What does the Warranty actually mean?

We believe it is important to protect the end user. If we fail to properly validate the information contained in a digital certificate, and our failure causes the end-user to lose money in connection with a fraudulent online credit card transaction, then the end-user may have a claim to recovery under our certificate warranty. (see complete Relying Party Warranty and Agreement for complete details)

We value the end user. We believe the warranty provides peace of mind of the accuracy of the certificate information and therefore helps the merchant to sell more products. Most importantly, we value our validation techniques and are able to offer higher warranty limits than some of our CA competitors. Finally, it is worth pointing out, that we offer high validation, but not at the compromise of speed. You can still obtain SSL instantly.
