In 2025, the topic of information security is no longer an option for Italian companies. Regulatory pressure (GDPR, NIS2, DORA, PSD2), combined with the escalation of advanced cyber attacks — such as ransomware-as-a-service and AI-driven threats — compels businesses to ensure a structured system for data protection. This is where ISO 27001 certification comes into play, the global benchmark for Information Security Management Systems (ISMS).

In this article, you will discover the 10 best companies in Italy for ISO 27001 compliance in 2025, with a clear assessment of their strengths and ideal targets.
