Securing the software that powers the world
ABOUT US
Our story
SecureFlag was founded by two security experts who saw the same pattern repeat:
the security industry invested heavily in finding problems, but far less in addressing why those problems kept happening.
They set out to help developers build
secure software from the start by embedding threat modeling and secure design into everyday development—including AI-assisted workflows.
The challenge
The insight was simple but uncomfortable: security wasn't failing because teams didn't care—it was failing because the system made secure behavior difficult to sustain, especially as software development continues to accelerate with AI.
The solution
SecureFlag was built to change that with training that fits real workflows. Developers learn in live, virtualized environments where they identify risks, model threats, and fix vulnerabilities using the same tools and technologies they use every day—including modern IDEs, pipelines, and AI coding assistants. It's hands-on, practical, and intentionally engaging—gamification introduces healthy competition through points and awards, driving participation without forcing it.
Growing through developers
That's what made SecureFlag different early on, and why the developer community became its strongest growth engine. More importantly, that adoption became the foundation for something bigger: an enterprise-ready approach to reducing development risk at scale.
Today
Today, security leaders use SecureFlag to embed threat modeling, secure coding, and developer enablement into the SDLC—driving consistent secure-by-design practices, measuring outcomes, and producing audit-ready evidence, all without slowing delivery in AI-driven development environments.
our vision
Secure coding training should do more than transfer
knowledge—it should change how developers work
That means training built around real development environments,
embedding security requirements and threat modeling, not generic content.
Experiences that adapt to each developer's skill level, stack, role, and use of
AI coding assistants. And outcomes that show up in the code they ship,
not just on a completion report.
our values
Built on purpose
The principles that guide how we build products, work with customers, and help organizations create secure software.
Build for how teams actually work
Security only scales when it fits real workflows. We design SecureFlag to integrate into the tools engineers already use—not force new ones.
Make prevention measurable
Security investment should be defensible. We focus on outcomes—fewer vulnerabilities, faster remediation, and audit‑ready proof—so leaders can see real impact.
Earn trust through consistency
Enterprise teams rely on repeatability. From training outcomes to threat models and reporting, consistency is built into everything we deliver.
Stay practitioner-led
We build with security and engineering teams, not around them. Product decisions are driven by real-world constraints, not theory.
