About Sunil Kumar

I am a seasoned Cybersecurity Professional specializing in Vulnerability Management, Penetration Testing, and Information Security. With over 5 years of experience, I have developed advanced expertise in vulnerability scanning, reporting, mitigation, and exploitation of security weaknesses. My focus on safeguarding critical systems and ensuring robust security measures makes me an asset to any organization committed to protecting its data and infrastructure. In addition to identifying and remediating vulnerabilities, I bring extensive hands-on experience in API Testing and OWASP Top 10 vulnerabilities. I have successfully conducted penetration tests, including SQL injection and manual testing techniques, to secure applications and networks. Collaborating closely with developer and IT teams, I ensure that vulnerabilities are understood and addressed efficiently, enhancing overall security posture. My background also includes strong proficiency in Active Directory, GPO management, and threat detection modeling, leveraging open-source intelligence and social engineering techniques to identify potential threats. Beyond my role at Infosys, I’ve contributed to IT support and operations at the Financial Services Regulatory Authority of Ontario (FSRA), where I gained valuable experience in infrastructure management and technical support. I hold certifications in CyberArk, ethical hacking, cloud security, and cybersecurity infrastructure. My passion for research is reflected in my published works, covering topics like ransomware, buffer overflow, and zero-day vulnerabilities. If you\'re looking for a cybersecurity professional who thrives on tackling complex security challenges and is passionate about safeguarding your business in today\'s evolving threat landscape, let’s connect!
