Built for the Workloads That Run Your Business

ExpressRoute keeps your Azure and Microsoft 365 traffic off the public internet — but ExpressRoute is only as good as the network behind it. Lightstorm delivers ExpressRoute circuits over a private, performance-engineered backbone with the operational consistency, security posture, and contractual model enterprise IT teams demand.

Run Microsoft 365 and Teams over Microsoft peering — eliminate the public-internet jitter that breaks voice and video quality at scale
Extend on-premises Active Directory, Entra ID, and identity workloads to Azure with sub-millisecond private paths
Support regulated workloads with end-to-end encryption and traffic isolation that satisfies audit and other contractual requirements
Migrate VMware estates to Azure VMware Solution (AVS) without re-architecting — Polarin handles the bandwidth-heavy lift-and-shift phase
Operate hybrid Azure Arc and Azure Stack deployments with consistent latency between on-prem and cloud control planes
