These Swiss companies specialize in cybersecurity and related IT services, with a notable presence of large and mid-sized firms. Companies like SGS offer testing, inspection, and certification services, while Bechtle Schweiz AG provides comprehensive IT consulting and infrastructure solutions. Kaspersky focuses on global cybersecurity, and Kudelski Group integrates content protection with cybersecurity. ELCA Group delivers IT services and solutions, including cybersecurity and cloud, and Acronis offers cyber protection with antivirus and backup.
A common pattern is the focus on IT services and cybersecurity, with a mix of established players and younger companies. For example, Proton, founded in 2014, specializes in privacy-focused communication tools, and Sonar, founded in 2008, develops tools for code quality. Many of these firms serve a broad international clientele.

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 12, 2026.
