About Me

Profile

I’m Nirwan Geeth Kaweeshwara, a passionate cybersecurity professional focused on ethical hacking and penetration testing. My primary goal is to help individuals, businesses, and organizations identify and fix security vulnerabilities before they can be exploited by malicious actors. I specialize in real-world penetration testing across networks, web applications, and systems, simulating advanced attack techniques to uncover weaknesses and provide clear, actionable solutions.

Over the years, I’ve developed and used custom tools to enhance testing efficiency, and I always stay updated with the latest threats, exploits, and techniques. Whether it's analyzing open ports, testing web app security, or detecting unpatched systems, I approach every project with attention to detail and a strong understanding of how attackers think.

My work reflects a strong commitment to cybersecurity, privacy, and the ethical use of hacking skills. I also enjoy building browser extensions and tools that improve online security for users. Through my services, I aim to strengthen defenses and raise awareness of digital risks in a constantly evolving cyber landscape.

If you're looking for a reliable, knowledgeable penetration tester to secure your digital assets, you're in the right place.
