Analyze security headers to see if you follow best practices
Inspired by https://owasp.org/www-project-secure-headers/
Security Headers Check makes a GET request to the specified URL, analyzes the headers, and shows the results to you in an easy-to-understand way.
You also get the http code and all raw headers in the bottom field
Created with Lazarus
During development I used https://www.serpworx.com/check-security-headers/ to test, as they implement a number of headers.
