About
About Cleiver Souza — Security engineer, hacker, and cloud-native enthusiast.
Security engineer by day, hacker by curiosity.
With 17 years in IT, I’ve built a solid foundation in Cyber Security, working across Cloud Security, DevSecOps, and Blue Team operations. I help organizations strengthen their defenses in complex, high-scale environments — from threat detection and incident response to vulnerability management and secure-by-design architectures.
My focus is on cloud-native security strategy, with hands-on experience across the CNCF ecosystem. I write about offensive security, cloud-native defense, and the tools and techniques that actually matter in the field — because breaking things is how you learn to build them right.
- 🔍 Threat Detection & Incident Response
- ☁️ Cloud Security (AWS, GCP, Azure)
- 🔄 DevSecOps shifting security left
- 🐳 CNCF Ecosystem Kubernetes, Falco, OPA, and more
- 🏗️ Security by Design secure architectures from the ground up
- 🎯 Blue Team Operations defense at scale
- 🐞 Vulnerability Management
Because security knowledge should be shared, not hoarded. Here you’ll find writeups, deep dives, and hands-on content about offensive security, cloud-native defense, and the CNCF landscape — written by someone who spends their days (and nights) in the trenches.
No fluff. Just real-world stuff that actually matters.
