Our verdict on Open Systems SD-WAN

Open Systems SD-WAN is a cloud-deployed enterprise networking service from Open Systems AG. It connects branches, private networks, cloud environments, and mobile users across internet, MPLS, and other transports through an encrypted overlay. The service is aimed at globally distributed organizations that need application-aware connectivity, managed network and security operations, and a private global backbone rather than a standalone configuration tool. Web and API access are supported, and the service operates through Open Systems’ SASE platform.

Pricing is handled through sales, so buyers should approach it as a managed-connectivity engagement rather than a packaged subscription with clearly separated public tiers. The published offering combines network and security capabilities, including automatic encryption and authentication between sites, application-aware policy routing, bandwidth control by application, location, and connection, and integrated policy-driven firewalling. Its cloud deployment model and cloud-onramp support fit organizations linking branches with cloud environments and private networks. The managed structure can also suit teams that want network and security operations included alongside the connectivity layer.

The standout strength is the breadth of application control. Open Systems SD-WAN can select paths by application, define fallback ordering for degraded or failed links, expose resource-consumption and trend data, and apply caching, compression, and protocol optimization. That combination is useful when performance and continuity need to be managed at the application level, not only at the circuit level. Buyers wanting a private backbone and operational support should shortlist it; teams seeking transparent tiered pricing, a lightweight self-service deployment, or a narrowly scoped branch networking product should compare other options before choosing.
