SRX1600 Firewall Datasheet

Product Overview

The firewall's role must expand as data centers evolve from traditional architectures to distributed ones. Rather than being a perimeter technology, firewalls need to be part of a security fabric woven throughout the network. A security fabric ensures that security is maintained at every point of connection.

Juniper's Connected Security Distributed Services Architecture, managed by Juniper Security Director Cloud, offers a high-performance, scalable, and easy-to-manage firewall solution to secure today’s distributed data centers. Juniper Networks SRX1600 Firewall is integral to this new architecture and empowers organizations to operationalize security across their networks. This 1U, power-efficient firewall features built-in Zero Trust, Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) fabric integration, and AI-Predictive Threat Prevention to secure your network.

Product Description

Juniper Networks^® SRX1600 Firewall is a high-performance, next-generation firewall (NGFW) designed to safeguard your enterprise campus edge, data center edge, and branch offices. It also supports roaming, SD-WAN large branch, and SD-WAN secure hub use cases. Combining industry-leading security efficacy and carrier-grade routing with state-of-the-art switching, this platform delivers robust network security, effective threat protection, and comprehensive automation and mitigation capabilities.

As network architectures become more distributed and decentralized, Juniper Networks SRX Series Firewalls ensure seamless integration with other Juniper and third-party networking platforms. At the same time, the NGFWs facilitate architectural transformation, taking organizations from on-premises to hybrid cloud environments seamlessly and cost-effectively. SRX Series Firewalls are the first to implement industry-standard Ethernet VPN (EVPN) Type 5 and Virtual Extensible LAN (VXLAN) protocols within data center environments, enabling the SRX1600 to act as a secure, fabric-aware leaf in the data center spine-leaf architecture.

The SRX1600 participates in Juniper’s Connected Security Distributed Services Architecture, enabling organizations to scale horizontally and elastically, simplifying the operational management of large-scale firewall networks. With this architecture, several SRX1600 platforms can work together as a single large logical firewall to provide higher performance and scale security.

The SRX1600 is powered by the Junos^® operating system, which underpins and helps secure the world’s largest mission-critical enterprise and service provider networks. It is managed by Juniper Security Director Cloud, Juniper’s 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.

Architecture and Key Components

The SRX1600 hardware and software architecture provides cost-effective security in a compact, scalable 1U form factor. Purpose built to protect network environments, the SRX1600 incorporates multiple security services and networking functions on top of Junos OS, providing highly customizable threat protection, automation, and integration capabilities. Best-in-class advanced security capabilities on the SRX1600 are offered in the data center, enterprise campus, and regional headquarters deployments with IMIX traffic patterns.

Built-In Zero Trust

The SRX1600 features built-in Zero Trust device capabilities to increase trust and streamline operations, including an embedded Trusted Platform Module (TPM) 2.0 and cryptographically signed device ID. The SRX1600 supports RFC-compliant Secure Zero Touch Provisioning (sZTP) to efficiently, expediently, and remotely deploy products in your network. Additionally, the SRX1600 supports MACsec at wire speed, ensuring data integrity and confidentiality.

Connected Security Distributed Services Architecture

The SRX1600 is part of Juniper’s Connected Security Distributed Services Fabric, revolutionizing data center security. With Juniper's Connected Security Distributed Services Architecture, firewall performance can scale horizontally by interconnecting traffic forwarding and security services across multiple locations. The Juniper solution also provides automated failover and backup nodes for forwarding and inspection components. In addition to redundancy and load balancing, Juniper’s Connected Security Distributed Services Architecture simplifies how large-scale data center firewall networks are managed and operated.

Regardless of how many firewall engines are added across the various form factors, they can all be managed as one logical unit. The centralized management eliminates the complexity that has been an unintended consequence of a traditional scale-out approach.
