Guest Access Control (GAC)
de EMRIS, spol. s r.o.
Grant, manage and review the guest access easily.
Guest Access Control will give you the option to maintain your M365 environment secured, and will open gates to guest domains only if it gets approved by your delegated employees. Furthermore you can easily track (audit) who has the access from what company, for how long, who has requested and approved it and the justification for it.
This application will add the Guest automatically to your Azure AD once approved, send him your customized invitation message, will notify the requester that the access was granted and will log everything to SharePoint List. Also it will whitelist the domain for SFB/Teams federation and SharePoint Online.
This service is available for plans M365 Business Basic (formerly O365 Business Essentials) and higher and can be localized in Czech/English both for implementation and support.
