SRX300 Services Gateways

Juniper Networks® SRX300 line of services gateways delivers a next-generation networking and security solution that supports the changing needs of cloudenabled enterprise networks


The SRX300 line of services gateways delivers a next-generation security, networking, and SD-WAN solution that helps you support the changing needs of your cloud-enabled enterprise network. Whether you’re rolling out new services and applications across multiple locations, connecting to the cloud, or improving operational efficiency, the SRX300 line provides scalable, secure, and easy-to-manage connectivity.

As your network traffic grows, high-density native Gigabit Ethernet ports available on the SRX300 platforms provide secure connectivity to help you keep pace. Next-generation firewall and unified threat management (UTM) capabilities also make it easier to detect and proactively mitigate threats to improve the user and application experience.


Four SRX300 Services Gateway models are available to address the security needs of different environments:

  • SRX300: 1 Gbps firewall with 300 Mbps IPsec VPN. This device consolidates security, routing, switching, and WAN connectivity in a small, fanless desktop device ideal for retail-type offices with up to 50 users.

  • SRX320: 1 Gbps firewall with 300 Mbps IPsec VPN. This compact desktop device features high-performance security, routing, switching, and WAN connectivity for small, distributed enterprise locations with up to 50 users.

  • SRX340: 3 Gbps firewall with 600 Mbps IPsec VPN in a 1 U form factor. This compact device consolidates security, routing, switching, and WAN connectivity to meet the needs of midsize, distributed enterprise locations with up to 100 users.

  • SRX345: 5 Gbps firewall with 800 Mbps IPsec VPN in a 1 U form factor. This device securely connects midsized and large distributed enterprise locations with up to 200 users.

SRX300 Services Gateways operate at the physical, network, and application layers to secure a range of locations across the distributed enterprise, from small retail offices to midsized or large branches. Geographically dispersed throughout the network, the SRX300 platforms can be centrally deployed and managed using the Junos Space Security Director platform, which provides a “single pane of glass” for managing the entire security infrastructure.
