Priority fixes for telia.se
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Social preview image set
Observed: The homepage had no og:image, so shared links may show without a preview image.
Why it matters: When your link is shared in chat apps and social networks, the preview image is what people see first.
What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.
59% of Telecommunications & Internet peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for telia.se, 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 Telecommunications & Internet peers do this.
Priority 3 · 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.
13% of Telecommunications & Internet peers do this.
Priority 4 · 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.
On Amazon CloudFront: Select HTTP/3 in the distribution's supported HTTP versions.
13% of Telecommunications & Internet peers do this.
