Any contact details is visible only for Organization Validation (OV) or Extended Validation (EV) certificates And these certificates require business validation. The PositiveSSL certificate requires completing domain control validation and that is all. The certificate information will contain only the name of the certificate and Certificate Authority, which is PositiveSSL and Sectigo. If yes, then you need to consider buying OV or EV SSL: OV: https://www.namecheap.com/security/ssl-certificates/organization-validation/ EV: https://www.namecheap.com/security/ssl-certificates/extended-validation/ Such SSL certificates will require paperwork and your company being listed in online business directory such Dun&Bradstreet and governmental database. You have a PositiveSSL domain validation certificate (DV) Perfect for blogs, personal websites, and apps. It does not verify the site owner information and is not showing any company details in it whatsoever. Just a simple solution for making HTTPS.
