The EX4400 Ethernet Switch is a cloud-ready, AI-powered access switching platform with advanced security for high-performance campus deployments. It’s differentiated by features such as Power over Ethernet (PoE, PoE++), MACsec AES-256, microsegmentation using group-based policies (GBP), EVPN-VXLAN to the access layer, and flow-based telemetry.

As part of the underlying infrastructure for Juniper Mist™ Wired Assurance, the EX4400 is easy to onboard, configure, and manage. The Juniper Mist Cloud streamlines deploying and managing your campus fabric, while Mist AI simplifies operations and improves visibility into the performance of connected devices.
