I’m VETTRIVEL U, a passionate Offensive Security Expert hailing from Cuddalore, Tamil Nadu, India 🇮🇳.
I'm specialized in Vulnerability Assessment & Penetration Testing (VAPT), Red Teaming, and Offensive Security Operations — with a proven track record of breaching systems to secure them.
I’ve earned multiple Hall of Fame recognitions from MNCs for responsibly disclosing critical vulnerabilities. From gaining root access to high-level systems to pwning servers, I’ve had the thrill of ethically exploiting and helping secure both Indian and US government infrastructures.
Along the way, I’ve bagged exclusive swags and rewards, and I’m proudly listed as a Top Voice in Information Security on LinkedIn.
As a freelancer, I collaborate with companies to work on outsourced security projects — and have been paid by top-tier organizations for my findings.
I also love giving back to the community: conducting classes, webinars, and mentorship sessions for juniors and aspiring bug bounty hunters.
I recently qualified for the finals of a national-level Hackathon x CTF, proving my ability to think under pressure and hack smart.
