Nishant Sharma.

Hello! I'm Nishant Sharma. I build products — and the teams that build them. My track record is starting things from zero: standing up cost-effective, high-performing remote technical organisations, hiring and training them, and pointing them at hard problems.

Over a decade in cybersecurity and product development has convinced me that the best security products come from people who have done the work themselves. I've led world-class research teams, shipped open-source tooling the industry actually uses, and taught thousands of students and professionals across 125+ countries from the stages of DEF CON, Black Hat, HITB and RootCon.

Today I serve as Director, Product Management at Zscaler, working on Zero Trust Browser — the product family that lets people work securely in the browser, whether through the Zscaler browser extension, the purpose-built enterprise browser, or cloud browser isolation. Knowing first-hand how browsers, extensions and AI agents fail is exactly what lets me define what a product has to do about it, and hold a technical bar with the engineers building it.

Previously I was Head of Cybersecurity Research at SquareX (Browser Detection-Response, acquired by Zscaler), VP of Labs, R&D at INE, Head of R&D at Pentester Academy (acquired by INE), and MTS at Mojo Networks (acquired by Arista Networks) — building products, platforms and research programmes from the ground up at each.
