# faq
? How many domains does UniTrust secure?
UniTrust is the certificate authority for 4,174 active domains as of October 15, 2026 - 0.00% of every domain DNSniffer can attribute to an issuer.
? Is UniTrust gaining or losing market share?
The number of domains secured by UniTrust has grown by 41.73% over the last year (+1,229 domains).
? Which intermediate CAs does UniTrust sign from?
We have seen 13 intermediates under UniTrust, the busiest being “SHECA OV TLS RSA CA A1” with 1,540 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.
