SDWAN solution for consumer industry

[Leo4]

Can someone help me with this? 

I want to build scenarios for overall SDWAN solution for consumer industry that do SDWAN from starting. So,

I was planned to place MX 105 appliance at HQ. Except from MX appliance, do I need to buy firewall appliance for security for my HQ.?

At the branches site, MX 68 will be used . Except from MX, do I need other additional FW appliance, router and switch.

The main purpose is I want to build topology for Meraki SDWAN for consumer industry company. Is there any reference topology design I can study. 

Thanks you all. Have a good day.

The Meraki MX is a Securtiy Appliance (firewall) already, while also enabling SDWAN, so in principle no, you do not need another firewall or security appliance.

If for any reason you do not like the Security features of Meraki, could technically use it as a VPN Concentrator(/passthrough mode) to empoloy the use of Meraki SDWAN, while using some other vendor for security/firewalling.

But as the MX includes both features, you'd might as well stick with the Meraki MX instead.
