Juniper SRX345 Network Gateway

The Juniper SRX345 gateway is a 1U rack-mountable services gateway designed to provide scalable, secure connectivity for cloud-enabled enterprise networks. With up to 5 Gbps firewall throughput and 800 Mbps IPsec VPN performance, the SRX345 supports midsized and large distributed locations and up to 200 users, and includes high-density native Gigabit Ethernet ports to accommodate growing network traffic. It operates across physical, network, and application layers and can be centrally managed via Junos Space Security Director for unified control of the security infrastructure.

Advantages

The SRX345 combines next-generation firewall capabilities and unified threat management (UTM) features to detect and mitigate threats proactively. It supports both IPv4 and IPv6, common routing protocols such as BGP, OSPF and MPLS, and provides strong cryptographic support including IPsec and SSL/TLS. The 1U form factor, substantial internal memory and flash storage, and rack-mount design make it suitable for deployment in branch and distributed enterprise environments while allowing centralized management.

Suitable for

• Securely connecting midsized and large branch offices
• Distributed enterprise sites requiring centralized security management
• Locations needing high-density Gigabit Ethernet connectivity
• Networks using IPv4/IPv6 and dynamic routing protocols (BGP, OSPF, MPLS)

How to use

Install the SRX345 in a standard 1U rack position and connect the WAN and LAN networks to the appropriate Gigabit Ethernet ports. Configure basic system settings and network interfaces using the Junos OS CLI or the Junos Space Security Director management platform. Define firewall policies, VPN tunnels (IPsec), and routing protocols (BGP, OSPF, MPLS) according to your network design. Monitor performance and security events via the centralized management console to ensure ongoing protection.

Recommendations

For reliable performance, keep Junos OS and Security Director up to date, size the device for expected throughput and VPN load, and centralize policy management through Junos Space Security Director to simplify administration across distributed sites.
