Founder

Andres Marten

With more than two decades of experience in technology and cybersecurity, Andres Marten has established himself as a recognized leader in cyber intelligence, threat hunting, incident response, and strategic security leadership. His background combines deep technical expertise with a strong business-oriented executive perspective, enabling him to advise complex organizations operating in some of the most challenging and sophisticated threat environments in the region.

Before founding APT Zero, Andres built a distinguished career at IBM, where he spent more than a decade serving in senior security consulting and regional leadership roles across Latin America. As part of that trajectory, he worked for three years in the United States, operating directly from the corporate offices of a strategic client as well as IBM's primary Security Operations Center (SOC) in Atlanta, contributing to high-criticality security operations and investigations within large-scale enterprise environments.

Throughout his career at IBM, Andres led multidisciplinary teams responsible for advanced investigations, cyber defense initiatives, and strategic security programs for Fortune 500 organizations and major multinational enterprises. He also served as a trusted technical escalation point and strategic advisor for high-severity incidents, including complex cyber investigations, advanced persistent threats (APT), and response operations within highly sensitive environments.

His work has consistently focused on helping organizations strengthen security maturity through enhanced detection and response capabilities, improved threat visibility, optimized security operations, and cybersecurity strategies aligned with business objectives. His ability to translate highly technical findings into clear, actionable executive decisions has allowed him to work effectively with both technical teams and senior leadership.

Andres combines hands-on operational experience, corporate leadership, and a strong academic and professional background. He holds a Bachelor's degree in Computer Science and maintains a portfolio of industry-recognized certifications including CISSP, CISM, CEH, and CySa+. Complementing his cybersecurity expertise, he has also completed advanced studies in artificial intelligence at The University of Texas at Austin, earning both the Artificial Intelligence for Leaders certificate and the Postgraduate Program in Artificial Intelligence and Automation.

This uncommon combination of advanced cybersecurity expertise, executive perspective, and artificial intelligence specialization reflects the broader vision behind APT Zero: a modern cybersecurity firm built to deliver technically rigorous, strategically informed security leadership aligned with real business needs.

Today, Andres works with organizations seeking far more than a traditional security provider — they seek a strategic partner with real-world experience in high-pressure environments, capable of anticipating threats, responding with precision, and strengthening long-term organizational resilience.

Our Philosophy

Cybersecurity should do more than protect systems.

It should help organizations make better decisions.

It should strengthen resilience.

It should reduce uncertainty.

It should give leaders greater confidence in how risk is understood, communicated, and managed.

Our approach is built on the idea that effective cybersecurity is not about creating noise or complexity for its own sake. It is about identifying what truly matters, focusing on material risk, and delivering guidance that is clear, practical, and aligned with the realities of the business.

We work with a calm, disciplined, and intelligence-led mindset. That means combining technical rigor with strategic judgment, and always keeping the client's broader operational and business context in view.

Why APT Zero

The name behind the mission.

APT — Advanced Persistent Threat

In cybersecurity, APT stands for Advanced Persistent Threat: a sophisticated, well-resourced adversary capable of gaining and maintaining stealthy access to an environment over time, often with the objective of espionage, disruption, or long-term compromise. These threats represent the kind of risk that cannot be addressed through superficial controls alone.

Zero — Our Mission

Zero represents our mission: to help organizations reduce serious threats, critical exposures, and preventable cyber risk as close to zero as possible. It is not a promise of perfection. It is a commitment to disciplined risk reduction, intelligent prioritization, and continuous improvement.

APT Zero was built for organizations that value trusted expertise, meaningful outcomes, and a more refined advisory experience. We exist to provide a higher standard of cybersecurity support: one defined by precision, discretion, and strategic clarity.
