Who it suits
As a desktop unit it suits a small office, a shop or a branch that has no 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 TZ670 that means a line of up to about 1.6 Gbps.

Questions about the TZ670
What internet speed can the TZ670 handle?
SonicWall publishes a threat prevention throughput of 2.5 Gbps for the TZ670. Leaving headroom for busy hours, that suits an internet line of up to about 1.6 Gbps with protection switched on. With inspection off, its firewall throughput is 5 Gbps.
How many connections can the TZ670 handle?
SonicWall lists a maximum of 1.5 million concurrent sessions.
Does the TZ670 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 SonicWall subscription, and so do firmware updates and support. We quote the firewall with the licence term you choose.
Do you supply the TZ670 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.
