DigiCert is the world's largest commercial certificate authority by issuance volume and the trust root behind a majority of top-100 enterprise websites. Their certificates are issued from the DigiCert Global Root CA, present in every modern browser, OS, and mobile platform's trust store. DigiCert is the natural choice when "must work everywhere, no compatibility surprises" outranks price.
Organization Validation (OV) — verified identity in the certificate
In addition to domain control, the CA verifies the legal existence and operational status of your organisation against authoritative business registries, plus a phone-call verification to a publicly-listed company number. The resulting certificate's Subject field includes the verified company name and registered address.
Issuance typically takes 1–3 business days while documents are reviewed. The validation result is shown in every browser when a user inspects the certificate, providing a stronger trust signal than DV for business-to-business and commerce sites.
Pick OV when: you operate a registered business and want the certificate to show your verified company name, you process customer payments or sensitive data on the site, you need a trust signal stronger than DV but don't need the full EV process.
Wildcard coverage
Secures a base domain and all first-level subdomains under a single certificate (example.com + *.example.com). One cert covers app.example.com, api.example.com, staging.example.com, and any other first-level subdomain you create — present or future, no re-issue needed.
The right choice when you operate multi-tenant SaaS with customer subdomains (.app.example.com), microservices on subdomains, or any architecture where new subdomains are routine. Note that wildcards cover only one level — .example.com does NOT cover .app.example.com. For multi-level wildcards or arbitrary domain combinations, a Multi-Domain (SAN) certificate is the right fit.
