Alex Bourla

Hands-on Cybersecurity Expert

Helping teams defend and design secure, modern systems

About

I help ambitious teams turn security into a strength, not a bottleneck. Whether you need strategic guidance or hands-on execution, I bring the experience to harden systems, reduce risk, and move fast without breaking things.

My background spans cloud-native security, secure design, and offensive security, from threat modelling and modern control implementation to red teaming and secure build pipelines.

Working with organisations of all sizes, from fintechs to critical infrastructure providers, I bring a builder’s mindset to security, with a focus on real-world impact, risk-based thinking, and cost-effective solutions that actually make a difference.
