Priority 1 · Harden
HTTP requests move to HTTPS
Observed: A request to http://www.mebius21.jp/ was not redirected to HTTPS.
Why it matters: Visitors who type the address or follow an old link start on unencrypted HTTP. A redirect moves them to the encrypted site before any cookies or form data are sent.
What to do: Add a permanent (301 or 308) redirect from every http:// URL to the same https:// URL at your CDN, load balancer or web server.
On Amazon CloudFront: Set the viewer protocol policy of each cache behaviour to Redirect HTTP to HTTPS.
95% of Job Portals, HR & Recruitment peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.
Priority 2 · Harden
