I think that the Phishing eventscount should focus on number of phishing events per organization. If the phishing event count was decreased after an organization start to use EV certificate, the EV certificate should have some effect to reduce the phishing event. Thanks, Robin Lin >

My understanding of the days before EV was that the CAs themselves made up the validation requirements for DV and because of this there was an uneven validation requirements across the industry. EV was the first document created to solve this and standardise validation requirements for a

Please tell me if I understand this correctly... Is it that DV and EV certificates now both show the same lock symbol? That would be a great harm in my opinion. And I do not understand why you want this change. I think EV is very important and I explain why. Let's look at following hypothetical
