A Software-Defined Wide Area Network (SD-WAN) provides centralized management, enabling organizations to apply security policies and updates uniformly across the network with ease. This centralized approach not only simplifies the administration of the network but also ensures consistent security measures are in place throughout, addressing the organization's need for improved security management. While the option of improved performance through optimized routing is a benefit of SD-WAN, it is not inherently a security benefit. Reduction in operational costs mainly pertains to financial aspects rather than direct security enhancements. Similarly, the ability to dynamically change network paths is a performance-related benefit, but it's not the primary security advantage that SD-WAN offers.
