It has a ton of false positive. Example, for google.com it shows 1 of the 2 vulnerabilities as follows Joomla!, headers - 1.5 with CVSS severity score of [10] Google running Joomla???? Highly unreliable
It works and matched what an external scan of our site reported. Great tool to have in-house.
This is an awesome utility and recommend it to everyone. It's scary knowing just how vulnerable the websites you commonly go to are.
It will spam your main screen with security articles randomly throughout the day. No ads, just relevant articles, but it will pop up over anything if you are presenting and forget to close chrome beforehand. Would be perfect if there was a way to turn that off, but there isn't. Until then, gotta remove it.
