„With over 800 regularly changing officials, we rely on Seamless to automate our guest governance and to keep track of who, why, and where in Microsoft Teams access is granted.”
Marc Rauber, Head ICT Operations & Services SFV

„In just two years with Microsoft Teams, our tenant has welcomed over 1’600 guests. Thanks to Seamless, identifying and removing inactive guests is a breeze!”
Patrick Huber, CIO Amstein + Walthert Group

Without automated guest governance, administrators struggle to identify valid and non-compliant guest access. Seamless automates guest governance and transfers guest responsibilities to your Microsoft Teams users.
Teams users independently invite and oversee guests throughout collaborations, while your company’s governance is automatically enforced for all directory guests.
Administrators configure individual invitation flows that enforce the requirements that need to be fulfilled when Teams users invite guests for collaboration and give access to Teams.
Each guest is assigned to a sponsor. This ensures that the point of contact is always known, making communications and processes straightforward.
Regular renewals ensure that guests are automatically blocked or removed if access is not renewed by the sponsor.
After collaboration ends, guest access can linger, increasing the risk of accidental data sharing. Seamless mitigates this risk with the following features:
Administrators can see all guests and their status at a glance. Invalid, orphaned, or inactive guests, and their access, are cleaned up in no time.
Establish naming policies to maintain order in your Microsoft Entra ID. This simplifies administrative tasks and clarifies differentiation between internal identities and guests.
Daily compliance checks automatically report, block, or delete guests that are outdated, inactive, or do not meet your security and data compliance requirements.

„We do not allow contractors and visitors permanent access to our offices. So why do we still grant guests permanent access to data in Microsoft Teams?”
Michael Wellauer, ICT Operations & Engineering Hirslanden
