About Me

About Me

I’m Stefan Cooke, an IT Systems Engineer specializing in secure systems deployment, asset protection, and multi-tenant operations.

Who Am I?

Nice to meet you! I’m Stefan, an engineer focused on bridging the gap between high-availability infrastructure and rigid security frameworks. With an NCSC-certified background in Cyber Security for Computer Science and hands-on operational experience at companies like Google and Hexarad, I specialize in keeping critical digital assets secure, resilient, and compliant.

My day-to-day work involves navigating complex network perimeters, automating deployment pipelines, and managing identity and access management (IAM) strategies across highly distributed, enterprise-scale environments. Whether deploying hardware on physical sites or securing logical remote infrastructure, I approach every challenge with a security-first, zero-trust mentality.

How I deliver?

Security-First Automation & Architecture

I believe that robust security should integrate seamlessly with operations rather than slow it down. I enjoy writing automated routines to eliminate human intervention risks, creating secure deployment baselines with PowerShell, and leveraging automation tools like Ansible to reduce vulnerabilities.

Identity & Perimeter Defense
Managing infrastructure across 20+ distinct NHS trusts and enterprise networks has given me a deep appreciation for complex network boundaries, isolated perimeters, and bulletproof credential segregation. I excel at building and managing secure access pipelines—utilizing tools like Authelia for MFA/SSO and Bitwarden for zero-trust vault management—to guarantee that data and systems remain strictly protected.

Operational Leadership & Compliance
I thrive in high-stakes environments where reliability is non-negotiable. From conducting over 200 physical asset security audits to leading engineering teams to scale compliance protocols from 15% to 70% in a single month, I focus on delivering metric-driven results that protect both the physical and digital integrity of an organization.

My Mission

To build, optimize, and defend the physical and digital infrastructure that powers modern enterprise systems. I strive to combine deep technical execution with clear cross-functional communication to help organizations scale safely against an evolving threat landscape.

Let’s Chat!

I am always looking to connect with fellow engineers, security practitioners, and tech enthusiasts. Whether you want to talk about network architecture, zero-trust infrastructure, automation workflows, or even judo—let’s connect!
