I build security infrastructure for AI agents.

I’m Gustavo Aragón, founder of Oktsec. Cybersecurity was one of the first disciplines I worked in. Across more than 20 years, I expanded into product, fintech and regulated technology without leaving security behind.

At Brelo in Brazil, security was central to the device-locking technology we built and patented. Recurring jailbreak attempts made hardening, permissions and operational controls product requirements. I bring that same builder’s discipline to AI agents, MCP, automation and software supply chains.

A security practice built over decades.

01

Security from the start

Cybersecurity was one of the first areas I worked in. It shaped how I think about systems long before Oktsec and the current generation of AI agents.

02

Security as product

At Brelo in Brazil, security was central to the device-locking technology we built and patented. Repeated jailbreak attempts made hardening and operational controls core product work.

03

Disciplines converge

Oktsec brings together that security foundation with two decades of building products, fintech and regulated systems. The current focus is agent identity, execution and software supply chains.

Security, product and regulated systems.

EARLY CAREER

Cybersecurity & software engineering

Cybersecurity was one of my first technical disciplines. I later expanded into software architecture, product leadership and regulated technology while keeping security embedded in how I built.

How I decide what to build.

01

Security from day one

Built in from the first commit, not bolted on after the incident.

02

Product over process

The goal is something people can use safely, not a checklist.

03

Open by default

Tools the ecosystem can inspect, trust and improve.
