Product Overview

As data centers evolve from traditional architecture to distributed, the firewall’s role needs to expand. Rather than being a perimeter technology, firewalls need to be part of a security fabric woven throughout the network. A security fabric will ensure that security is maintained at every point of connection.

Juniper Networks SRX4700 next-generation firewall is integral to this new architecture, and it empowers organizations to operationalize security across their networks. This 1U, power-efficient firewall features built-in zero-trust, Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) fabric integration and AI-Predictive Threat Prevention to secure your network. The SRX4700 firewall delivers the industry’s highest throughput, per rack unit, at up to 1.4 Tbps, and supports 400 Gbps interfaces with wire speed MACsec.


Product Description

Juniper Networks® SRX4700 is a high-performance, next-generation firewall (NGFW) designed for service providers, cloud providers, and large enterprises. In addition, enterprises can deploy the SRX4700 as data center core and data center edge firewalls and as a secure SD-WAN hub. Combining industry-leading security effectiveness and carrier-grade routing with state-of-the-art switching, this platform delivers robust network security, effective threat protection, and comprehensive automation and mitigation capabilities.

SRX4700 delivers NGFW features that support the changing needs of cloud-enabled enterprise networks and data centers. Whether rolling out new services on an enterprise campus, connecting to the cloud seamlessly, complying with industry standards, or achieving operational efficiency, the SRX4700 empowers organizations to operationalize zero-trust principles at scale while realizing business objectives. The SRX4700 protects critical corporate assets with features such as intrusion prevention system (IPS), follow-the-user and follow-the-application access policies, and Juniper’s AI-Predictive Threat Prevention. Furthermore, SRX4700 works with Juniper’s cloud security solutions to secure hybrid-cloud environments with networkwide visibility and control, providing consistently secure on-premises and cloud environments.

For cloud providers, service providers, and enterprises, the hardware acceleration in SRX4700 protects data center core and edge workloads at Layer 7 at wirespeed with industry-leading security efficacy. The SRX4700 adheres to industry-standard EVPN type 5 and VXLAN protocols within these data centers, enabling the SRX4700 to act as a secure, fabric-aware leaf in the spine-leaf architecture and uniquely streamlining security workflows within the data center. And the SRX4700 does all this while delivering the highest firewall performance per rack unit of any data center firewall available today.

Service providers offering 4G and 5G services can take advantage of the proven software in SRX4700 that secures dozens of Tier 1 service providers around the world. Use cases supported with high-performance hardware acceleration include security gateway, Gi / N6 firewall, CGNAT, and roaming firewall. Service providers with power and space constraints can deploy the SRX4700 in both distributed and centralized locations and secure their networks at terabit speeds while consuming only a single rack unit within their data centers.

The SRX4700 participates in Juniper’s Connected Security Distributed Services Architecture, enabling organizations to scale both horizontally and elastically, and it simplifies operational management of large-scale firewall networks. With this architecture, several SRX4700 platforms can work together as a single large logical firewall to provide security at higher performance and scale.

The SRX4700 is powered by Junos® operating system, the OS that underpins and helps secure the world’s largest mission-critical enterprise and service provider networks. It is managed by Juniper Security Director Cloud, Juniper’s unified management experience that connects the organization’s current deployments with future architectural rollouts. Security Director Cloud uses a single policy framework enabling consistent security policies across any environment and expanding zero trust to all parts of the network from the edge into the data center. This provides unbroken visibility, policy configuration, administration, and collective threat intelligence all in one place.


Architecture and Key Components

The SRX4700 hardware and software architecture provides cost-effective security in a compact, scalable 1U form factor. Purpose built to protect network environments and provide Internet Mix (IMIX) firewall throughput of up to 1.4 Tbps, the SRX4700 incorporates multiple security services and networking functions on top of Junos OS, providing highly customizable threat protection, automation, and integration capabilities. Best-in-class advanced security capabilities on the SRX4700 are offered as 100 Gbps of NGFW, 110 Gbps of IPS, and up to 90 Gbps of IPsec VPN in the data center, enterprise campus, and regional headquarter deployments with IMIX traffic patterns.

Firewall throughput with application security 150 Gbps
IPsec VPN throughput (IMIX PowerMode IPsec (PMI) 90 Gbps
Intrusion prevention system 110 Gbps
NGFW throughput 100 Gbps
Connections per second 600,000
Maximum sessions 60 million

Built-in Zero Trust

To increase trust and streamline operations, the SRX4700 features several built-in zero trust device capabilities, including an embedded Trusted Platform Module (TMP) 2.0 and cryptographically signed device ID. The SRX4700 supports RFC compliant Secure Zero Touch Provisioning (sZTP) to deploy products in your network efficiently, expediently, and remotely. Additionally, the SRX4700 supports MACsec at wire speed, ensuring data integrity, and confidentiality.


Connected Security Distributed Services Architecture

The SRX4700 is part of Juniper’s Connected Security Distributed Services Architecture which revolutionizes data center security. With Juniper's Connected Security Distributed Services Architecture, firewall performance can scale horizontally by interconnecting traffic forwarding and security services across multiple geographic locations. Juniper’s solution also provides automated failover and backup nodes for both forwarding and inspection components. In addition to redundancy and load balancing, Juniper Connected Security Distributed Services Fabric simplifies how large-scale data center firewall networks are managed and operated. Regardless of how many firewall engines across the various form factors (physical, virtual, containerized) are added, they can all be managed as one logical unit. The centralized management eliminates the complexity that has been an unintended consequence of a traditional scale-out approach.
