Breaking things
so they don't break you.

I'm Nikhil Nair, with 5+ years in offensive security, penetration testing, vulnerability research, and red teaming. I specialize in finding the vulnerabilities that matter: the ones attackers would actually chain into real-world impact.

My research has been recognized by 100+ organizations including Adobe, LG, Intuit, Ericsson, and the U.S. Department of State. Outside client work, I hunt bugs on HackerOne and Bugcrowd, and solve CTFs to stay sharp.

Penetration Testing Services
Your next breach, found by me, not them.

From web apps and APIs to mobile platforms and cloud infrastructure, I find and validate real risk before attackers do, with detailed reports your engineering team can actually act on.

Red Teaming

Most breaches start at the application layer. I dig deep into the logic, not just the checklist, hunting for the vulnerabilities scanners miss and attackers don't.

Web Application Pentest
API Pentest
Mobile Application Pentest
AI and LLM Application Pentest

Cloud sprawl and network complexity hide more risk than most teams realize. I map your real exposure: misconfigs, weak segmentation, lateral paths, before someone else does.

Internal Network Pentest
External Network Pentest
Cloud Pentest
Cloud Configuration Review

Compliance audits don't scare real attackers. I simulate them, chaining techniques across your environment to find what detection would miss and defenders wouldn't expect.
