Product description

Juniper® WAN Assurance is a cloud service that brings automated operations and service levels to the enterprise access layer at the WAN edge. WAN Assurance is a key component of the Juniper AI-native SD-WAN solution, enabling IT teams to deliver superior user experiences across the WAN. When used in conjunction with Juniper® Wired and Wireless Assurance, the service transforms and unites all operations across network switches, IoT devices, access points, servers, printers, and other equipment. Juniper Session Smart Routers (SSR) and Juniper SRX Series Firewalls provide rich streaming telemetry that enables application health, WAN link health, and gateway health metrics and anomaly detection.

Marvis® AI further simplifies troubleshooting and streamlines the helpdesk with self-driving actions that automatically remediate issues. Marvis® AI Assistant turns insights into actions and fundamentally transforms IT operations from reactive troubleshooting to proactive remediation.

Juniper cloud services are 100% programmable using open APIs for full automation and/or integration with your IT applications.

 

WAN service-level experiences

Get operational visibility into user WAN experiences with service‑level expectations (SLEs) for SSRs or SRX Series Firewalls. Measure the impact of both gateway and WAN circuit health on end user application experiences. A WAN Link Health SLE, which accounts for network congestion, cable issues, and ISP network availability, delivers insights into how these factors are affecting a given network user or application. The Juniper Mist SLE dashboard helps identify root causes of suboptimal application experiences in just a few clicks to proactively isolate “needle‑in‑a‑haystack” problems (Figure 1).

WAN insights driven by Marvis AI

Know exactly how SSRs or SRX Series Firewalls are performing with metrics and insights down to the port level. These include CPU, memory utilization, bytes transferred, traffic utilization, and power draw. WAN Assurance also logs gateway events like configuration changes and system alerts. WAN and IPsec utilization insights tell you how much traffic traverses your encrypted tunnel versus your local breakout. You also gain visibility into per-user and per-application performance and experiences (Figure 3).

The Congestion SLE lets operators know if their network interfaces are being overutilized and causing poor user experience. With App Routing Insights, operators can figure out what is disproportionally using bandwidth and the best way to remediate the problem. Options could be to purchase more bandwidth, adjust capacity planning, or throttle certain traffic types (Figure 4).

Dynamic packet capture (dPCAP) gives operators insights on how to shorten MTTR and easily search for needle-in-a-haystack issues. Instead of recreating issues on the network to capture the right packets, Marvis AI will notice when an issue is occurring and automatically capture the appropriate packets for analysis.

 

Marvis AI Assistant for WAN

Marvis AI Assistant moves IT operations closer to the Self-Driving Network with simplified troubleshooting and performance analysis for helpdesk staff and network administrators.

Marvis Actions is a one-stop information center that provides visibility into site-wide network issues that need immediate attention. Use Marvis Actions to find issues affecting user experience and get recommendations into resolutions (Figure 5).

The Marvis Conversational Interface service allows IT teams to quickly get answers to troubleshooting questions. Simply ask a question in natural language, such as, “Why is my user’s video call experience bad?” and Marvis AI Assistant will provide recommendations to improve those experiences. Figure 6 shows Marvis AI Assistant informing IT of a WAN issue causing the CEO to have a poor video call experience.

Marvis Minis perform automated speed tests that give enterprises the ability to see if they are getting the full bandwidth that they purchased. Even when users aren’t present, operators are alerted to upstream network issues. This gives operators the opportunity to work on resolving issues before end users show up to the office.

SSRs are also available in other form factors, including certified white boxes (see the Session Smart Routing datasheet) or the Juniper® NFX Series Network Services Platforms.

WAN Assurance also supports the following SRX Series Firewalls when deployed as WAN gateways:

 

Choosing a WAN Edge device

When choosing a WAN edge platform within Juniper WAN Assurance, SSRs are generally recommended for their efficiency in network utilization, quick failover, rich telemetry, and integrated security, leveraging Secure Vector Routing and AI‑enhanced cloud management.

However, for networks already using Juniper's SRX Series Firewalls, integrating these with Mist enhances their capabilities and offers a more gradual transition to SD‑WAN. This enables immediate AI and cloud management benefits while accommodating familiar environments.

Additionally, organizations can configure their security capabilities directly on the SSR and/or the SRX through Mist.

Ultimately, the choice between SSR and SRX should align with your specific needs and goals, ensuring a seamless integration with Mist.

 

Branch in a box

The SSR400 line of routers offers a “Branch in a box” solution. It consolidates multiple branch functions, including Wi-Fi, switching, SD-WAN, and security into a single, unified, and easy-to-manage platform. This simplifies operations by eliminating the need to deploy and manage a complex array of separate devices from various vendors, significantly reducing a branch's physical footprint and lowering its total cost of ownership.

 

Advanced Security Pack

Session Smart Router’s Advanced Security Pack (Figure 7) integrates further security functionality into the routing fabric:

  • URL filtering prevents access to and from specific sites and to meet special business requirements
  • An Intrusion Detection and Prevention System (IDS/IPS) protects against advanced malicious attacks

These features eliminate the need for additional security appliances at the branch, providing this enhanced functionality within the Mist ecosystem of wired, wireless, and SD‑WAN. If more cloud‑integrated security is needed, customers have can add Juniper Secure Edge to the environment.

 

Meeting you where you are

When it comes to your network security, we want to help you on your terms. You can install the Advanced Security Pack standalone or alongside a Juniper SRX Series Firewall at your branch or data center.

The Advanced Security Pack can also be used to help you with your SASE Journey, giving you protection in the branch or data center before easily offloading that traffic to an SSE such as Juniper Secure Edge.

 

Risk profiling driven by AI

WAN Assurance is a key component of the Risk Profiling solution that brings network security to the distributed network edge. Risk Profiling provides visibility into infected wired or wireless clients that’s observable within the cloud and assigns a threat score determined by the Juniper ATP cloud. From within the cloud, you can geospatially locate infected devices and take one‑touch mitigation actions like ban or deauthenticate.
