Bigleaf SD-WAN vs Open Systems SD-WAN

Bigleaf SD-WAN is a web-based hybrid service for improving internet performance for business-critical cloud applications across business locations. Its Cloud Connect uses dynamic quality-of-service classification to prioritize traffic in real time, while application-aware routing sends voice and video toward circuits with lower latency, jitter, and packet loss. High-throughput tasks use circuits with more available bandwidth. The service measures latency, jitter, packet loss, and capacity 10 times per second in both directions, and can shift traffic between ISP circuits while keeping Bigleaf-issued IP addresses unchanged. A preconfigured router installs outside an existing firewall, supports up to four broadband circuits, and is described as having a 90-second installation. Wired and wireless circuits are supported, including fiber, cable, LEO satellite, and 5G LTE. The dashboard shows cross-site performance, alerts, and insights. Pricing is on request, with monthly billing and 12-, 24-, or 36-month agreements available.

Open Systems SD-WAN is a cloud service for enterprises with global operations that depend on cloud and mobile connectivity. It prioritizes business-critical applications and uses available bandwidth. Application-level policies select network paths, balance traffic, and define fallback order when connections degrade or fail. Administrators can control bandwidth by application, location, and connection. Application Optimization uses caching, compression, and protocol optimization to reduce bandwidth use and improve application performance. Traffic between sites is automatically encrypted and authenticated across public or private networks, including internet and MPLS. A single-pass architecture decrypts and analyzes VPN traffic for per-application visibility and consumption trends. Open Systems describes AI-run automation and Level-3 engineers operating network and security operations. Access is through web and API, with integrated security and cloud on-ramps. Pricing is on request. The service was founded in 1990 and is headquartered in Zürich.
