Priority fixes for sat24.com

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

1. Priority 1 · Harden

   HTTP requests move to HTTPS

   Observed: A request to http://www.sat24.com/ 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 Cloudflare: Turn on Always Use HTTPS under SSL/TLS > Edge Certificates.

   92% of Weather Forecast peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.

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.

   On Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.

   39% of Weather Forecast peers do this.

3. Priority 3 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 2 external scripts without async or defer.

   What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.

   56% of Weather Forecast peers do this.

4. Priority 4 · Harden

   DMARC policy enforces quarantine or reject

   Observed: No DMARC record was found at _dmarc.sat24.com.

   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.

   31% of Weather Forecast peers do this.
