# faq
? How many domains does Xin Net Technology secure?
Xin Net Technology is the certificate authority for 41,823 active domains as of October 15, 2026 - 0.02% of every domain DNSniffer can attribute to an issuer.
? Is Xin Net Technology gaining or losing market share?
The number of domains secured by Xin Net Technology has grown by 46.30% over the last year (+13,236 domains).
? Which intermediate CAs does Xin Net Technology sign from?
We have seen 7 intermediates under Xin Net Technology, the busiest being “XinNet DV TLS RSA CA 2025” with 39,391 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.
