it's fair to point out that they're different markets, but how many words do you want your potential customers to have type into Google in order to give you money?you're never going to out-seo the Ethernet capture tool Wireshark, so "Wireshark tool wire Ethernet" isn't going to be any better than trying to search for Wireshark.
but I feel you. naming things is hard, even outside of computer science. my friend has a zero knowledge password entry system and we've sat and just talked about names for hours and hours and gone back and forth.
anyway, my two cents is change the name to something that's less impossible to SEO better than. you want your users to find you and "Wireshark" just seems like a difficult name for a product to compete against, especially given all the other animals in the sea. wirefish doesn't seem particularly claimed.
