Priority fixes for matalan.co.uk
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 matalan.co.uk 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.
39% of E-Commerce & Marketplaces peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Harden
X-Content-Type-Options: nosniff
Observed: The homepage response did not include X-Content-Type-Options: nosniff.
What to do: Send X-Content-Type-Options: nosniff on all responses and make sure each file is served with the correct Content-Type.
On Cloudflare: Add the header with a response header transform rule.
64% of E-Commerce & Marketplaces peers do this.
Priority 3 · 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.
60% of E-Commerce & Marketplaces peers do this.
Priority 4 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for matalan.co.uk, 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.
16% of E-Commerce & Marketplaces peers do this.
