DV, OV and EV
DV confirms domain control and is usually enough for simple websites and panels.
OV and EV add organization validation, making them a better fit for business services, B2B and projects requiring formal trust.
Wildcard and multi-domain
Wildcard protects multiple subdomains of one domain, while SAN/multi-domain covers different names with one certificate.
Multi-domain wildcard combines both approaches for projects with many domains and subdomains.
Free SSL and BIMI
ZeroSSL/Sectigo and Let's Encrypt help deploy HTTPS quickly with DV validation.
VMC and CMC support BIMI and brand logo visibility in selected mail services.
