ZoTrus Technology is the certificate authority for 11 active domains as of October 15, 2026 - 0.00% of every domain DNSniffer can attribute to an issuer.
? Is ZoTrus Technology gaining or losing market share?
The number of domains secured by ZoTrus Technology has grown by 450.00% over the last year (+9 domains).
? Which intermediate CAs does ZoTrus Technology sign from?
We have seen 5 intermediates under ZoTrus Technology, the busiest being “ZoTrus DV SSL CA” with 7 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.
