This is a great, free tool for doing a top-level analysis of a URL / domain. Nice to see Cloudflare offer this.

"Provide us a URL, and our scanner will compile a report containing a myriad of technical details: a phishing scan, SSL certificate data, HTTP request and response data, page performance data, DNS records, whether cookies are set to secure and HttpOnly, what technologies and libraries the page uses, and more."
