I already have digital certificate from another vendor. Can I use it instead of buying Exostars FIS certificates to access my application(s)?
If you already have digital certificates from another vendor, you will not be able to use them to access applications via Exostar Managed Access Gateway (MAG). To be able to access your applications, you will be required to get Exostar FIS certificates for the appropriate assurance level. Contact your project partner for detailed information on the assurance level of the certificates.
