About Cyso
Cyso has been delivering managed internet services, platforms, and infrastructure from its own Dutch data centres since 1997. Its flagship Cyso Cloud is a private VMware-based platform spread across two geographically separated, dark-fibre-connected data centres in the Netherlands, providing high availability without public-cloud IO limits.
The company pairs its infrastructure with professional services — DevOps on Demand, Mission Control, SRE, and Cloud Operations — so customers can fully outsource platform management.
Cyber security offerings include managed firewall, SIEM, WAF, and network security. Cyso is ISO/IEC 27001 and NEN 7510 certified, and all data is stored and managed entirely within the Netherlands, ensuring GDPR compliance.
As a 100% independent, Dutch-owned provider, Cyso is a strong choice for organisations that require data sovereignty without dependence on hyperscalers.
