Frequently Asked Questions

Our trust store is regularly updated to include newly trusted CAs and remove revoked or untrusted ones. It mirrors the trust stores maintained by major browsers and operating systems.

If a CA is not in the trust store, certificates issued by it will trigger browser warnings. You should either obtain a certificate from a trusted CA or manually add the CA to your trust store if it is an internal/private CA.

Trust stores are updated through operating system updates, browser updates, or by manually importing CA certificates. On Linux, use update-ca-certificates; on Windows, manage via the Certificate Manager.
