# faq
? How many domains does TrustAsia Technologies secure?
TrustAsia Technologies is the certificate authority for 942,997 active domains as of October 14, 2026 - 0.40% of every domain DNSniffer can attribute to an issuer.
? Is TrustAsia Technologies gaining or losing market share?
The number of domains secured by TrustAsia Technologies has grown by 158.81% over the last year (+578,635 domains).
? Which intermediate CAs does TrustAsia Technologies sign from?
We have seen 22 intermediates under TrustAsia Technologies, the busiest being “LiteSSL RSA CA 2025” with 549,574 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.
