SRX2300 Firewall Datasheet

The SRX2300 firewall 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 SRX2300 empowers organizations to operationalize Zero Trust principles at scale while realizing their business objectives. The SRX2300 protects critical corporate assets with intrusion prevention system (IPS), follow-the-user and follow-the-application access policies, and Juniper’s AI-Predictive Threat Prevention. Furthermore, the SRX2300 works with Juniper 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 SRX2300 to act as a secure, fabric‑aware leaf in the data center spine‑leaf architecture.

The SRX2300 participates in the industry-first Connected Security Distributed Services Architecture, enabling organizations to scale horizontally and elastically and simplify the operational management of large-scale firewall networks. With this architecture, several SRX2300 platforms can work together as a single large logical firewall to provide higher performance and scale security.

The SRX2300 is powered by Juniper’s industry-leading Junos^® operating system that 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 SRX2300 hardware and software architecture provides cost‑effective security in a compact, scalable 1U form factor. Purpose built to protect network environments, the SRX2300 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 SRX2300 are offered in the data center, enterprise campus, and regional headquarters deployments with IMIX traffic patterns.

To increase trust and streamline operations, the SRX2300 features several built-in Zero Trust device capabilities, including an embedded Trusted Platform Module (TPM) 2.0 and cryptographically signed device ID. The SRX2300 supports RFC-compliant secure Zero-Touch Provisioning (sZTP) to efficiently, expediently, and remotely deploy products in your network. Additionally, the SRX2300 supports MACsec at wire speed, ensuring data integrity and confidentiality.

The SRX2300 firewall 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. 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 additional firewall engines across the various form factors (physical, virtual, containerized) are added, they can all be managed as one logical unit. This centralized management eliminates the complexity that has been an unintended consequence of a traditional scale-out approach.
