Open Systems

Open Systems is a Swiss company from Zurich that has been running other organisations' networks since 1990 — long before the industry had a name for it. What it sells is not an appliance but an outcome: a managed secure network, delivered and operated by its own engineers from operations centres in Switzerland, the United States and Australia. Its platform combines SD-WAN with security service edge, and the firewalls listed here — its LAN, OT and SD-WAN firewall services — are components of that managed service rather than products bought and configured by the customer. Its market is mid-sized multinationals without large security teams of their own, and its Swiss base is part of the proposition for buyers with data residency concerns. As a managed network service it is not measured by the malware laboratories; what a buyer is assessing is an operations contract.
