The SRX2300 next-generation firewall (NGFW) protects small and midsized campus, data center, and regional headquarters networks. The 1 U, power-efficient device delivers up to 39 Gbps firewall throughput per rack unit and supports 100 Gbps interfaces with wire speed MACsec encryption to safeguard data in motion.
The SRX2300 integrates networking and security into a single platform. It features built-in zero-trust capabilities, EVPN-VXLAN fabric integration, and AI Predictive Threat Prevention for ultra-high security efficacy. Centrally managed by Juniper Security Director Cloud, the SRX2300 delivers high-performance IPsec VPN and unified policy management for securing your network reliably.
Table 1. SRX2300 Features and Benefits
