# ExpressRoute circuit

An ExpressRoute circuit is a dedicated private connection between your on‑premises network and Microsoft Azure. It bypasses the public internet to provide more reliable performance, higher security, and consistent latency for workloads that need stable connectivity. It supports multiple bandwidth options and can connect to many Azure services through a single circuit.
