Top SchoolEdwin Aybar is a security-focused founder and CEO with eight years of hands-on experience in offensive security, systems architecture, and IT leadership based in the Dominican Republic. He built and runs CyStrong after founding prior security firms and has led penetration testing, risk assessments, and SecDevOps engagements across finance, telecom, and education. Technically fluent across *NIX and Windows server environments, low-level languages (assembly, C), scripting (Python, Ruby, Bash), cloud (AWS) and container/OpenStack platforms, he pairs exploit and reverse-engineering expertise with policy and standards-driven governance (ISO, PCI, NIST). Edwin also trains and mentors others—teaching ethical hacking and GNU/Linux—and has applied frameworks like MITRE ATT&CK, OWASP and NIST 800-115 in real-world assessments. Beyond assessments, he has practical SIEM and Darktrace experience and a Master in Auditing and Information Security, giving him both offensive depth and compliance-oriented perspective. Colleagues describe him as a pragmatic operator who translates complex vulnerabilities into auditable remediation and business-ready controls.
