SRX300 desktop firewall for small branches

The SRX300 is a desktop firewall appliance that combines security, routing, switching and WAN connectivity for small branch or retail offices. It runs Junos Software Base providing firewall, NAT, IPSec, routing, MPLS and switching features in a single unit. System memory is 4 GB. The rack-mount kit is not included.

Throughput limits of the integrated platform

Firewall throughput reaches up to 1.9 Gbps while IPSec VPN throughput peaks at 336 Mbps. Average power consumption is 24.9 W from an external AC power supply. The chassis measures 12.63 x 1.37 x 7.52 in and weighs 4.38 lb. Buyers who need higher session capacity or faster VPN encryption must choose a larger model.

4 GB memory determines concurrent session capacity

The fixed 4 GB of system memory sets the maximum number of concurrent sessions and the size of routing tables the device can handle. This capacity fits typical small-office workloads but will limit deployments that require large route tables or heavy application identification. Environments expecting sustained high-session loads should verify the memory ceiling before purchasing.

Questions about this item

Which SRX300 model should I choose for a small branch that needs up to 1.9 Gbps firewall throughput?

The SRX300-SYS-JB model delivers up to 1.9 Gbps firewall performance and 336 Mbps IPSec VPN throughput, consolidating security, routing, switching, and WAN connectivity in a single desktop appliance.

What does the 1.9 Gbps firewall figure mean when the unit is handling live traffic?

That 1.9 Gbps rating represents the maximum firewall throughput the SRX300 can sustain under ideal conditions; actual throughput will be lower when inspection features such as IPS, application identification, or UTM are enabled.

What management interface does the SRX300 use and what throughput does it cap at?

The SRX300 is managed through Junos OS via CLI, Web UI, or Junos Space; the control-plane interface does not limit the 1.9 Gbps firewall or 336 Mbps VPN data-plane throughputs.
