Juniper Session Smart Router (SSR) is a tunnel-free, software-defined, and application-aware routing solution, purpose-built for secure, intelligent, and high-performance SD-WAN and multicloud networking. Designed for the needs of modern enterprises, SSR combines Mist AI and Zero Trust Security to ensure agile, scalable, and efficient routing across branches, data centers, and cloud platforms. As a result, businesses can optimize performance while enhancing security and simplifying operations.
Key Benefits:
Tunnel-Free Architecture: Unlike traditional WAN solutions, SSR leverages Secure Vector Routing (SVR) to eliminate tunnel overhead. Consequently, it delivers up to 50% bandwidth savings, improved application performance, and reduced latency. Moreover, this approach enables greater transparency and control.
Application-Aware Routing: With real-time traffic identification and prioritization, SSR delivers intelligent traffic steering. In addition, Mist WAN Assurance and Mist AI empower the platform with automated anomaly detection, session-level analytics, and deep visibility into user experiences. Thus, IT teams can respond faster to performance issues.
Zero Trust Security: SSR enforces a deny-by-default access model with directional control, segmentation, and integrated threat protection. Furthermore, the Advanced Security Pack enhances protection with URL filtering and Intrusion Detection and Prevention System (IDS/IPS), which guard against sophisticated cyber threats. Hence, it’s ideal for organizations with strict compliance requirements.
Scalability and Flexibility: Organizations can easily scale SSR across thousands of sites using physical appliances, virtual machines (VMware, KVM), or public clouds like AWS, Azure, and Google Cloud. Additionally, it runs natively on Juniper NFX Series hardware, offering deployment flexibility to match evolving infrastructure needs.
Streamlined Management: With Zero Touch Provisioning (ZTP), policy automation, and centralized control via Session Smart Conductor or Mist Cloud, SSR simplifies deployment and operations. Therefore, it significantly reduces administrative overhead.
Versatile Use Cases: SSR is ideal for SD-WAN, SD-Branch, multicloud connectivity, IoT integration, and data center edge routing. Consequently, it supports a wide range of digital transformation initiatives.
Operating on Junos OS, SSR integrates tightly with Juniper’s AI-Native Networking Platform, delivering AIOps capabilities, full-stack observability, and secure, autonomous networking. Altogether, it enables enterprises to modernize their networks while maintaining complete control, visibility, and security.
