Insights

I'm Eldon Gabriel, an ISC² Certified Cybersecurity Professional with hands-on experience securing and managing Windows and Linux environments through real-world labs, projects, and structured training under the MSAF (System Administration Fundamentals) program. My work focuses on system hardening, network security, troubleshooting, and defensive security operations.

I also completed the Mercor Red Teaming Academy, where I gained experience in AI safety concepts, threat modeling, and practical red-teaming exercises, including a live evaluation-based red team assessment. In addition, I completed an AI dataset training project, which strengthened my attention to detail, analytical thinking, and ability to work with structured technical data.

With 100+ labs and reports completed, I focus on practical skills that support secure IT operations, incident response readiness, and real-world cybersecurity problem solving.
