# List of cybersecurity companies in Italy

Tamtam tracks 73 cybersecurity companies headquartered in Italy. This list ranks the 50 largest by number of employees on LinkedIn, led by Leonardo, TIM and Reply. Their median headcount is 508. Half of them were founded in 1996 or later. The most common headquarters are Milan (17), Rome (12) and Turin (5).

These Italian companies specialize in cybersecurity, with a strong presence in IT services, telecommunications, and defense. The list includes large established groups such as Leonardo, a multinational in aerospace, cybersecurity, and military systems, and TIM, which provides fixed, mobile, and digital services. Mid-sized firms like Reply deliver consulting and digital services using AI and big data, while Engineering Group focuses on digital transformation and proprietary solutions.

A notable pattern is the concentration of headquarters in major cities. Rome hosts several key players, including Engineering Group and DGS, which offers security and digital transformation services. Milan is another significant hub, with companies like Lutech, an innovation company providing end-to-end digital transformation solutions, and BV TECH, specializing in technology, security, and innovation.

## 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 12, 2026.
