On1Call

On1Call is a Swedish IT company based in the Stockholm area, providing businesses with IT infrastructure, connectivity, data storage and specialist support. As both an IT provider and internet operator, it manages communication from the internet and its own data centers to customers’ offices, reducing reliance on other individual operators. The company’s cloud services and data storage are designed to keep information within Sweden and operate under Swedish jurisdiction, supporting organisations with sensitive data and compliance needs.

On1Call offers cloud, internet, data center, network, consulting and broader IT services, along with secure calling, remote support and operational information. Its data centers in the Stockholm region are described as having redundant power, ventilation and internet access, physically separate backup, and around-the-clock security staff. The company says it has spent more than a decade developing robust infrastructure used by private organisations, Swedish regions and municipalities, including systems subject to requirements such as the NIS Directive.
