Software-Defined Wide Area Network (SD-WAN) Solution by ACCESSYSTEM® Technologies
Software-Defined Wide Area Network (SD-WAN) is a transformative technology that revolutionizes the way organizations connect and manage their wide area networks. It uses software-based controls to optimize network performance, enhance security, and reduce costs. SD-WAN is especially relevant in today’s cloud-driven environment, where applications and data are distributed across multiple locations.

Key Features of SD-WAN
- Centralized Management
- Application-Aware Routing
- Multi-Path Optimization
- Enhanced Security
- Cloud-Ready Architecture
SD-WAN allows for centralized control of network traffic through a software interface, simplifying configuration and monitoring.
Traffic is prioritized based on application requirements, ensuring optimal performance for critical services like video conferencing and VoIP.
SD-WAN uses multiple connection types (MPLS, broadband, LTE, 5G) and dynamically selects the best path for each data packet.
Built-in encryption, firewall capabilities, and integration with security protocols like Zero Trust improve data protection.
SD-WAN is designed to connect directly to cloud platforms, reducing latency and improving user experience.
Benefits of SD-WAN
