I have a Nest Pro 6E network. It works fine but when I run a firewall test on www.grc.com using the Shields Up test it reveals that my firewall is vulnerable. The following are open:
80 - "The web is so insecure these days that new security "exploits" are being discovered almost daily. There are many known problems with Microsoft's Personal Web Server (PWS) and its Frontpage Extensions that many people run on their personal machines. So having port 80 "open" as it is here causes intruders to wonder how much information you might be willing to give away."
443 - "The presence of this secure web port in your system implies that this system is establishing secure connections with web browsers. The number one reason for doing this is the transmission of credit card information. This implies that the successful intruder could access the web server's credit card database and score bigtime. This is a VERY bad port to have open unless you are actually conducting secure web commerce"
I have searched all over the Google App and can find no way to improve my firewall settings. Is there something I'm missing?

What do you have between the Nest Wifi and the internet? A modem I guess, but is it a router with Wi-Fi too? If yes, the open ports might not be Nest Wifi, but the ISP equipment in front of Nest Wifi.
I just took the test on my Nest Wifi behind a modem in bridge mode, and did not get the same results.
If it's in fact the Nest Wifi Pro that has open ports, it can help to disable UPnP.

Hi oilheadrider,
Thanks for posting and we apologize for the inconvenience this has caused you. Nest Wifi Pro/Nest Wifi/Google Wifi settings like Universal Plug and Play (UPnP) and port forwarding may have allowed devices to bypass the firewall and have an open connection, leaving them potentially vulnerable.
It would be best to refer to this helpful guide to learn more about the security features of your Nest devices:
Keep us posted.
Thanks for helping, olavrb!
Best,
Dan

I am using Verizon Fios which includes the black brick that takes the fiber optic cable and coverts it to an ethernet port, but it does not have wifi capability. I did disable UPnP but it didn't change the results.

I escalated the thread in hope of getting some insight from Google.
