Phishiest Certificate Authorities

This table show the top 10 phishiest certificate authorities, based on the number of currently blocked phishing sites with an associated valid, trusted SSL certificate where the CA has had a chance to review the deceptive domain name or host name. For example, we do not include a block of borclays.netcraft.com as the associated certificate is valid for *.netcraft.com.
