Product Description

The Juniper Networks® SRX1500 is a high-performance next-generation firewall and security services gateway that protects mission-critical networks at campuses, regional headquarters, and large branch offices. The SRX1500 provides best-in-class security, 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.

Hardware and software architectures on the SRX1500 provide significant performance improvements to a small 1 U form factor. The key to the SRX1500 hardware is the security flow accelerator 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 hardware components and virtualization to deliver high-speed firewall performance, application visibility, and intrusion prevention while lowering the 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.


SRX1500 Highlights

The SRX1500 fully complements next-generation firewall capabilities that help secure your network with an integrated solution that combines best-in-class application, content, and threat classification with SD-WAN, local switching, and easy policy management. Advanced application identification and classification enable greater visibility, enforcement, control, and protection over the network as they are tied to users regardless of location or device. It provides a detailed analysis of application volume and usage and fine-grained application control policies to allow or deny traffic based on dynamic application names or group names, and prioritization of traffic based on application information and context to reduce complexity across traditional, cloud, and hybrid IT networks.

By combining perimeter defenses with segmentation, the SRX1500 firewall provides a comprehensive suite of application security, threat defenses, and intelligence services to protect networks from content-borne threats. Integrated threat intelligence via Juniper Networks Advanced Threat Prevention (ATP) Cloud offers adaptive threat protection against command and control (C&C) solutions that leverage automated protection. This integration helps detect and enforce against known exploits, spyware, malware, and zero-day threats with an extremely high degree of accuracy using advanced AI techniques developed in conjunction with Juniper Threat Labs.

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 IPv, including IPv4/IPv6, OSPF, BGP, and multicast, have been proven in over 15 years of worldwide deployments.


Juniper Security Director Cloud

Security Director Cloud is Juniper’s simple and seamless management experience, delivered in a single UI to connect customers’ current deployments with their future architectural rollouts. Management is at the center of Juniper’s security strategy and helps organizations secure every point of connection on their network to safeguard users, data, and infrastructure.

Organizations can secure their architecture with consistent security policies across any environment—on-premises, cloud-based, cloud-delivered, and hybrid—and expand Zero Trust to all parts of the network, from the edge all the way into the data center and to the applications and microservices. With Security Director Cloud, organizations have unbroken visibility, policy configuration, administration, and collective threat intelligence all in one place.

Juniper meets our customers where they are on their journey, helps them leverage their existing investments, and empowers them to transition to their preferred architecture at a pace that is best for business by automating their transition with Security Director Cloud.


Juniper Secure Edge

Juniper Secure Edge secures workforces anywhere with the fast, reliable, and secure access they need. It delivers full-stack SSE capabilities, including FWaaS, SWG, CASB with DLP, ZTNA, and advanced threat protection to protect access to web, SaaS, and on-premises applications and provides users with security that follows them wherever they go. Juniper meets customers where they are and takes them where they want to go by leveraging what they have and extending their Zero Trust initiatives to a cloud-delivered architecture without breaking the bank or their ops team.

Juniper Secure Edge, managed by Security Director Cloud, uses a single policy framework that enables security policies to be created once to follow users, devices, and data wherever they go.

Customers don’t have to start from scratch when adopting cloud-delivered security. With our three-click wizard, customers can easily leverage existing campus edge policies and translate them into an SSE policy. Because it uses a single policy framework regardless of the deployment model, Secure Edge applies existing security policies from traditional deployments to its cloud-delivered model in just a few clicks, reducing misconfigurations and risk.

Whether securing remote users, campus and branch locations, private cloud, public cloud, or hybrid cloud data centers, Juniper provides unified management and unbroken visibility across all architectures. This makes it easy for ops teams to easily and effectively bridge their current investments with their future architectural goals, including SASE. Customers can manage security anywhere and everywhere, on-premises, in the cloud, and from the cloud, with security policies that follow users, devices, and data wherever they go, all from a single UI.

Users have fast, reliable, and secure access to the data and resources they need, ensuring great user experiences. IT security teams gain seamless visibility across the entire network while leveraging their existing investments, helping them transition to a cloud-delivered architecture at their own pace.

Juniper Secure Edge provides consistent security policies that follow the user, device, and data without having to copy over or recreate rule sets. It's easy to deploy cloud-delivered application control, intrusion prevention, content and web filtering, and effective threat prevention without breaking visibility or security enforcement. For the past five years, Juniper has consistently been validated by multiple third-party tests as the market's most effective security technology, with over 99% security efficacy across all use cases.
