Ranja A.

About

I am a Cybersecurity Analyst based in Madagascar with nearly three years of experience in vulnerability management, incident response, and penetration testing within a large enterprise telecom environment.

I have led a vulnerability management program covering 1,500+ assets, contributing to the reduction of critical risk exposure across the organization. My experience includes conducting security assessments on 30+ web and mobile applications, identifying high-risk OWASP vulnerabilities, and supporting remediation efforts to reduce external attack surface.

I have also implemented and maintained internal penetration testing labs to standardize testing procedures and strengthen vulnerability discovery capabilities. In parallel, I have investigated and responded to over 100 security incidents, leveraging SIEM, EDR, WAF, and log analysis to detect and mitigate threats.

Beyond technical operations, I collaborate with stakeholders on risk management and national data protection compliance, and actively promote security awareness initiatives.

I am particularly eager to further specialize in penetration testing and advance along the offensive security path, continuously sharpening my skills through hands-on labs, research, and real-world assessments. I remain committed to continuous learning and building practical solutions to address evolving cyber threats.
