Priority fixes for weeronline.nl
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for weeronline.nl was p=none, which asks receivers to take no action on failing mail.
Why it matters: An enforcing DMARC policy helps receiving mail systems reject email that falsely claims to come from your domain, a common route for phishing your customers.
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. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Enable
Social preview image set
Observed: The homepage had no og:image, so shared links may show without a preview image.
What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.
58% of Weather Forecast peers do this.
Priority 3 · Harden
Content Security Policy present
Observed: The homepage response did not include a Content-Security-Policy header.
What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.
On Next.js: Next.js documents nonce-based CSP with middleware.
22% of Weather Forecast peers do this.

Priority 4 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for weeronline.nl, so any public certificate authority may issue for it.
What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.
On Cloudflare: Cloudflare documents which CAs its managed certificates need; include them in your CAA records.
8.9% of Weather Forecast peers do this.
