Securing what matters most since 1930
Guardian Alarm’s company headquarters is located in Southfield, Michigan after moving there from Detroit in the 1980s. We’ve stayed close to our roots since the company was established in 1930.
As one of the largest, independently-owned security companies today, we’ve got years of experience helping to monitor and protect families, employees and the communities in which they live and work. From single family homes to multiple corporate locations, all the way to corporate high-rise office buildings, we’ve been in the business from the beginning.
Trust the security of your family and home to a local business that really knows security.
