Priority fixes for miro.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Structured data present
Observed: The homepage had no JSON-LD structured data.
Why it matters: Structured data helps search engines understand your organization, products or articles, and is needed for some rich results.
What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
50% of Workplace Productivity peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from Amazon had a 197-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 Workplace Productivity 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.
16% of Workplace Productivity peers do this.
Priority 4 · Harden
DNSSEC signed
Observed: No DS record was found for miro.com at its parent zone, so its DNS answers are not DNSSEC-signed.
What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.
On Amazon Route 53: Enable DNSSEC signing for the hosted zone and establish the chain of trust at the registrar.
12% of Workplace Productivity peers do this.
