Sectigo (formerly Comodo CA, rebranded 2018) is one of the most widely-issued commercial CA roots on the internet, with strong native browser compatibility and one of the broadest cert portfolios available. The PositiveSSL/EssentialSSL/InstantSSL legacy product lines are particularly popular for hosters and agencies serving SMB customers — solid trust signals at competitive pricing.
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.
Single Domain coverage
Secures one fully-qualified domain (FQDN), with the www. and apex variants both covered as a convention (example.com + www.example.com share one cert). Other subdomains (e.g. app.example.com, api.example.com) require their own certificates.
The simplest and most common coverage type. Choose Single Domain when you have one canonical site, or when the additional subdomains you operate are best served by their own scoped certificates rather than a shared wildcard.
