SRX300 Line of Firewalls for the Branch Datasheet

The SRX300 line of firewalls consists of secure SD-WAN routers that bring high performance and proven deployment capabilities to enterprises that need to build a worldwide network of thousands of remote sites. WAN or internet connectivity and Wi-Fi module options include:

• Ethernet, T1/E1, ADSL2/2+, and VDSL
• 3G/4G LTE wireless
• 802.11ac Wave 2 Wi-Fi

The SRX300 line offers a comprehensive suite of application security services, threat defenses, and intelligence services. The services include intrusion prevention system (IPS), application security user role‑based firewall controls, and cloud‑based antivirus, anti‑spam, and enhanced web filtering, protecting networks from the latest content‑borne threats. Integrated threat intelligence via Juniper’s SecIntel offers adaptive threat protection against Command and Control (C&C)‑related botnets and policy enforcement based on GeoIP. Customers can also leverage their custom and third‑party feeds to protect their networks from advanced malware and other threats. Integrating the Juniper Networks Advanced Threat Protection solution, the SRX300 line detects and enforces automated protection against known malware and zero‑day threats with a very high degree of accuracy.

As Juniper's simple and seamless management experience, Security Director Cloud is delivered in a single UI to connect customers' current deployments with their future architectural rollouts. Management is at the center of the Juniper Connected Security strategy and helps organizations secure every point of connection on their network to safeguard users, applications, and infrastructure.

Security Director Cloud enables organizations to secure their architecture with consistent security policies across any environment—on premises, cloud‑based, cloud‑delivered, and hybrid—and expands Zero Trust to all parts of the network, including the edge, data center, applications, and microservices. With Security Director Cloud, organizations have unbroken visibility, policy configuration, administration, and collective threat intelligence all in one place.

Juniper meets customers where they are on their journey, helps them leverage their existing investments, and empowers them to transition to their preferred architecture at the best pace for business by automating their transition with Security Director Cloud.

Secure the remote workforce anywhere with the fast, reliable, and secure access they need. Juniper Secure Edge delivers full-stack Security Service Edge (SSE) capabilities, including FWaaS, SWG, CASB with DLP, ZTNA, and advanced threat protection. It helps organizations protect access to web, SaaS, and on-premises applications and keep users secure wherever they are located.

Juniper Secure Edge, managed by Security Director Cloud, uses a single policy framework that enables security policies to be created once and applied anywhere, following users, devices, and applications wherever they go. Customers don't have to start from scratch when adopting cloud-delivered security. With our three-click wizard, customers can easily leverage existing campus edge policies and translate them into an SSE policy. Because it uses a single policy framework regardless of the deployment model, Secure Edge migrates existing security policies from traditional deployments to its cloud-delivered model in clicks, reducing misconfigurations and risk.

Whether securing remote users, campus and branch locations, private cloud, public cloud, or hybrid cloud data centers, Juniper provides unified management and unbroken visibility across all architectures. This makes it easy for ops teams to easily and effectively bridge their current investments with their future architectural goals, including SASE. 

Juniper has been consistently validated by multiple third-party tests as the most effective security technology on the market for the past three years, with 100% security efficacy across all use cases.

Mist WAN Assurance is a cloud service that brings AI-powered automation and service levels to Juniper SRX Series Firewalls, complementing the Juniper Secure SD-WAN solution. Mist WAN Assurance transforms IT operations from reactive troubleshooting to proactive remediation, turning insights into actions and delivering operational simplicity with seamless integration into existing deployments.

• SRX Series firewalls, deployed as secure SD-WAN edge devices, deliver the rich Junos streaming telemetry that provides the insights needed for WAN health metrics and anomaly detection. This data is leveraged within the Mist Cloud and AI engine, driving simpler operations, reducing mean time to repair (MTTR) and providing greater visibility into end user experiences.
• Insights derived from SRX Series SD-WAN gateway telemetry data allow WAN Assurance to compute unique “User Minutes” that indicate whether users are having a good experience.
• The Marvis assistant for WAN allows you to ask direct questions like “Why is my Zoom call bad?” and provides complete insights, correlation, and actions.
• Marvis Actions identifies and summarizes issues such as application latency conditions, congested WAN circuits, or negotiation mismatches.

The SRX300 line delivers fully automated SD-WAN to both enterprises and service providers.

• A Zero-Touch Provisioning (ZTP) feature simplifies branch network connectivity for initial deployment and ongoing management.
• SRX300 firewalls offer best-in-class secure connectivity.
• SRX300 firewalls efficiently utilize multiple links and load balance traffic across the enterprise WAN, blending traditional MPLS with other connectivity options such as broadband internet, leased lines, 4G/LTE, and more.
• Policy- and application-based forwarding capabilities enforce business rules created by the enterprise to steer application traffic toward a preferred path.

SRX300 firewalls are powered by Juniper’s Junos operating system, a proven, carrier‑hardened OS that underpins and helps secure the world’s largest mission‑critical enterprise and top 100 service provider networks.

The rigorously tested, carrier‑class, rich routing features, such as IPv4/IPv6, OSPF, BGP, and multicast, have been proven by over 15 years of worldwide deployments.

The SRX300 line also enables agile SecOps through automation capabilities that support Zero Touch Deployment, Python scripts for orchestration, and event scripting for operational management.
