Wildcard certificates secure a single domain and all its subdomains. This eliminates the need for separate certificates for each subdomain, making them convenient for organizations with a significant online presence.

Multi-Domain SSL certificates (MDC), or Subject Alternative Name (SAN) certificates, allow for securing multiple domains with a single certificate. This flexibility is ideal for businesses managing several websites or communication platforms.

The time it takes to obtain each certificate depends on the validation process. DV SSL certificates can be acquired in minutes, while OV SSL and EV SSL certificates may take a few days to a few weeks due to the additional verification steps involved.
