To help users choose the correct identity-based digital certificate, IdenTrust has identified vertical markets that rely on digital certificates to ensure security, privacy and compliance.  These verticals are grouped into Buying Communities that reflect similarities in the use of digital certificates. 

For example, within Buying Communities like Government or Healthcare, there are programs for Relying Parties that host secure DoD websites or Affiliated Parties that offer eHR/eMR software.  These groups require specific digital certificate types to comply with applicable regulations, integrate with a software application or facilitate specific processes for conducting business.  If you are a government employee, a government contractor, a professional working with a government agency or are in the healthcare field, be sure to check out the Government or Healthcare Buying Communities for specific programs with which you are associated.  You will also be able to use our Certificate Selection Wizard to help you choose precisely the certificate you need, based on the Buying Community you select.

Of course, if you need assistance in choosing the best digital certificate for your needs, please contact us directly at [email protected].  We are happy to help!
