# The 50 largest Security Systems Services companies in Europe

Tamtam tracks 71 Security Systems Services companies headquartered in Europe. This list ranks the 50 largest by number of employees on LinkedIn, led by DEF, ERYMA SECURITY SYSTEMS and Argenbright Security Europe Limited - ASEL. Their median headcount is 60. Half of them were founded in 1994 or later. The most common headquarters are Ivry-sur-Seine (2), London (2) and Massy (2).

These companies specialize in security systems and services across Europe, encompassing a range of activities from fire safety and cybersecurity to physical surveillance and electronic security solutions. The firms listed are primarily mid-sized to large, with several established entities alongside some newer ones. For instance, DEF provides fire safety systems, ERYMA SECURITY SYSTEMS focuses on custom cybersecurity, and Argenbright Security Europe Limited offers technology-driven risk management. Schrack Seconet AG specializes in fire alarm and healthcare systems, while ANAVEO GROUPE offers intelligent security systems.

A notable pattern among these companies is their diverse geographical spread across Europe, with concentrations in countries like France, the UK, Austria, and Italy. Many companies, such as Banham Group (founded 1926) and DEF (founded 1958), have a long history, indicating a mature market for security services.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 14, 2026.
