Networks in an organization are very important as a basis for communication and information sharing. in today's digital era, networks need to continuously adapt to meet increasingly complex and dynamic businesses. One effective approach to managing an organization's network is to use a Software Defined Wide Area Network (SD-WAN). Infrastructure modernization is needed to improve service quality. Our study was conducted in one of the leading telecommunication companies in Indonesia. The company faces challenges in improving services so that business performance is more effective and efficient than before. Previously, the company used a Wide Area Network (WAN) connection network, however, this network is no longer sufficient because internet traffic has now changed. Therefore, the company adopts SD-WAN which replaces Multi-Protocol Label Switching (MPLS) with multi-broadband internet with high bandwidth. It is encrypted with Internet Protocol Security (IPSec) Virtual Private Network (VPN) standards and simplifies branch management with one dashboard that includes many branches. The purpose of this study is to evaluate the adoption of SD-WAN architecture within the company. Evaluation is carried out on business processes that have implemented the SD-WAN network architecture based on The Open Group Architecture Framework (TOGAF). The evaluation results will be described in this study, and it is expected that the evaluation results can provide recommendations for improving the quality of SD-WAN adoption so that the company can align technology with business needs. The results of this study can also be a consideration for future researchers or practitioners who will implement SD-WAN in an organization.
