Abstract: In the context of digital transformation, enterprises are evolving into multibranch conglomerates, adopting cloudbased services, and embracing decentralized models. However, this shift presents new challenges for network security. This article proposes a practical approach, based on the integration of 5G and SASE technologies, for secure access service edge (SASE) implementation. Leveraging 5G as the SDWAN transport network, the proposed solution connects data centers, hybrid clouds, and client endpoints. It deploys security access points of presence (POP) nodes nationwide, equipped with core modules such as Cloud Access Security Broker (CASB), Secure Web Gateway (SWG), Zero Trust Gateway, and FirewallasaService (FWaaS). Additionally, traditional security components can be selectively employed within these modules to enable usercentric security monitoring, access control, interception, and auditing capabilities. Practical implementation of this solution demonstrates its feasibility and effectiveness in various enterprise security protection scenarios.
