About Security 50

Every year, the a&s editorial team collects financial data from major security manufacturers/suppliers to determine the annual winners for the ranking of the top 50 companies, which either have the largest market share in the global market or the highest product shipment to its global partners. The first a&s Security 50 was announced in 2003. a&s Security 50 demonstrates how the security industry have proceeded through different product life cycle stages, as well as the ups and downs of the security industry over the past 14 years. The annual Security 50 reports also give a comprehensive overview of the physical security industry.


About the Security 50 Ranking:

a&s ranked global public-listed manufacturers solely by product sales revenue, gross profit, and profit margin, which were listed in their public financial reports for the 2016 fiscal year. Participants range from exclusive manufacturers to end-to-end solution providers. Again, we urge readers not to focus on the ranking of the participants, but to further explore the underlying causes for their success.
