Yes, we also offer Class 3 certificates, but we deliberately do not offer them. Read on to find out why:
The classification of SSL certificates describes the respective validation and authentication procedures. However, the classes are not standardized in any form, each certificate authority can determine how it classifies them.
Even though the term Class 3 has already established itself as a sort of standard, we prefer the direct naming of the two currently only distinguishable procedures in SSL certification, domain certification and identity certification. Further information can be found here.
For reference, the most common classification currently used for SSL Certificates is as follows:
Class 0: Test certificates without validation (corresponds to self-issued certificates and test certificates from Thawte, test certificates from Psoft and RapidSSL are domain-certified, test certificates from Comodo are identity-certified)
Class 1: Domain certificates validated by telephone and/or e-mail robots (corresponds to our concept of domain certification)
Class 2: Limited Certificates of Identity, based on written confirmation that the information provided is accurate. Are generally not offered as SSL or server certificates, as they offer too little scope for verification, but are regularly used as S/MIME or client employee certificates. After a company and often also its certificate administrator Class 3 have been validated separately, it issues certificates to employees in the company whose identity is personally known or has been confirmed in writing. Such certificates issued internally after a Class 3 validation are considered as Class 2 certificates.
Class 3: Identity certificates validated by checking the data in the commercial register excerpt for companies entered in the commercial register, the trade licence for companies not entered in the commercial register or the identity card for pure private individuals and comparing their data with the data in the WHOIS (corresponds to our concept of identity certification).
Class 4: Extended identity certificates that have been validated by direct face-to-face identification using the original documents and the data in the WHOIS analogous to Class 3 (nowhere offered because too expensive and too time-consuming for both sides).
