SRX4300 Firewall Datasheet

The SRX4300 delivers NGFW features that support the changing needs of cloud-enabled enterprise networks and data centers. Whether rolling out new services within an enterprise campus, connecting to the cloud seamlessly, complying with industry standards, or achieving operational efficiency, the SRX4300 empowers organizations to operationalize Zero Trust principles at scale while realizing their business objectives. The SRX4300 protects critical corporate assets with features such as an intrusion prevention system (IPS), follow-the-user and follow-the-application access policies, and Juniper’s AI-Predictive Threat Prevention. Furthermore, the SRX4300 works with Juniper’s cloud security solutions to secure hybrid-cloud environments with networkwide visibility and control, providing consistently secure on-premises and cloud environments.

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 SRX4300 to act as a secure, fabric-aware leaf in the data center spine-leaf architecture.

The SRX4300 participates in the industry-first 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 SRX4300 platforms can work together as a single large logical firewall to provide security at higher performance and scale.

The SRX4300 is powered by the Junos^® operating system (Junos OS), 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.

The SRX4300 hardware and software architecture provides cost-effective security in a compact, scalable 1U form factor. Purpose-built to protect network environments, the SRX4300 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 SRX4300 are ideal for data center, enterprise campus, and regional headquarters deployments with IMIX traffic patterns.

The SRX4300 features built-in Zero Trust device capabilities to increase trust and streamline operations, including an embedded Trusted Platform Module (TMP) 2.0 and cryptographically signed device ID. The SRX4300 supports RFC-compliant Secure Zero Touch Provisioning (sZTP) to efficiently, expediently, and remotely deploy products in your network. Additionally, the SRX4300 supports MACsec at wire speed, ensuring data integrity and confidentiality.

The SRX4300 is part of Juniper’s Connected Security Distributed Services Architecture, 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. Juniper’s 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 physical, virtualized, and containerized form factors, they can be managed as one logical unit. This centralized management eliminates the complexity that has been an unintended consequence of a traditional scale-out approach.
