YellowHat 2025: Microsoft Security’s New Global Spotlight
YellowHat 2025 made waves as a fresh, community-driven event focused entirely on Microsoft Security. Held on March 6th at Microsoft’s Amsterdam HQ, it attracted over 150 attendees in person and 1,500 online worldwide. The goal? To deliver deep, technical insights at a level 400+—perfect for security pros hungry for advanced knowledge.
What’s New: A Community-Powered Security Event
Unlike traditional conferences, YellowHat was created by the community, for the community. Myron Helgering, one of the organizers, explained their motivation: “We felt there was a need for something new: an event organized by and for the community, focused solely on Microsoft Security content.” This fresh approach gave the event a unique vibe, emphasizing hands-on, practical security strategies.
“Wear your yellow hat to prevent cyber threats.”
The name itself draws from the protective yellow hard hats worn by construction workers, symbolizing defenders in the cybersecurity world.
Major Updates: Hybrid Format and Top-Tier Speakers
The hybrid format was a game changer. It balanced in-person networking with engaging online experiences, including live interviews and sponsor showcases during breaks. This approach ensured no attendee missed out, regardless of location.
YellowHat’s lineup was another highlight. Speakers like Raviv Tamir, Roberto Rodriguez, and Dirk-Jan Mollema brought visionary insights. According to Myron, “We selected our speakers based on their expertise, experience, and their ability to deliver engaging and relevant content.” This careful curation made the technical sessions both cohesive and immediately applicable.
Global Reach Through Community Power
The event leveraged the Dutch Microsoft Security Meetup’s 2,000+ members and international MVPs to spread the word. Even the event’s mascot, Ninja Cat with a yellow hard hat, became a social media star, boosting visibility.
