I break into things for a living. Legally.

I'm Krishna Agarwal, from Gwalior, India. Technology never felt like a choice. It chose me at seventeen, back when I was a script kiddie with far more curiosity than skill. I never really stopped, and what started as poking at things to see how they broke became the way I think about everything.

I work for myself, and I intend to keep it that way. I've never done my best work under someone else's pressure, so I'm building my own thing instead, and doing my part for a field I care about.

Principle Breach isn't a typical security consultancy. It's closer to a research and analysis shop: we go after the things that are supposed to be unbreakable, and we break them.

The premise is simple, and unfashionable. All software is vulnerable, but most of the industry runs as if that weren't true. Compliance checklists, dashboards, and scanner output make people feel secure without making them secure. Most of what passes for security is theater. I'm interested in the part that isn't.

Most of my time is hands-on: penetration tests and red team engagements for teams that want to see how a real attacker would get in, and independent vulnerability research the rest of the time. I've reported more bugs, to more organizations, than I can keep track of. I don't keep a trophy wall, though. The finding always mattered less to me than the fact that it was sitting there to be found, and someone with worse intentions would have found it first.

The writeups I'm allowed to publish end up on the blog.

Lately most of my building energy goes into AI. Offensive security is turning into AI-and-humans against AI-and-humans, and I'd rather be early than surprised, so I build offensive AI tooling for my own research: some of it inside Principle Breach, some as a weekend obsession. I have plenty of opinions about where the industry gets pentesting, bug bounties, and AI wrong, but those belong on the blog, not here.

Away from the terminal I read a lot: philosophy, history, psychology, whatever is pulling at me. Stoicism and Vedanta have shaped how I think more than any classroom did. Most of my writing starts by hand, in a notebook, before it reaches a screen.

I don't post much on social media. I'd rather leave the work and the reasoning somewhere you can actually sit with them.
