SEFOS is a web service but is also available as a plugin to MS Outlook and Teams. Send and receive encrypted messages directly from both apps.
With the MS Teams integration, it is also possible to verify users into Teams Meetings by letting the invited recipients use everything from service ID to private eID and SMS.
So if you or your organization is in need of being able to ensure that the right people are participating in your team meetings, get started with SEFOS and you can also send protected messages via the same service!
