ANOIGO (https://www.anoigo.nl/) is our partner in Identity Management. Together with Anoigo we have been able to implement complex identity workflows like the Dutch National Digital Identity DigiD (https://www.digid.nl/) in document workflows generated with for example QUADIENT Inspire.
ANOIGO allows us to implement and integrate with almost every standard authentication protocol, including advanced options like SSO using SAML2 or OAuth.
