? How many domains does Apple secure?
Apple is the certificate authority for 1,469 active domains as of October 15, 2026 - 0.00% of every domain DNSniffer can attribute to an issuer.
? Is Apple gaining or losing market share?
The number of domains secured by Apple has grown by 0.55% over the last year (+8 domains).
? Which intermediate CAs does Apple sign from?
We have seen 8 intermediates under Apple, the busiest being “Apple Public Server RSA CA 1 - G1” with 1,443 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.
