Priority fixes for s22s.jp

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Enable

   Mobile viewport configured

   Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.

   Why it matters: Without it, phones render the page at desktop width and shrink it, which makes text tiny and hard to use.

   What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.

   98% of Workplace Productivity peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

2. Priority 2 · Harden

   HSTS kept for at least a year

   Observed: The homepage response did not include a Strict-Transport-Security header.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

3. Priority 3 · Harden

   DMARC policy enforces quarantine or reject

   Observed: The DMARC policy for s22s.jp was p=none, which asks receivers to take no action on failing mail.

   What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.

4. Priority 4 · Enable

   robots.txt published

   Observed: No robots.txt file was returned at the site root.

   What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.

   80% of Workplace Productivity peers do this.
