SRX550 Services Gateway

The Juniper Networks® SRX Series Services Gateways for the branch combine next generation firewall and unified threat management (UTM) services with routing and switching in a single, high-performance, cost-effective network device


The SRX550 Services Gateway is an all-in-one solution that consolidates security, routing, switching, and WAN connectivity into a single 2 U device. It is a robust, highly flexible device for next-generation security, delivering enterprise-class networking for protecting today’s medium-to-large branch locations and supporting up to 5.5 Gbps firewall, 1 Gbps IPsec VPN, and 800 Mbps intrusion prevention system (IPS).

The SRX550 supports next-generation firewall capabilities such as IPS, application visibility and control, and unified threat management (UTM) features including antivirus, antispam, and enhanced Web filtering. Integrated security intelligence offers adaptive threat protection against Command and Control (C&C)-related botnets, malware, and Web application threats. The SRX550 also enforces policies based on GeoIP data from Juniper-provided feeds. IT organizations can use their own custom and third-party feeds for advanced threat protection.

The SRX550 is optimized for securing and connecting midsize or large branch locations that are geographically dispersed. It provides cost-effective, scalable integration of routing, security, and other midrange applications for branch sites. IT staff can deploy and manage SRX550 appliances in dispersed sites using the centralized Junos Space Security Director management platform.

NSS Labs, the world’s leading information security company, recommends the SRX550 because it delivers outstanding performance—even under the highest loads—in an architecture that consolidates next-generation firewall security with rich networking capabilities.


SRX Series Services Gateways for the branch are next-generation security gateways that provide essential capabilities that connect, secure, and manage workforce locations sized from handfuls to hundreds of users. By consolidating fast, highly available switching, routing, security, and next generation firewall capabilities in a single device, enterprises can protect their resources as well as economically deliver new services, safe connectivity, and a satisfying end-user experience. All SRX Series Services Gateways, including products scaled for Enterprise branch, Enterprise edge, and Data Center applications, are powered by Junos OS—the proven operating system that provides unmatched consistency, better performance with services, and superior infrastructure protection at a lower total cost of ownership
