Guardian Alarm is a security firm headquartered in Southfield, Michigan, United States.

The organization employs more than 500 personnel across multiple U.S. locations.
Specializing in installation, monitoring, and maintenance, Guardian Alarm delivers security solutions for residential and commercial properties. Its product portfolio includes burglar alarms, round-the-clock monitoring services, indoor and outdoor surveillance cameras, video monitoring, smart home automation, access control systems, as well as fire, water, and carbon monoxide detectors.
History
During the 1920s, Milton Pierce, who later founded Guardian Alarm, created and installed his initial burglar alarm at his father's tailoring business in Detroit. Following this experience and employment with a local alarm company, Pierce acquired Guardian Alarm in 1930—a small enterprise then serving only 60 customers—and quickly established his own business.
In 1970, after acquiring an alarm company that operated a security guard division, Guardian Alarm introduced Guardian Guard Services to clients in Michigan and Ohio. This division provides both unionized and non-union security personnel for facilities and special events such as Super Bowl XL held at Ford Field in Detroit.
Two of Pierce’s sons, Douglas and Richard, launched their own alarm companies—Automatic Alarm and Certified Alarm respectively—before merging them with Guardian Alarm in 1975. Since then, Guardian has grown its clientele substantially through acquisitions of smaller security firms.
The company diversified into cash transportation services in 1980 by founding Guardian Armored Security. This branch developed into Michigan's leading armored car provider with close to 200 employees and annual revenues approaching $10 million.
Guardian Alarm expanded its operations to Florida in 2004 by establishing a branch now known as Guardian Hawk Company.
In 2007, the company divested Guardian Armored Security to Loomis. The transaction included three Michigan branches located in Flint, Grand Rapids, and Highland Park.
As of 2022, ownership of Guardian Alarm is held by Certares LP alongside BlackRock, Inc.
