Our Team


Brink Fidler, Founder and President

Having spent nearly two decades in law enforcement, Brink Fidler respectably served with the Metropolitan Nashville Police Department as well as the 20th Judicial District Drug Task Force in Nashville. In addition to his regular law enforcement duties, he also served as an adjunct firearms and tactics instructor. He has planned and conducted hundreds of high risk, tactical, and covert operations. He has served as an officer, narcotics investigator, patrol sergeant, narcotics sergeant, and retired as the Director of the Drug Task Force in Nashville. During his extensive career, Fidler directed and supervised the most complex investigations. These multifaceted investigations involved hundreds of court ordered wiretaps, thousands of hours of physical and electronic surveillance, and hundreds of search warrants throughout the United States.

These years of experience provided Fidler with a heightened understanding of every conceivable way to penetrate any residence or facility, and in the fastest, most proficient way possible. This knowledge, his commitment to security, and his dedication to protection of property and keeping people safe is why he created Defend Systems.
