Does Our Small Office Need a Firewall/VPN Hardware

We are a four person office with a Verizon DSL connection to the internet and we have a Static IP.  For many years we have had a Cisco Pix 501 installed between the DSL modem and the the outside internet. We want to switch over to Business FIOS to get better speeds and also we will be migrating to a virtual PBX system.  Most of the state of the art firewall hardware out there is expensive and while I am somewhat knowledgeable, I am not qualified to install such hardware and configure it properly, and so we will have to hire a network consultant.  We also do not have a dedicated server, and operate on a peer to peer basis with my computer acting as a server surrogate.  So my question is this: do we really need to have firewall hardware?  Accessing our system from the outside works quite well with GoToMyPC, so a VPN is not really a necessity.  In addition, I am assuming that the FIOS modem/router will have built in firewall protection which may be perfectly adequate for our purposes, and we could install additional protection with a software based firewall system.  Am I right?

I am not sure which specific version of the Verizon router you will receive but more than likely it already has a standard firewall build in that will work fine for your office. You can also check out the Cisco Small Business Series of routers which work well and are much easier to manage than the Cisco Pix.

I have to agree with ITguy850 on this question.  I don't think you need to spend to much on a high end router.

Normally routers come with some rudimentary firewall built-in, usually it fits purpose.
Linksys high-end devices are sligtly cheaper and with less sales pressure (like free support for life) than Cisco prime grade produce...
