The cybersecurity sector in Hauts-de-France includes a mix of large groups and mid-sized firms, predominantly in IT services and software development. Companies like IDEMIA provide global payment, connectivity, cybersecurity, and biometric solutions, while Hornetsecurity France offers cloud-based security and compliance. Nordnet specializes in internet access and digital identity services, and Oneytrust focuses on online fraud prevention for e-commerce and finance.
Most of these companies are headquartered within the Hauts-de-France region, with notable clusters in cities such as Villeneuve-d'Ascq and Lille. While some, like group-solutions, were founded in the 1980s, there is also a presence of younger companies such as Wakers, founded in 2020, specializing in cloud security.

Turn this list into pipeline
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 13, 2026.
