Needs for a firewall
Hello,
Today, many companies use only a simply modem-router (like netgear). How to prove a company that it is very important to set up firewall (to protect his network) ? Which goods arguments could we find ? For example, if he has only a webserver (like iis 7) or other else ... thanks

How about volunteering to set up a simple one for free?
You just configure a transparent bridge firewall, log all DNS requests and the first packet of all outgoing SMTP transactions. After a week you show him the DNS and SMTP logs. Surely those logs will show violations of the company Internet usage policy.
