As businesses grow, managing WAN across multiple sites becomes increasingly complex and costly with traditional solutions like MPLS. SD-WAN addresses these challenges by decoupling control functions from physical networks, simplifying management and reducing costs. Sangfor Secure SD-WAN builds on this foundation by providing safe, efficient, and reliable connectivity between locations. The Athena NGFW device acts as the edge gatekeeper, allowing only authorized traffic and protecting data confidentiality, integrity, and availability.
