    Fortigate-40F Firewall Appliance

    THIS IS A PERFECT FW for Home or small business. I retired as a Network and security Systems Engineer. my only experience are with Palo Alto, Checkpoint and Cisco ASA. I have not touch Fortinet products. in summary, they can be close , actually very close to the aforementioned products. Yes, I have the entry product (for my home use only) but it preforms very well. It does not have the granularity of control of a NGFW because I have a entry level modelI will give it 5 stars as it performs very well, no speed issues and most importantly I was able to build rule sets that allowed me to have 10 R

    great for the price

    does all the bsic firewall/networking stuff I need at a reasonable price. I tried so many other expensive routers but they all fell short of vlan requirements. this firewall does vlan layer 3 well. it takes a while to get used to the interface and how it manages objects, so be sure you have time to spare for learning before you deploy to prod.logging all has to go to syslog so be sure you can install splunk and/or cacti to get the long term data you need. the appliance has some logging and widget/graphs but does not provide a long enough time range.

    STAY AWAY

    Installing this thing was/is an unmitigated disaster! NOTHING works. The instrucations and "quick set up guide" are useless, noting more then a bunch a photos of the labling the light.. useless until you get it configured. You can not get it set up until it is registered; you can not register as AMAZON is not listed as an "approved reseller." What a waste of money and time.
