Software-Defined WAN (SD-WAN) – Explained
Learn what SD-WAN is, how it works, and its benefits.
If you were ever curious about what SD-WAN is or how it works, then this explainer video will teach you the basics. See how it is more effective and efficient compared to older technology managed by Command Line Interfaces (CLI).
SD-WAN offers greater flexibility, control, agility, and performance than traditional means of managing Wide Area Networks (WANs).
How Does SD-WAN Help Keep My Network Secure?
Security needs to be built into the SD-WAN design—not added later in response to security breaches. Centralized support for embedded security, firewalls, access points, and switches should help simplify and consolidate the overall management of equipment, especially at the branch and other distributed locations. Check for security that complements and integrates with third-party CASB or on-premises firewalls.
Security rules should be part of the policy and easy to implement, deploy, manage and change universally throughout the system—without any error-prone command-line interface (CLI) configuration.
The centralized, secure, global management system based on a single global policy should automate services and be easily changed for rapid response to changing conditions or new needs. User identity-based control provides an easy and intuitive way to define network access. Be sure you can identify users by name, roles or job functions.
