A Company That Deters, Disrupts, and Delays™ Active Assailants

Crotega was formed as a result of an educator’s vision. The national tragedies of Sandy Hook and other school shootings impelled Jody Allen Crowe to find a solution to active shooter situations. He brought together experts from several fields to research and develop an innovative structural change to buildings that will have a lasting impact on the interior control of buildings.

The concept of a building intruder defensive shield is a first-of-its-kind system for protecting building occupants. SentriZone™ has the potential to change building infrastructures in the same manner fire sprinklers did for fire control.

The SentriZone system dispenses REPULS®, a revolutionary water-based chemical irritant spray, to neutralize active threats. Crotega has pioneered a discreet unmanned remote vehicle, SentriLaunch™, that also deploys the spray.

Crotega has offices and research and manufacturing facilities in Minneapolis, MN.

About The Name

Crotega” combines the first three letters of founder Jody Allen Crowe’s last name with a form of the Latin verb “tegere“, meaning to cover or shield.
