What is SD-WAN in plain terms?
Software that manages multiple internet connections as one intelligent network. Instead of traffic taking whatever path it happens to get, it is routed along the best available one based on what the traffic is - a video call and a backup job have very different needs and stop competing for the same pipe.
Do we need it if we only have one office?
Possibly, for a different reason than multi-site businesses. With one location, the case for SD-WAN is redundancy: a second connection means an outage on the primary circuit does not stop your business. If your phones, line-of-business apps, and files are all cloud-based, that single circuit is now a single point of failure.
Can we drop our MPLS circuit?
Often yes, and that is where the cost savings usually come from. SD-WAN combines MPLS, broadband, Starlink, and 4G/5G into redundant paths, so expensive private circuits can frequently be reduced or retired in favor of cheaper connections that are made reliable through redundancy rather than through price.
How does this help with security?
Security is built into the network rather than bolted on at the edge. Zero Trust controls, next-generation firewalling, and real-time threat protection travel with the connection, so a remote office or a home worker gets the same enforcement as someone sitting in the main office. That consistency is usually what is missing.
What happens when one connection fails?
Traffic moves to a working path automatically, and the intent is that active calls and sessions stay up rather than dropping and needing to be restarted. How seamless that is depends on your connection mix, which gets designed deliberately rather than left to chance - so it is worth being specific about which systems absolutely cannot blink.
