EV SSL Case Studies

VeriSign has compiled a list of case studies showing how EV SSL has helped various sites. If you need help convincing your superiors to switch to EV SSL, these may be the ticket. VeriSign's Tim Callan said this about the case studies:

As you may know, lots of online businesses have measured the results of putting Extended Validation SSL on their sites and have universally found that it increases the propensity for site visitors to complete sensitive transactions. With so many measurements of EV's effect (I am aware of seventeen such tests, personally), we have decided to gather as many of them together in one place so that it's easy to take in the science all at once.

The case studies cover all kinds of companies including Charles Schwab & Co., Inc., DebtHelp.com, Overstock.com, Fitness Footwear, and Papercheck. Click here to view the EV SSL Case Studies.

I will also post new success stories about EV SSL Certificates here.

That's true. Where are the case studies showing that EV certificates don't work. I agree that case studies published by VeriSign (probably the company that will benefit the most from EV SSL adoption) are bound to be biased. But I am also unable to find case studies about how EV certs don't work. So either EV certificate really do work, or the people who have tested them and know that they don't work aren't sharing.


Thanks for the link. That paper was posted on SSL Shopper here: http://www.sslshopper.com/a...

The problem is that the research occurred before a handful of sites even used EV certificates. It would be interesting to see the results now that thousands of sites are using EV and a large majority of users have an EV-enabled browser.


If I need help convincing read a bunch of Verisign spin on the topic... yay! ;)

Seriously where are the case studies showing how it didn't help, or how it even harmed business, maybe I'm just getting cynical in my old age ;)


Those that know they don't have any advantage, or don't work simply don't bother spending money writing reports trying to convince people one way or the other, after all they wouldn't have much of a financial incentive, the only ones that do are the ones selling them ;)

Hello all,

First, let me point out that I am a marketing analyst for VeriSign and I can help quiet the nay-sayers regarding our EV uplift case studies.

I have been working here for the past 8 months reaching out to customers in attempts to gather EV success metrics: decreases in cart abandonment (Overstock.com), increases in form completions (DebtHelp.com), and increases in sales (Scribendi.com). After months of research, we have compiled 17 uplift metrics ranging from 5-87%.

Not ONCE has a customer returned to me with measured failure.

Now, you can call me names, shake your head, and remain pessimistic. Or you can form an educated decision based on hard data to choose the appropriate solution for your business.

These case studies are quite compelling...even for the cynics ;)

Please feel free to contact me if you have any further questions regarding VeriSign and Extended Validation SSL.

Seems people have written papers on it...


Should I form a similar 'well educated' opinion over microsoft funded case studies too.

You can tout all the figures you want, you can tout all the rhetoric 'nay sayers' you want as well, however it doesn't change a thing about what SSL is and what was claimed about SSL in the past and how we're trying to do better this time round.

How hum, call me a nay sayer, hell print me a shirt and I'll wear it proudly, I nay say Verisign's marketing of EV certificates because it's just more snake oil to convince everyone to part with more of their hard earned cash and give it more freely to Verisign.

Let me know where I can pick my shirt up ;)


While I agree that some of the VeriSign representative's rhetoric is flawed, he still brings up a good point. Where is your evidence that EV certificates don't work? Until you have sufficient evidence, you don't have a good argument. VeriSign is undoubtedly very interested in maintaining the reputation of EV certificates for financial reasons but that doesn't mean that they don't work. And don't forget that it is more than VeriSign pushing EV certificates.

By the way, here your T-shirt: http://www.zazzle.com/naysa...
