About

Cyber Security Analyst with experience in vulnerability management, penetration testing, and network security within enterprise environments.I am OSCP certified and enjoy understanding how vulnerabilities are discovered, exploited, and ultimately fixed. Whether it is analyzing new CVEs, assessing web application security, investigating security issues, or improving security processes, I enjoy work that combines technical depth with real-world impact.During my time at Siemens in Munich, I analyzed newly disclosed vulnerabilities, assessed enterprise-wide exposure, and supported remediation efforts by helping teams prioritize risks and make informed security decisions. My background also includes network security engineering experience, including firewall configuration, IDS optimization, log analysis, and zero-trust network segmentation.With a Master’s degree in Cyber Security from HDBW Munich, I focus on identifying realistic attack paths and reducing measurable cyber risk across modern IT infrastructures. I am currently focused on opportunities in Cyber Security, Vulnerability Management, Penetration Testing, and Security Operations, where I can contribute to meaningful security challenges and help organizations reduce cyber risk.📍 Munich, Germany📧 dineshsekar.career@gmail.com
