Priority fixes for nationalrail.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 nationalrail.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.
40% of Trains & Public Transport peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Harden
security.txt published
Observed: No valid /.well-known/security.txt with a Contact field was returned.
What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
On Cloudflare: Cloudflare Security Center can serve a security.txt file for the zone.
9.5% of Trains & Public Transport peers do this.
Priority 3 · Recover
Nameservers spread across providers
Observed: All nameservers for nationalrail.co.uk belong to a single operator.
What to do: Treat this as an advanced step. Add a secondary DNS provider through zone transfers or a multi-provider setup, then test changes carefully, since both providers must stay in sync.
On Cloudflare: Cloudflare supports zone transfers for primary or secondary DNS setups on eligible plans.
15% of Trains & Public Transport peers do this.
