Priority fixes for tendacn.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.tendacn.com.
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.
52% of Smart Home & Lifestyle peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
42% of Smart Home & Lifestyle peers do this.
Priority 3 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from DigiCert Inc had a 182-day validity period, longer than the 100-day maximum that applies from March 2027.
What to do: Move to automated issuance and renewal now, while you still have time to test it.
59% of Smart Home & Lifestyle peers do this.
Priority 4 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for tendacn.com, 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.
15% of Smart Home & Lifestyle peers do this.
