I build the security toolsI wish I’d had.

Fifteen years reading attack surfaces — breaking into banks, then securing them at AWS, now building autonomous defence at RiskProfiler. Every tool I ship is one I wanted as a customer.

00 · THE THESIS

A mountain and an attack surface are read the same way: everything is connected, and the real danger is whatever you haven’t mapped yet. I spend my days on security graphs and my weekends on real mountains and I’ve stopped pretending they’re different problems.

Week one, he broke into the company’s master database account. Then said nothing for two weeks and watched how the organisation behaved — because access was never the interesting part. The report described a system, not a bug.

Led the rebuild of the entire cloud landing zone. Highly secure, heavily automated, and — the part people forget — maintainable by the team that inherited it.

Securing the largest financial institutions in EMEA — HSBC, Barclays, Credit Suisse, Santander, Vodafone. The lesson that stuck: modern infrastructure changes faster than any static security model can describe it.

Product security at the other end of the spectrum from a bank. Seven months — and the last time he would secure someone else’s estate.

Attackers move across boundaries freely; the tools defending against them do not. Unifying external threats — brand, third-party, attack surface — under one security graph was never about licence savings. It was about restoring context. Two people to roughly forty, on about $2M.

02 · CRAFT

What I do best.

Three fortes, sharpened over fifteen years. Everything else is in service of these.

01 / CLOUD
Cloud Security Engineering

Securing cloud estates that change faster than any static model — landing zones, attack surface, detection. Built to be inherited by the team that stays, not just shipped.

02 / COMPANY
Startup CTO & Entrepreneur

Two people to roughly forty on about $2M. First raise, first six-figure customer. Every hat a founder wears — and the judgement to know which ones to keep on.

03 / PRODUCT
Product & Innovation

The last three years turning security research into product — deciding what to build, keeping the innovation honest, and shipping to CISOs who have no time to waste.

CURRENTLY BUILDING

KnyX — autonomous investigations

Twenty-six agents over a unified exposure graph, running the loop a senior analyst runs — and acting where policy allows.

An autonomous system that cannot show its work is not autonomous — it is unaccountable.

Dispatches from exposed terrain.

Essays on agentic security systems, external exposure, and company building. No filler — if it isn’t worth an hour of a CISO’s attention, it doesn’t ship.

I’ve never climbed Kanchenjunga. But whether the mountain is real or metaphorical — when I say I’ll conquer it, believe me, I will.

The door is open.

Currently building autonomous external threat defence at RiskProfiler. Good conversations: security architecture, agentic systems, and company building.
