 Digital Experience Monitoring (DEX) provides visibility into device, network, and application performance across your Zero Trust organization.
 
-With DEX, you can monitor the state of your [WARP client](/cloudflare-one/connections/connect-devices/warp/) deployment and resolve issues impacting end-user productivity.
+With DEX, you can monitor the state of your [WARP client](/cloudflare-one/connections/connect-devices/warp/) deployment and resolve issues impacting end-user productivity. DEX is designed for IT and security teams who need to proactively monitor and troubleshoot device and network health across distributed environments. DEX is available on all Cloudflare Zero Trust and SASE plans.
