Closing the SD-WAN Security Gap at the Edge

Distributed networks have shifted branch offices and remote workers from secondary exposure points to primary attack surfaces. This article explains how SD-WAN architectures improve connectivity and performance while simultaneously weakening traditional perimeter-based security assumptions if not paired with integrated controls. It outlines the operational importance of secure SD-WAN capabilities such as centralized policy enforcement, ZTNA, SSL inspection, DNS security, and branch-level intrusion prevention. For technology leaders, the key takeaway is that branch connectivity and branch security can no longer be treated as separate architectural domains.
