Report Description |
This report doesn't have that problem, since it doesn't verify the signatures of the certificates it finds, it only uses the issuer Organization Name to uniquely identify the issuing CA.

Note: Readers are cautioned that the Growth percentages are based on
a CA's market share penetration rather than the absolute number of
certificates we detected. Thus, it is possible for the number of certificates
to increase, while the growth is actually a negative value.
