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.
