# faq
? How many domains does Ziwit secure?
Ziwit is the certificate authority for 59 active domains as of October 15, 2026 - 0.00% of every domain DNSniffer can attribute to an issuer.
? Is Ziwit gaining or losing market share?
The number of domains secured by Ziwit has grown by 20.41% over the last year (+10 domains).
? Which intermediate CAs does Ziwit sign from?
We have seen 6 intermediates under Ziwit, the busiest being “TrustSign RSA DV SSL CA 2” with 42 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.
