Software-defined wide area networking for multi-site businesses. Better performance, lower cost and centralised management — replacing expensive legacy MPLS.
Get a Free AssessmentSD-WAN — Software-Defined Wide Area Networking — is a technology that replaces or augments traditional MPLS (Multi-Protocol Label Switching) connections between business sites. Instead of routing all traffic through expensive dedicated circuits, SD-WAN intelligently routes traffic across multiple connections — broadband, 4G/5G, MPLS — selecting the best path in real time based on application requirements and network conditions.
The result is better performance for cloud applications and real-time traffic, lower cost than pure MPLS, and centralised management of all sites from a single dashboard. For multi-site businesses, SD-WAN is typically one of the highest-value IT changes available.
Modern SD-WAN solutions increasingly incorporate security functions — firewalling, secure web gateways, zero-trust network access — into the same platform. This is known as SASE (Secure Access Service Edge) and is rapidly becoming the standard architecture for enterprise connectivity. Open Way Technologies has access to leading SASE platforms through our provider relationships.
BT's switch-off of the PSTN in 2027 affects not just voice but also some legacy data circuits. Organisations reviewing their connectivity ahead of 2027 should assess SD-WAN at the same time — the timing is perfect to modernise both.
