2019: A Hand-Typed Dataset That Changed Everything
KC7 started in 2019 with nothing more than a hunch and a hand-typed dataset. Our founder, Simeon, remembered how playing a simple game in college made learning feel exciting — and wondered if cybersecurity could be taught the same way.
So he built a tiny experiment: a dataset typed out line by line and shared with a community college class. The students dove in, connected the dots, and came away asking for more. That moment — small and scrappy — planted the seed for KC7.
It also revealed something bigger. Too many people never got the chance to experience cybersecurity in a way that showed them what they were capable of. We knew if the right doors opened, people from all kinds of backgrounds could discover their hidden superpower.

From Data to Detective Stories
The experiment didn't stop. The dataset kept growing, and stories began to form around it. What started as raw logs turned into mysteries with characters, clues, and digital breadcrumbs to follow. Players weren't just studying cybersecurity anymore — they were detectives, piecing together intrusions and learning to think like defenders.
Almost by accident, KC7 also created one of the world's richest datasets for cybersecurity investigations — a resource now powering games, training, and research far beyond the classroom.
From Experiment to Nonprofit
By 2023, it was clear this was bigger than one person. Simeon was joined by Greg, Emily, and others who believed in the vision. We had no money and no clear roadmap — just the belief that cybersecurity education could be different. What happened next changed everything: our friends in the cyber industry showed up.
They offered their support, their time, their networks, and yes, even their money to help us build what seemed impossible. Their generosity made it clear that this wasn't just our dream — it was a shared one. It gave us hope that the future of cybersecurity could be more open, more inclusive, and more human than we ever imagined.
Together, we established KC7 as a nonprofit, dedicated to making investigative cybersecurity accessible to anyone, anywhere.

The Movement We're Building
Today, what began as a single hand-typed dataset has grown into a global platform. KC7 is now carried forward by a community of teachers, students, professionals, and volunteers across the world.
We believe cybersecurity is stronger when more people are included. That's why KC7 exists: to help anyone, from any background, step into the role of a defender, solve mysteries, and discover the investigative superpower inside them.
And this is just the beginning.
