The cybersecurity companies in the Community of Madrid are predominantly large and well-established IT services and consulting firms. Many of these companies, such as Minsait, NTT DATA Europe & Latam, and Indra Group, provide a wide array of services including cloud computing, digital transformation, and defense solutions, often with a global reach. Telefónica Tech also offers a strong focus on cybersecurity, alongside other tech services like IoT and AI. This indicates a mature and broad cybersecurity market.
A notable pattern is the concentration of headquarters in Madrid, with a few in nearby Alcobendas and Tres Cantos. The founding dates, such as GMV (1984), Zelenza (1984), and Sermicro (1985), suggest a strong presence of companies that have evolved with the digital landscape over several decades, rather than a proliferation of recent startups.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
