We were lucky enough to partner with Defend Systems for this training, and if anybody asks me if this was a worthwhile investment in not just the training, but in protecting your students on campus, absolutely, period, stop!” - David Skeen, Head of School, Harding Academy, Nashville, TN

We are grateful for the work of Brink Fidler and Defend Systems. They assessed our existing emergency plan and gave us thoughtful recommendations for security upgrades. ”

Defend Systems has been invaluable to our organization. They helped us identify security issues and consulted with us on how to create and implement (if ever necessary) an emergency plan that keeps everyone as safe as possible. When we began planning our move to our current facility, they helped us by identifying areas that needed to be more secure and suggested ways to make it happen. They not only consulted with us, but also provided training for staff members.
