We Break Things to Make Them Safer

Clearnet Labs is a security firm founded by former cyber crime investigators. With deep roots in law enforcement and offensive cyber operations, we bring a threat-led mindset to every engagement.

Our team specialises in high-impact testing and secure engineering — from simulated attacks and adversary emulation to helping you build and defend applications the right way. We don't just find vulnerabilities. We show you what it means when someone exploits them.

Ethical Hackers
Building Safer Systems

Founded by former law enforcement specialists, our team brings decades of hands-on experience from real-world cybercrime investigations. We apply that same mindset to proactive security testing, threat simulation, and secure system design for forward-thinking organisations.
