Who it suits
As a rackmount unit it suits a head office, campus or data centre with a server rack. With protection switched on, plan for an internet line of no more than about two-thirds of the IPS throughput figure. For the SRX1500 that means a line of up to about 2 Gbps.

Questions about the SRX1500
What internet speed can the SRX1500 handle?
Juniper publishes an IPS throughput of 3 Gbps for the SRX1500. Leaving headroom for busy hours, that suits an internet line of up to about 2 Gbps with protection switched on. With inspection off, its firewall throughput is 9 Gbps.
What ports does the SRX1500 have?
16 x 1GbE (12 copper + 4 SFP), 4 x 10GbE SFP+.
How many connections can the SRX1500 handle?
Juniper lists a maximum of 2 million concurrent sessions and 90,000 new sessions per second.
Does the SRX1500 need a licence?
The hardware works as a basic firewall on its own. Protection features such as intrusion prevention, web filtering and anti-malware need an active Juniper subscription, and so do firmware updates and support. We quote the firewall with the licence term you choose.
Do you supply the SRX1500 with installation?
Yes. We supply it with its licence registered, install and configure it at your site, and hand over the logins and documentation. Ask for a quote on this page.
