About the Juniper SRX345
The Juniper SRX345 is the flagship branch Services Gateway, offering the highest throughput and most expansion capacity in the SRX300 branch family. With 5 Gbps firewall, 1 Gbps IPS, 512,000 sessions, and six Mini-PIM expansion slots, the SRX345 handles large branch offices, regional distribution centres, and sites with complex multi-WAN requirements.
All Juniper SRX branch firewalls — including the SRX345 — support Juniper's Contrail Security and Security Director for centralised policy management and threat analytics. The SRX345 is Juniper's recommended platform for large distributed enterprise deployments where branch firewalls must handle significant localised traffic without backhauling to a central hub.
