A network problem doesn't always begin with a complete outage. It may start with increasing latency, packet loss on an ISP link, an unstable VPN tunnel, or slow performance for a cloud application. SD-WAN may automatically move traffic to another available path, allowing users to continue working. But there is still a problem. Something has changed—and the IT team needs to know why. This is where the combination of Managed SD-WAN and 24×7 NOC monitoring becomes valuable.
