Atos SE announced support through its technological brand Bull for the Microsoft Office 365 suite on any device with Evidian Web Access Manager (WAM), its Web Single Sign-On & Identity Federation solution. Evidian WAM helps organizations move seamlessly to the Cloud and increases the security of access to internal company messages and applications over the internet as well as to external web applications outside the company's premises. This performance is achieved without impacting users. Deploying Office 365 with Evidian WAM is simple and cost-efficient by optimizing provisioning cost and access management. With Evidian Identity Governance and Administration, businesses can manage and keep control of federation mechanisms: Office 365 licenses are provided when users are granted access, and then decommissioned when they lose their rights, thus not only limiting the risk of dormant accounts but also optimizing costs. Combined with Evidian Web Access Manager, users have instant access to their Microsoft Office 365 account using Self-service to request the right to use applications while being offered increased security through adaptive authentication which determines the required strength of the authentication mechanism.
