OverlaySense

An overlay visibility and telemetry platform for software-defined wide-area networks (SD-WAN) provides extensive, vendor-agnostic insights into network performance, health, and routing by aggregating and normalizing telemetry data from branch appliances, controllers, and overlay tunnels in real-time. Its main features include automated appliance discovery, high-fidelity telemetry streaming, multi-controller analytics, overlay path correlation, historical trend analysis, role-specific dashboards, and open APIs, all designed to improve operational decision-making, troubleshoot quickly, and ensure compliance across large, distributed enterprise or service provider networks. This system addresses challenges such as fragmented management, slow fault detection, vendor silos, and complex troubleshooting for network operations teams, network architects, and security professionals managing extensive SD-WAN deployments.

OverlaySense can be found in Application Monitoring & Observability categories.
