I like that it’s able give me insight into my website by highlighting areas where there might not only exist security issues but also other potential vulnerabilities which may need addressing such as performance/optimisation etc., It's very easy for non technical people (such us) who don't know much about computers at all just yet! Not exactly sure how well this works outside Europe so would have no way knowing if its worth using here too? Also cant see why some websites dont show up after i've run them through - think they do because sometimes when running certain sites im getting "not found" errors rather than actual warnings regarding possible risks / concerns from being hacked ect...
However thats something maybe could look more carefully upon before adding new features perhaps?? For now we're happy enough having those insights though :).
