Ilex IAM Platform is a French identity and access management suite from Ilex International in Clichy, offered under the Nexpublica name. The suite has four parts: Access Management (Sign&go) with web, enterprise and mobile SSO, multi-factor authentication, federation and self-service password reset; Identity Management for lifecycle, rights review and provisioning; a Credential Management System for authentication devices such as cards; and Customer IAM for external users such as customers, subscribers or citizens. According to the vendor, the suite runs on-premise or in your own private cloud, or as SaaS.
Ilex and Nexpublica are based in Clichy, France; the website states that development takes place in France and names no foreign owner. The SaaS offer is described as sovereign and prepared for the French SecNumCloud framework, with no hosting provider or data centre location named, so ask the vendor. With the on-premise and private-cloud variants you decide where the data is kept. No open-source licence is mentioned, and the pages reviewed carry no GDPR statement for the product, so ask for data processing terms.
