Secior is a Dutch cybersecurity company that helps organizations become structurally more digitally resilient. We offer high-quality services and training aimed at board, management and operational teams within critical sectors such as government, healthcare, transportation and data centers.
Our expertise lies at the intersection of laws and regulations, technology and behavior. With programs such as the NIS2 Governance and Management Training, the Interactive Compliance Workshop, Continuous Actual Cyber Resilience and the Trivian Cybersecurity Training, we support organizations in demonstrably complying with legislation as well as increasing their actual cyber resilience.
Secior stands for a pragmatic approach, in-depth content and committed cooperation. We believe that true security starts with awareness, ownership and practical applicability.
Our origins are in the data center industry, where we have built a solid reputation for designing, building and operating environments with the highest availability and security requirements. After selling our data center business to Eurofiber, we chose a new direction. We invested in research, strengthened our team with specialists in OT, IT and IoT cybersecurity, and in 2020 launched a revamped organization called Secior - with the mission of making organizations not only compliant, but above all cyber resilient.
