Porto-based and powered by chaos, I split my time between Portugal, Chicago, and wherever the next conference or suspicious packet capture happens to be. Equal parts cybersecurity architect, honeypot wrangler, and frequent flyer with a questionable relationship to gravity, I run a growing Honeypot Empire designed to annoy attackers around the globe!!

When not speaking at security conferences or building deceptive little digital trapdoors for internet goblins, I can usually be found hopping continents, mentoring folks in cybersecurity, sipping dangerously good tequila, or voluntarily jumping out of perfectly functional airplanes. Sasha the Dancing Flamingo still supervises operations with chaotic authority and absolutely believes she deserves root access.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

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.
