Priority fixes for antena3.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.antena3.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.
31% of Entertainment & Video Streaming peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Harden
Framing restricted
Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.
What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.
43% of Entertainment & Video Streaming peers do this.
Priority 3 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from GlobalSign nv-sa had a 396-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.
50% of Entertainment & Video Streaming peers do this.
Priority 4 · 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.
18% of Entertainment & Video Streaming peers do this.
