About Open Systems
At a glance

Open Systems is a Swiss-based managed security and networking company that delivers Secure Access Service Edge (SASE) solutions to enterprise customers. The company combines network connectivity and security functions into a unified, managed service offering. Their core product portfolio includes SD-WAN as a Service, Security Service Edge (SSE) as a Service, and an integrated SASE Experience platform. These services encompass capabilities such as Zero Trust Network Access (ZTNA), Cloud Proxies, Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), and Secure Email Gateways. Network management is supported through a proprietary Mission Control operations center that provides 24/7 monitoring, alert filtering, and incident management. Open Systems targets mid-to-large enterprises with distributed, global operations — particularly in manufacturing, financial services, and other industries requiring multi-site connectivity and security. Their customer base includes organizations managing dozens to hundreds of locations across multiple countries, often following merger and acquisition activity that introduces network complexity. The company's managed services model positions IT teams to offload operational network and security tasks, with Open Systems handling deployment, monitoring, and ongoing management. Customer case studies highlight migrations from MPLS to SD-WAN, ZTNA-based remote access deployments, and SASE consolidations across global site networks. Open Systems is headquartered in Switzerland and has a North American presence. The company holds ratings on Gartner Peer Insights in both the SD-WAN and SSE market categories, with an average rating of 4.8 and 4.6 respectively as of early 2025.
