Mike van der Bijl

Mike van der Bijl

My career has taken me through a diverse journey, spanning roles that include full-stack developer, business analyst, IT manager, and now thriving in cybersecurity. Throughout this journey, my deep passion for technology has remained a constant driving force.

For me, security resembles solving a 10,000-piece puzzle that's been turned upside down. You understand the end goal, yet you're uncertain about where each piece belongs. Achieving this requires close collaboration with developers, business stakeholders, and others, necessitating me to consistently bridge different disciplines within technology. Whether it's simplifying intricate development concepts for security and business professionals or vice versa, every piece added brings us nearer to the solution. This challenge deeply motivates me.

I approach my work with a clear focus on prioritizing people first, followed by refining processes, and then utilizing technology to enhance these efforts. This philosophy ensures that technological changes are seamlessly integrated and readily embraced by our teams and organizations.

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.
