We Are the
Shield
Defending the digital frontier with precision, integrity, and relentless vigilance.
Forged in the Dark
RadiumFox began in 2023 not as a corporation, but as a collective. We were a group of 10 friends—elite testers, researchers, and engineers—who had spent years breaking into the systems of the world's largest companies. We shared a common frustration with the industry's "report-mill" mentality and a shared passion for the art of exploitation. We knew we could do it better, deeper, and with more impact.
By 2025, that collective evolved into RadiumFox. Based in the tech heart of Austin, Texas, we have grown from a circle of friends into a global force in offensive security. While our roots are deep in the Texas hill country, our reach is worldwide. We bring our Austin-born tenacity and innovation to clients across every continent, securing critical infrastructure, financial systems, and Fortune 500 networks.
This isn't just a job for us; it's our obsession. Our team is composed of the same experts who have tested the security of the biggest names in tech. We don't hide behind junior testers or automated tools. When you hire RadiumFox, you get the founders, the architects, and the experts who built this company on a foundation of friendship and relentless curiosity.
"From a garage in Austin to the global stage, our mission hasn't changed: We break it so they can't."
We are proud to call Austin home, but we are ready to deploy anywhere. Whether you are a local startup or a multinational enterprise, we bring the same level of intensity and expertise to every engagement. We are RadiumFox.
We protect organizations through Integrity, unwavering Vigilance, and surgical Precision. Our mission is to expose vulnerabilities before adversaries do.
Our Values
The principles that guide every decision we make.
Uncompromising Integrity
We operate in the shadows, but our ethics are black and white. We believe that trust is the currency of security. Whether we are handling sensitive patient data or critical infrastructure schematics, we treat your secrets with the same reverence as our own. We report what we find, without sugarcoating, because true security requires facing uncomfortable truths.
Surgical Precision
We reject the 'spray and pray' approach of automated scanners. Our methodologies are surgical, targeting real-world attack vectors with the precision of a nation-state actor. We don't just find vulnerabilities; we demonstrate impact. We show you exactly how a flaw can be weaponized to steal data, disrupt operations, or compromise your brand.
Adversarial Collaboration
We are not just testers; we are partners in your defense. We believe in 'Purple Teaming'—working side-by-side with your internal security teams to transfer knowledge. When we break in, we show you how we did it, and we stay until you understand how to stop us next time. Your resilience is our only metric of success.
Relentless Innovation
The threat landscape changes every hour. Yesterday's defenses are today's vulnerabilities. That's why we invest 20% of our revenue back into R&D. We develop our own exploits, build our own tools, and constantly evolve our tradecraft to stay ahead of the adversaries targeting you. We don't follow best practices; we define them.
Global Threat Intelligence
Our decentralized security grid monitors millions of events per second, neutralizing threats before they reach your infrastructure.
