SD-WAN: an agile, secure, controllable multi-site network

Your branches, data center and cloud must communicate reliably and securely without blowing the WAN budget. SD-WAN intelligently steers multiple links (fiber, 4G/5G, internet) in software.

What is it?

SD-WAN (Software-Defined WAN) decouples the network from hardware: a software layer picks the best path per application, aggregates heterogeneous access, encrypts traffic and is managed from a central console.

Business benefits

Agility: add a site in days, with no heavy reconfiguration.
Resilience: automatic failover between links on outage or degradation.
Application steering (VoIP, ERP, video) for quality of experience.
Cost: mix internet and 4G/5G where MPLS would be oversized.

Enterprise use cases

A branch network linked to the central data center and cloud with 4G backup.
A company replaces costly MPLS with hybrid SD-WAN.
A sensitive site secures and prioritizes its IP telephony.

FAQ

SD-WAN or MPLS: which one?

MPLS offers guaranteed end-to-end quality (fits the critical core); SD-WAN brings agility and cost on access. Often combined: MPLS on critical links, SD-WAN for the rest.

Is SD-WAN secure?

Yes: encrypted tunnels, segmentation, and often integrated security (firewall, filtering). The NGFW is sized per site as needed.

Is equipment needed at each site?

Yes, one edge box per site, centrally managed. DataColoc prices equipment and access within the architecture.
