Product Description

The Juniper Networks® SRX1500 is a high-peformance next-generation firewall and security services gateway that protects mission-critical networks at campuses and regional headquarters. The SRX1500 provides best-in-class security and threat detection and mitigation capabilities, integrating carrier-class routing and feature-rich switching in a single platform.

The SRX1500 delivers a next-generation security solution that supports the changing needs of cloud-enabled enterprise networks. Whether rolling out new services in an enterprise campus, connecting to the cloud, complying with industry standards, or achieving operational efficiency, the SRX1500 helps organizations realize their business objectives while providing scalable, easy-to-manage, secure connectivity and advanced threat detection and mitigation capabilities. The SRX1500 protects critical corporate assets as a next-generation firewall, acts as an enforcement point for cloud-based security solutions, and provides application visibility and control to improve the user and application experience.

A combination of hardware and software architectures on the SRX1500 add significant performance improvements to a small 1 U form factor. The key to the SRX1500 hardware is the security flow accelerator, a programmable high-speed Layer 4 firewall chip, and a robust x86-based security compute engine for advanced security services like application visibility, intrusion prevention, and threat mitigation capabilities. The SRX1500 software architecture leverages these programmable hardware components and virtualization to deliver high-speed firewall performance, application visibility, and intrusion prevention while lowering total cost of ownership (TCO).

The SRX1500 is purpose-built to protect 10GbE network environments, consolidating multiple security services and networking functions in a highly available appliance. It supports up to 9.2 Gbps of firewall performance, 3.3 Gbps of intrusion prevention, and 4.5 Gbps of IPsec VPN in enterprise campus, regional headquarters, and data center deployments.


SRX1500 Highlights

The SRX1500 delivers a full complement of next-generation firewall capabilities that use advanced application identification and classification to enable greater visibility, enforcement, control, and protection over the network. It provides a detailed analysis of application volume and usage, fine-grained application control policies to allow or deny traffic based on dynamic application name or group names, and prioritization of traffic based on application information and context.

The SRX1500 recognizes more than 4,275 applications and nested applications in plain-text or SSL encrypted transactions. The SRX1500 also integrates with Microsoft Active Directory and combines user information with application data to provide network-wide application and user visibility and control.

For the perimeter, the SRX1500 Firewall offers a comprehensive suite of application security services, threat defenses, and intelligence services to protect networks from the latest content-borne threats. Integrated threat intelligence via Juniper Networks ATP Cloud offers adaptive threat protection against command and control (C&C)-related botnets and policy enforcement based on GeoIP. Integrating the Juniper Networks Advanced Threat Prevention Cloud solution, or working with the Juniper Networks ATP Appliance, the SRX1500 detects and enforces automated protection against known malware and zero-day threats with an extremely high degree of accuracy.

The SRX1500 enables agile SecOps through automation capabilities that support Zero Touch Deployment, Python scripts for orchestration, and event scripting for operational management.

The SRX1500 delivers fully automated SD-WAN to both enterprises and service providers. A Zero-Touch Provisioning (ZTP) capability simplifies branch network connectivity for initial deployment and ongoing management. Due to its high performance and scale, the SRX1500 acts as a VPN hub and terminates VPN/secure overlay connections in the various SD-WAN topologies.

The SRX1500 Firewall runs Juniper Networks Junos® operating system, a proven, carrier-hardened network OS that powers the top 100 service provider networks worldwide. These rigorously tested carrier-class routing features of IPv4/IPv6, OSPF, BGP, and multicast have been proven in over 15 years of worldwide deployments.
