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 threat prevention throughput figure. For the NSa 3700 that means a line of up to about 2.3 Gbps.

Does the NSa 3700 need a licence?

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.
