SD-WAN, MPLS or VPN?
| Feature | SD-WAN | MPLS | Site to site VPN |
|---|---|---|---|
| How sites connect | Any internet connections, managed as one network | A private network from one carrier | Encrypted tunnels between firewalls |
| Failover | Automatic, across two or more connections | Depends on a backup circuit | Manual or basic |
| Adding a site | Fast, with any local internet | Slower, the carrier must reach it | Fast, but each tunnel is managed by hand |
| App performance | Sends each app over the best path | Consistent on the private network | No app awareness |
| Visibility | One dashboard for every site | Carrier reports | Site by site |
| Typical cost | Moderate | Highest per site | Lowest |
Signs you are ready for SD-WAN
- Calls or video drop when one site’s internet gets busy.
- A single internet outage stops a location.
- Branches use different equipment and nobody can see the whole network.
- Your MPLS contract is up for renewal.
- You are adding locations faster than your network can keep up.
- Your cyber insurance application asks how branches are protected.
What to have ready for a quote
- A list of locations with addresses and the number of people at each.
- Current internet or MPLS service at each site, with contract end dates.
- Your firewalls and who manages them.
- The apps that matter most, such as phones, point of sale and cloud servers.
- Compliance needs such as HIPAA or PCI.
Start with your contracts. The best time to move to SD-WAN is as your current network contracts end, so we map every end date first and plan the rollout around them.
