Best Cybersecurity Companies in Croatia (Updated 2026)

Croatia’s cybersecurity market has grown significantly over the past five years. Driven by EU NIS2 compliance requirements, a booming digital economy, and strong technical talent from universities in Zagreb, Split, and Rijeka, the country now supports several world-class security firms that compete on the international stage.

Whether you are a Croatian enterprise seeking local expertise and language support, or an international company looking for a cost-effective European security partner, this guide covers the top firms operating out of Croatia in 2026.

Why Croatia for Cybersecurity?

Croatia joined the EU in 2013 and is fully subject to GDPR, NIS2, and the EU Cybersecurity Act — meaning local providers are well-versed in European regulatory requirements. The country also benefits from:

Strong technical universities — University of Zagreb’s Faculty of Electrical Engineering and Computing (FER) produces well-trained security engineers
Competitive pricing — significantly lower day rates than Western Europe with no compromise on quality
EU data residency — work stays within EU jurisdiction, critical for regulated industries
Growing startup and fintech ecosystem — local security firms have sharpened their skills on demanding clients

How to Choose the Right Croatian Security Partner

When evaluating Croatian cybersecurity firms, consider these factors:

Scope of engagement — Infigo IS and Diverto for one-time offensive testing; Span and KING ICT for ongoing managed services; Trikoder for application security
Industry expertise — ask specifically about clients in your sector (banking, healthcare, energy) and relevant certifications
Certifications — look for OSCP, CEH, CISA, ISO 27001 Lead Auditor credentials on the team
Language and reporting — most Croatian firms produce reports in both Croatian and English
NIS2 readiness — if you are a regulated entity, confirm the firm has helped clients through NIS2 compliance assessments
