Priority fixes for street-one.de
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from Sectigo Limited had a 365-day validity period, longer than the 100-day maximum that applies from March 2027.
Why it matters: Under CA/Browser Forum Ballot SC-081v3, the maximum lifetime of public TLS certificates fell to 200 days on 15 March 2026 and falls to 100 days on 15 March 2027 and 47 days on 15 March 2029. Sites that renew by hand will need to renew far more often.
What to do: Move to automated issuance and renewal now, while you still have time to test it.
70% of E-Commerce & Marketplaces peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Enable
Structured data present
Observed: The homepage had no JSON-LD structured data.
What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
70% 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 street-one.de, 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.
