I teach students to think like hackers, so they build like defenders.

Live ethical hacking demos, penetration testing workshops and on-site hackathon mentorship for engineering colleges across Chennai and Tamil Nadu. No slides-only lectures. Real systems, real exploits, real defence.

Into the real world.

Cybersecurity workshops and ethical hacking seminars delivered at engineering colleges, built around one idea: students learn security fastest when they see how attackers actually think, with ethics and responsible disclosure at the centre.

Hi, I'm Krish 👋
About

Gokula Krishnan

Krish · krishxlabs

I run hands-on cybersecurity workshops and ethical hacking seminars, and mentor hackathon teams across engineering colleges in Chennai and Tamil Nadu. The goal isn't to hack for shock value. It's to show how attackers think, so the next generation of developers builds systems that hold up.

From live exploitation demos in a seminar hall to debugging with a team at 3 AM, I teach the way I learned: by doing it for real.

Krish also owns Kentaurx ↗, his web & AI company.

For colleges

Got questions?

Who are the sessions for?

Engineering students across years and departments, especially CSE, IT and cybersecurity, plus student clubs and developer communities.

How long is a session?

Seminars typically run for two hours. Hackathon mentorship covers the full event, on-site with your team.

Is live hacking safe and ethical?

Yes. Every session centres on ethical boundaries and responsible disclosure. The aim is to teach students to think like attackers so they can build stronger systems, never to cause harm.

What do we need to arrange?

A hall or lab with a projector and a stable internet connection. We'll confirm the details on a quick call.

Can you mentor our hackathon team?

Yes. Reach out with the event details and dates, and we'll plan the mentorship together.
