication technologies while protecting data, financial resources, and intellectual property from advanced targeted threats.
