Unsafe network

I getting an Eset notification on my screen, "you are connected to an unsafe WiFi network, not safe for banking or making online payments. I am on a Comcast/Infinity network on my laptop. Why is that not safe?

I assume it means that Wi-fi Protected Access (WPA/WPA2/WPA3) is not enabled in the particular wi-fi network so the communication is not secured and could be eavesdropped.
