What is Cisco SDA?

Cisco Software-Defined Access (SDA) is a network architecture that automates network provisioning, simplifies management, and improves security. It uses a centralized controller (DNA Center) to define and enforce policies across the network, abstracting the underlying hardware and enabling intent-based networking. SDA is commonly used to segment networks for security purposes, automate device onboarding, and provide consistent user experiences across wired and wireless networks.
