# faq
? How many domains does GeoSSL secure?
GeoSSL is the certificate authority for 2,681 active domains as of October 14, 2026 - 0.00% of every domain DNSniffer can attribute to an issuer.
? Is GeoSSL gaining or losing market share?
The number of domains secured by GeoSSL has grown by 28.22% over the last year (+590 domains).
? Which intermediate CAs does GeoSSL sign from?
We have seen 4 intermediates under GeoSSL, the busiest being “GeoSSL DV TLS CA” with 2,576 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.
