Overview
What is SD-WAN (Software-Defined Wide Area Network)?
SD-WAN (Software-Defined WAN) lets you use multiple links — leased lines, broadband, 4G/5G and MPLS — at every branch and manage them centrally through software.
Application-aware routing sends each application over the best available path in real time, while automatic failover keeps branches online if a link degrades. Policies are configured once in a central console and pushed to all sites.
The result is faster cloud access, better resilience and lower WAN cost, with zero-touch deployment for new branches.
Ideal for
Businesses with 5+ branches
Cloud and SaaS-heavy teams
Retail and QSR chains
Enterprises optimising MPLS
