Cyso Reviews

Founded in 1997, Cyso is a Dutch managed hosting provider specializing in complex, business-critical internet services, platforms, and infrastructure. Headquartered in Alkmaar, Netherlands, Cyso positions itself as one of the oldest independent hosting providers in the country. With over 25 years of experience, the company serves a diverse client base, including large businesses, corporations, financial institutions, IT professionals, government agencies, and software vendors, both domestically and internationally. Cyso emphasizes customized, tailor-made solutions rather than a one-size-fits-all approach, focusing on quality, service, and technical expertise. Their infrastructure includes their own network and geographically separated data centers located entirely within the Netherlands, ensuring compliance with Dutch and European regulations like GDPR. They operate cloud platforms based on VMware and OpenStack (Cyso Cloud, which integrated Fuga Cloud in 2025), offering high-performance, secure, and scalable solutions free from vendor lock-in. Key services include managed hosting, cloud infrastructure (including Cyso Cloud and managed Kubernetes), cybersecurity services (like SIEM, WAF, managed firewalls), and professional DevOps support. Their target audience consists mainly of businesses needing reliable, secure, and managed environments for complex applications and platforms, often requiring high uptime (SLAs up to 99.9% for 'Mission Critical' plans) and robust security measures. Cyso is part of the Cyso Group, which also includes Hosting.nl.
