Here you can find some basic information about our certificates regarding type, validation & duration.
ZeroSSL offers Domain Validation (DV) certificates.
At the moment we do not offer Organization Validation (OV) or Extended Validation (EV), because we would have to vet identity information. DV SSL Certificates are fully supported and come with the advantage of being issued almost immediately and without the need to submit company paperwork. This makes DV SSL ideal for businesses needing low-cost SSL quickly and without much effort.
