Alert 360

Alert 360 was founded in 1973 as Guardian Security Systems in Oklahoma City — making it one of the oldest licensed alarm monitoring providers in the United States, with a continuous operating history that spans more than five decades of American residential and commercial security market evolution. Now headquartered in Tulsa and operating 32 locations serving customers in 26 states, Alert 360 has grown from that small Oklahoma installation and monitoring business into the fourth-largest residential security company in the United States — a nationally significant security organization that maintains its Oklahoma roots while serving hundreds of thousands of customers coast to coast. The company has operated under several identities across its 52-year history, including Guardian Security Systems and Central Security Group, before settling on Alert 360 in 2018.

Alert 360's operational foundation is its TMA Five Diamond designated alarm monitoring and customer service center in Tulsa — a certification awarded to fewer than 5% of alarm monitoring centers nationally, recognizing the highest standards for operator training, monitoring protocols, and emergency response procedures.
