Cisco Software-Defined Access (SD-Access)

Cisco Software-Defined Access (SD-Access) is a comprehensive network solution designed to simplify and secure enterprise networks by automating policy enforcement and segmentation across wired and wireless environments. It leverages a controller-based architecture using Cisco Catalyst Center to provide centralized management, automation, and deep network insights. Key features include AI/ML-driven endpoint identification and grouping, group-based access policies, and virtual network overlays that enable scalable segmentation and mobility. SD-Access enforces zero-trust security principles by continuously analyzing endpoint behavior, verifying trust, and rapidly containing threats to reduce risk and improve compliance. The solution integrates Cisco Identity Services Engine (ISE) for dynamic policy enforcement and Cisco TrustSec for software-defined segmentation using Security Group Tags (SGTs). Benefits include operational simplicity through automation, unified wired/wireless policy management, scalable network expansion, and enhanced digital experience assurance with proactive monitoring and analytics. SD-Access supports seamless IT and OT integration, consistent multidomain policy enforcement, and network-wide resiliency, helping organizations achieve secure, efficient, and scalable network operations with measurable ROI in reduced deployment times, lower operational costs, and improved security posture.
