Well, many certs have something in the O field.

I agree that blindly showing the O field may not be ideal - there *may* conceivably be some CAs that include it without validation on their cheap certs (although most cheap certs simply don't include it). But it's not clear that EV or not is the right criterion here - there are certainly non-EV certs out there that are organisation validated. > You should show the organisation data instead of the domain name if you > find it, for EV certs. I have really mixed feelings about giving this privileged treatment exclusively to EV certs, for the simple reason that the rules around EV certs are iniquitous and some businesses are excluded. e.g. in the UK sole traders (that is, unincorporated businesses) can't get EV certs because the UK doesn't maintain a trade register of such businesses and therefore such businesses are incapable of satisfying the EV rules. That said, EV certs are here, now, and (sadly) supporting them is better than doing nothing... roy ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
