Juniper Networks makes networking hardware and software — primarily routers, switches, Wi-Fi access points, and firewalls — sold to enterprises, cloud providers, and telecom carriers. Customers use Juniper's products to build and run networks that carry internet traffic, connect employees to corporate applications, link data centers, and deliver cloud services. Juniper operates across three core areas: WAN routing (MX, PTX, ACX series routers for carriers and cloud providers), campus and branch networking (Wi-Fi access points and switches for enterprise environments), and data center switching (QFX series switches and Apstra automation software). Security products, primarily SRX firewalls, are bundled across all three areas. Juniper sells directly to large cloud and service provider customers and through distributors and VARs to enterprise customers, operating in over 150 countries. Revenue comes from hardware sales, software licenses, and services — including multi-year maintenance contracts and SaaS subscriptions. A key strategic priority is shifting from lumpy hardware revenue toward recurring SaaS revenue through its Mist AI platform, acquired in 2019, which uses AI to automate network troubleshooting and management. Juniper is also targeting AI data center infrastructure, including high-speed networking for GPU clusters, and pitches its AI-native networking capabilities as a differentiator against Cisco, its primary competitor across all segments.
