Never before has an elite team of trainers like this been assembled in America.

Our expert trainers know what to do.


Active Threat Solutions is an organization comprised of individuals who have dedicated their lives to making the world a safer place. From corporate offices in New York City to small classrooms in middle America, our team uses the knowledge acquired over their individual careers to educate in a way that is conducive to learning, not frightening. We don’t shoot blanks in your office, we don’t simulate shootings, We teach everyday people to solve problems using their own creative solutions. This instills confidence that cannot be found elsewhere. Combine that with improving environments through our assessments and services, we bring our experience in not only security, but people to you.
