More than ever before, who a security dealer chooses to work with to get their products — whether a manufacturer or distributor — mattered in 2021. With supply chain shortages cited more than any other factor in how their company performed, SDM 100 companies relied heavily on trusted providers to keep their projects flowing as smoothly as possible, given the challenges. SDM 100 companies operate in a wide variety of geographical and vertical markets, including both residential and commercial business, and educational, government, commercial and institutional customers. These 100 largest U.S.-based security companies are ranked by their recurring monthly revenue (RMR) on the annual SDM 100 Report.

SDM asked each of the 2022 SDM 100 companies to share their top three manufacturers and top three distributors, based on volume purchased. The resulting lists below represents the largest portion of the vendors security companies in the installation and monitoring channel rely on a wide variety of suppliers.

These brand-usage lists were compiled from the 2022 SDM 100 Report. Out of the 100 companies ranked, 80 of them listed their manufacturing partners and 75 shared their distributor partners.
