Product Description

The Juniper Networks® SRX5400, SRX5600, and SRX5800 are next-generation firewalls (NGFWs) that deliver outstanding protection, market-leading performance, six nines reliability and availability, scalability, and services integration. These devices are ideally suited for service provider, large enterprise, and public sector networks, including:

  • Cloud and hosting provider data centers
  • Mobile operator environments
  • Managed service providers
  • Core service provider infrastructures
  • Large enterprise data centers

The SRX5400, SRX5600, and SRX5800 are an integral part of the Juniper Connected Security framework, which is built to protect users, applications, and infrastructure from advanced threats.

Delivering the highest level of protection against exploits, malware, and command and control (C&C) communications, these platforms feature a carrier-grade next-generation firewall and advanced security services such as application security, Content Security, intrusion prevention system (IPS), and integrated threat intelligence services.

For advanced protection, the SRX Series offers integrated threat intelligence services via Juniper Networks Advanced Threat Prevention (ATP), Juniper’s open threat intelligence platform in the cloud. Juniper ATP Cloud delivers actionable security intelligence to SRX Series devices to enable advanced protection against C&C-related botnets and Web application threats, as well as allowing policy enforcement based on GeoIP data—all based on Juniper-provided feeds. Customers may also leverage their own custom and third-party feeds for protection from advanced malware and other threats unique to their business environment. This advanced, customer-relevant, and consolidated threat intelligence service is delivered to the SRX Series on-premises from the cloud.

The SRX5400, SRX5600, and SRX5800 are supported by Juniper Networks Security Director, which enables distributed security policy management through an intuitive, centralized interface that enables enforcement across emerging and traditional risk vectors. Using intuitive dashboards and reporting features, administrators gain insight into threats, compromised devices, risky applications, and more.

Based on Juniper’s Dynamic Services Architecture, the SRX5000 line provides unrivaled scalability and performance. Each firewall can support near near linear scalability with the addition of Services Processing Cards (SPCs) and I/O cards (IOCs), enabling a fully equipped SRX5800 to support up to 3.36 Tbps firewall throughput. The SPCs are designed to support a wide range of services, enabling future support of new capabilities without the need for service-specific hardware. Using SPCs on all services ensures that there are no idle resources based on specific services being used—maximizing hardware utilization.

The scalability and flexibility of the SRX5000 line is supported by equally robust interfaces. The SRX5000 line employs a modular approach, where each platform can be equipped with a flexible number of IOCs that offer a wide range of connectivity options, including 1GbE, 10GbE, 40GbE, and 100GbE interfaces. With the IOCs sharing the same interface slot as the SPCs, the firewall can be configured as needed to support the ideal balance of processing and I/O. Hence, each deployment of the SRX Series can be tailored to specific network requirements.

The scalability of both SPCs and IOCs in the SRX5000 line is enabled by the custom-designed switch fabric. Supporting up to 960 Gbps of data transfer, the fabric enables the realization of maximum processing and I/O capability available in any particular configuration. This level of scalability and flexibility enables future expansion and growth of the network infrastructure, providing unrivaled investment protection.

The tight service integration on the SRX Series is enabled by Juniper Networks Junos® operating system. The SRX Series is equipped with a robust set of services that include stateful firewall, intrusion prevention system (IPS), denial of service (DoS), application security, VPN (IPsec), Network Address Translation (NAT), Content Security, quality of service (QoS), and large-scale multitenancy. In addition to the benefit of individual services, the SRX5000 line provides a low latency solution.

Junos OS also delivers carrier-class reliability with six nines system availability, the first in the industry to achieve independent verification by Telcordia. Furthermore, the SRX Series enjoys the benefit of a single source OS, and single integrated architecture traditionally available on Juniper’s carrier-class routers and switches.


The SRX5800 Firewall is the market-leading security solution supporting up to 3.36 Tbps firewall throughput and latency as low as 32 microseconds for the stateful firewall. The SRX5800 also supports 638 Gbps IPS and 338 million concurrent sessions. The SRX5800 is equipped with the full range of advanced security services and is ideally suited for securing large enterprise, hosted, or colocated data centers, service provider core and cloud provider infrastructures, and mobile operator environments. The massive performance, scalability, and flexibility of the SRX5800 make it ideal for densely consolidated processing environments, and the service density makes it ideal for cloud and managed service providers.


The SRX5600 Firewall uses the same SPCs and IOCs as the SRX5800 and can support up to 1.44 Tbps firewall throughput, 182 million concurrent sessions, and 245 Gbps IPS. The SRX5600 is ideally suited for securing enterprise data centers as well as aggregating various security solutions. The capability to support unique security policies per zone and its ability to scale with the growth of the network infrastructure make the SRX5600 an ideal deployment for consolidation of services in large enterprise, service provider, or mobile operator environments.


The SRX5600 Firewall uses the same SPCs and IOCs as the SRX5800 and can support up to 960 Gbps firewall throughput, 90 million concurrent sessions, and 172 Gbps IPS. The SRX5400 is a small footprint, high-performance firewall ideally suited for securing large enterprise campuses as well as data centers, either for edge or core security deployments. The ability to support unique security policies per zone and a compelling price/performance/footprint ratio make the SRX5400 an optimal solution for edge or data center services in large enterprise, service provider, or mobile operator environments.

Service Processing Cards (SPCs)

As the “brains” behind the SRX5000 line, SPCs are designed to process all available services on the platform. Without the need for dedicated hardware for specific services or capabilities, there are no instances in which a piece of hardware is taxed to the limit while other hardware is sitting idle. SPCs are designed to be pooled together, allowing the SRX5000 line to expand performance and capacities with the introduction of additional SPCs, significantly reducing management overhead and complexity. The high-performance SPC3 cards are supported on the SRX5400, SRX5600, and SRX5800 Firewalls.

I/O Cards (IOCs)

To provide the most flexible solution, the SRX5000 line employs the same modular architecture for SPCs and IOCs. The SRX5000 line can be equipped with one or several IOCs, supporting the ideal mix of interfaces. With the flexibility to install an IOC or an SPC on any available slot, the SRX5000 line can be equipped to support the perfect blend of interfaces and processing capabilities, meeting the needs of the most demanding environments while ensuring investment protection.

The third generation of IOCs from Juniper, the IOC3, delivers high throughput along with superior connectivity options including 100GbE, 40GbE, and high-density 10GbE interfaces. The IOC3 cards are supported on the SRX5400, SRX5600, and SRX5800.
