Enterprise Firewall, teeny tiny office

Hey all,

I've been brought up always putting in either Meraki or WatchGuard firewalls but, the current shop I'm working on kitting out, (new customer for our MSP) has literally nothing going on but a couple workstations. No port forwarding, nothing. They currently have a Meraki with a license that's due to run out next month.

I'm having a hard time quoting the $1,5k for a 3 year license when all the workstations will have S1 and Guardz (new product for us but does offer some safe browsing features). Seem like a very basic Firewall with some cloud function would be best.

Thoughts?

Thanks in advance!
