Founder & Principal Consultant, Orvantis Security

Orvantis Security is a founder-led offensive-security practice. As founder and principal consultant, I personally scope, deliver and report on every engagement — so the person you speak with first is the same person doing the work, with no hand-offs and no layers between you and the results.

My route into offensive security runs through the other side of the keyboard: I hold a BSc in Software Development (KCA University), so I learned how systems are built before I learned how they fall. That builder's eye is my edge — I know the shortcuts and assumptions developers make, because I've made them, and I know exactly where they break. Attacker mindset starts with a builder's mind.

I founded Orvantis on a simple observation: most organisations only discover how weak their defenses are after someone with bad intentions already has. I help close that gap — bringing hands-on red-team and offensive experience to your systems before an attacker gets there first.

Every engagement is led by the same offensive mindset — measured, careful, and focused on proof over speculation. I don't run an automated scan and present it as a penetration test, and I don't inflate findings to pad a report. If something is broken, I show you exactly how — and exactly how to fix it.

What sharpens that edge is how I work with AI. Think like the attacker, strike at machine speed, prove it by hand. Frontier AI and purpose-built agents hunt your defenses like a real adversary — finding the foothold, chaining weaknesses, and pushing toward your crown jewels. Then a human takes the trigger: I run the attack to the end, prove the breach, and strip the noise down to what truly puts you at risk. Machine speed to find it. Human proof it's real.

The idea

Attacker mindset. Defender mission.

I work with the discipline and creativity of an attacker, and the accountability of a defender. That means testing without cutting corners, reporting without inflating severity, and staying engaged until a finding is actually resolved — not just acknowledged.

I break in on your terms — before someone does on theirs.

How I work

Principles that don't flex per engagement

01 / MINIMAL IMPACT

Prove it. Don't weaponise it.

I demonstrate that a vulnerability exists — I don't turn it into a real-world incident. Exploitation is controlled, contained, and agreed before it happens.

02 / CLIENT-FIRST

Your findings are yours.

What I find on your systems goes to you, privately, with the technical detail you need to fix it — and it stays between us. No surprises, no leverage, no public write-ups of your environment.

03 / EVIDENCE OVER NOISE

Every finding is reproducible.

If I can't reproduce it, I don't report it. Every finding has a proof-of-concept, a business-impact statement, and exact steps — not a scanner alert and a CVSS score.
