Polder Security
Stichting Polder Security (PS) is a non-profit foundation organizing community-driven information security events, education, and engagement in the Netherlands and beyond.
The name draws from the Dutch poldermodel, a tradition of reaching consensus through collaboration. This reflects how we believe the security community works best: together.
What We Do
Polder Security (PS) exists to give back to the information security community. We organize events like BSides Amsterdam, run workshops, CTF competitions, and build bridges between students, professionals, and organizations.
Community Events
From BSides Amsterdam to local meetups, we create spaces where hackers, builders, and defenders come together to share knowledge.
Education & Research
Hands-on workshops, CTF competitions, and published research to advance practical security knowledge across all skill levels.
Talent Development
Mentoring, scholarships, and partnerships with educational institutions to grow the next generation of security professionals.
