Florian Salzmann

Florian Salzmann

Florian Salzmann is a Microsoft MVP and Leading Expert at UMB, based in Switzerland. He focuses on modern endpoint management, security, and automation across Microsoft Intune, Windows 365, and the Microsoft Security stack.

He helps organizations fix real-world gaps that cannot be solved through the portal alone. From PowerShell-driven Intune automation and third-party patching to building scalable solutions using Microsoft Graph and custom workflows. A key part of his work is making Intune do things Microsoft hasn’t built yet.

Florian is a regular speaker at international conferences such as MEM Summit Paris, NIC Summit Oslo, and multiple Workplace Ninja events. His sessions are highly technical, demo-driven, and focused on real-world scenarios that attendees can apply immediately, including limitations, pitfalls, and things that don’t work as expected.

Beyond the stage, he shares practical solutions and deep dives on his blog scloud.work, contributes to msnugget.com, and builds reusable automation and tooling for the community. If it involves endpoint management, security, or pushing Intune beyond its limits, he is probably already working on it.

Most Active Speakers 2025

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2025. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
