Cybersecurity Consulting
APT Zero is a boutique cybersecurity consulting firm founded by Andrés Martén. We help organizations identify, prioritize, monitor, and reduce cyber risk through expert guidance, technical assessments, and strategic advisory services.
Cybersecurity consulting is the foundation of a resilient security program. Rather than deploying technology and hoping for the best, organizations that engage with experienced consultants gain clarity on where they are exposed, what to prioritize, and how to strengthen their defenses in a practical, cost-effective way.
At APT Zero, our cybersecurity consulting engagements are designed to deliver meaningful outcomes — not lengthy reports that sit unread. We work directly with your leadership team and technical staff to understand your business context, identify the risks that matter most, and build a clear path forward.
Our consulting approach combines technical rigor with executive-level communication. We translate complex security findings into decisions your leadership can understand and act on. Whether you need a one-time assessment, an ongoing advisory relationship, or help preparing for an audit, APT Zero brings the experience and discipline to support your goals.
Services within our cybersecurity consulting practice include cybersecurity assessments, risk assessments, vCISO (virtual Chief Information Security Officer) engagements, governance and compliance advisory, incident readiness reviews, Microsoft 365 and cloud security reviews, privileged access reviews, and executive cyber advisory services.
Organizations that invest in cybersecurity consulting gain more than recommendations — they gain a strategic partner capable of helping them make better security decisions over time. APT Zero is that partner.
