They hack you behind your back to sell you a vulnerability detection service.
When visiting the website (browsing using my laptop and not my server), they display they detected vulnerabilities on my web server and that my IP address is malicious.
My web server just runs plain HTML and has not been flagged by any other website as malicious and has no suspicious traffic or resource consumption.
Coincidentally, exactly 1 minute after visiting this web site my personal web server gets a hack attempt to run a malicious software on it, the first attempt in 15 years of running without any issues.
Coincidence? I don't think so. There is 7884000 minutes in 15 years. And I don't spend my time browsing for server security either.
After the incident I come back to their website again and now they tell me to "upgrade my plan" and they don't display the information they had about my ip.
What they are doing is unethical as a company, pretty much a scam. Don't visit their web site if you own a web server.
