? Is DigiCert Ireland gaining or losing market share?
The number of domains secured by DigiCert Ireland has grown by 45.01% over the last year (+528 domains).
? Which intermediate CAs does DigiCert Ireland sign from?
We have seen 8 intermediates under DigiCert Ireland, the busiest being “DigiCert QuoVadis 2G3 TLS RSA4096 SHA384 2023 CA1” with 1,403 domains. The full list, with per-intermediate counts, is on this page.
? Where does this number come from?
DNSniffer ingests Certificate Transparency logs continuously and records the issuer of the most recent certificate seen for each domain, then snapshots the per-issuer count once a day. It measures how much of the live web a CA currently secures, not how many certificates it has issued over its lifetime.
