Improve security headers

Improve security with Netlify​

You can visite and scanne your website at https://securityheaders.com .

If security headers are missing then you will get D Grade even on Netlify.

You can Get A grade by just adding few lines of code.

In your root directory, create a file netlify.toml

[[headers]]
  for = "/*"
  [headers.values]
    X-Frame-Options = "DENY"
    X-XSS-Protection = "1; mode=block"
    Referrer-Policy = "no-referrer"
    X-Content-Type-Options= "nosniff"
    Strict-Transport-Security = "max-age=2592000; includeSubDomains; preload"
    Feature-Policy = "geolocation 'none'; midi 'none'; sync-xhr 'none';microphone 'none'; camera 'none'; magnetometer 'none'; gyroscope 'none'; speaker 'none'; fullscreen 'none'; payment 'none'"
    Content-Security-Policy= "default-src * 'unsafe-inline' 'unsafe-eval'; script-src * 'unsafe-inline' 'unsafe-eval'; connect-src * 'unsafe-inline'; img-src * data: blob: 'unsafe-inline'; frame-src *; style-src * 'unsafe-inline'"
