Penetration Testing / Reverse Engineering / Vulnerability Research

Based on attack research proven on the international stage, we analyze the essence of threats and
design a proactive security response framework that covers all fronts.

Based on in-depth research by hackers, we identify the latest security threats and design a comprehensive proactive response system.

Penetration testing

The standard for determining whether “our systems are secure” is getting higher every day, and compliance alone makes it difficult to stop advanced threats. We identify the practical limits of the current security framework across a wide range of assets and provide in-depth mitigation strategies. Penetration depends on “who” performs it.

Vulnerabilities inside a system that are not visible on the surface become deadly weapons the moment attackers identify them. We perform reverse engineering that goes beyond bytes and binaries, all the way to circuits, signals, and PUFF. We’ll show you the depth of proven analysis.

Reverse Engineering

We don’t stop at confirming whether a vulnerability exists. We study why it exists, what impact it can have, and how to fix it. Our research is not a “risk alert.” It is “companionship.

Vulnerability Research

The best security is achieved by internalizing strong response capabilities. Beyond simple training, we provide customized drills and educational content based on proven know-how and expertise. We aim for a partnership that shares capabilities proven on the highest stage and grows together.

Where Offensive Research Meets Engineering Discipline

Beyond Pentesting,

Towards Cyber Security Engineering Excellence

We go beyond simple vulnerability assessments, analyzing from the attacker’s perspective from hardware circuits to software logic,
and complete engineering from the defender’s point of view.

Our differentiator is completely breaking down the boundaries between work and research

pure passion for hacking itself, and this is proven by customized in-depth analysis and tangible core security outcomes.

A passion for taking on challenges

We approach every project as a new research challenge, thoroughly analyzing systems from the ground up to uncover customer-specific vulnerabilities that off-the-shelf solutions miss.

Results focused on the essentials

We focus on meaningful vulnerabilities uncovered by digging into core logic, not on formal reports. We carefully identify threats that pose a real risk to your business and provide practical, effective solutions.

Proven technical pride

Our consistent performance at international competitions proves our commitment to hacking. We devote the latest technologies we have built through research and competitions to protecting our customers' assets.
