# faq
? How many domains does Redis secure?
Redis is the certificate authority for 38 active domains as of October 14, 2026 - 0.00% of every domain DNSniffer can attribute to an issuer.
? Is Redis gaining or losing market share?
The number of domains secured by Redis has shrunk by 11.63% over the last year (-5 domains).
? Which intermediate CAs does Redis sign from?
We have seen 2 intermediates under Redis, the busiest being “GlobalSign Atlas R3 OV TLS CA 2025 Q4” with 20 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.
