The Return On Investment of SD-WAN

**Executive summary:** This article analyzes the ROI drivers of SD‑WAN—reducing MPLS connectivity costs, lowering branch security expenses, and enabling network automation/co‑managed services—and argues that a converged SASE platform (Cato SASE Cloud with SSE 360) better solves SD‑WAN limitations by delivering integrated security (SWG, CASB, DLP, ZTNA, FWaaS), a global backbone, and simplified management to achieve greater cost savings and operational agility.
