SD-WAN

Keep Microsoft 365, VoIP, and cloud apps working when an internet link fails

ITried designs SD-WAN and multi-link failover for businesses that need stable calling, cloud access, branch connectivity, and clear visibility into network performance.

Quick answer

When should a business use SD-WAN?

Use SD-WAN when downtime affects calls, Microsoft 365, payment systems, VPNs, branches, or cloud applications. SD-WAN can monitor multiple links, steer traffic to the best path, fail over automatically, and keep network behavior visible.
