Product Description

The Juniper Networks® SRX4600 next-generation firewall protects mission-critical data center and campus networks for enterprises, service providers, and cloud providers. It is an integral part of the Juniper® Connected Security framework, which extends security to every point on the network to safeguard users, data, and infrastructure from advanced threats. SRX4600 Firewall integrates networking and security in a single platform to deliver industry-leading intrusion prevention and malware protection with high performance throughput, IPSEC VPN, high scalability, and easy policy management to secure the network reliably.

Advanced application identification and classification enables greater visibility, enforcement, control, and protection over network traffic, application access, and data. The firewall provides a detailed analysis of application volume and usage, fine-grained application control policies to allow or deny traffic based on dynamic application names or group names. Traffic is prioritized based on application information and context to reduce complexity across traditional, cloud, and hybrid IT networks. 

SRX4600 also delivers fully automated SD-WAN to both enterprises and service providers. Due to its high performance and scale, the SRX4600 acts as a VPN hub and terminates VPN/secure overlay connections in various SD-WAN topologies.



It is managed by Juniper Security Director Cloud, a 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.

The SRX4600 is powered by Junos® operating system, the industry- leading OS that keeps the world’s largest mission-critical enterprise and service provider networks secure.


Architecture and Key Components

The SRX4600 hardware and software architecture provides cost-effective security in a small 1 RU form factor. Purpose built to protect network environments and provide Internet Mix (IMIX) firewall throughput of up to 400 Gbps, the SRX4600 incorporates multiple security services and networking functions on top of Junos OS. Best-in-class security and advanced threat mitigation capabilities on the SRX4600 are offered as 33 Gbps of next-generation firewall, 45.4 Gbps of intrusion prevention system (IPS), and up to 44 Gbps of IPsec VPN in the data center, enterprise campus, and regional headquarters deployments with IMIX traffic patterns.
