Chen Shiri: Cybersecurity Researcher • Speaker • Engineer

I research, break, and explain modern systems – from cloud infrastructure to AI and share the thinking behind real-world security research.

My work has uncovered vulnerabilities in services used by millions, been cited by major news outlets, and presented at security conferences across the US and Europe.

I also built ByteBuzz- where engineers and hackers learn by doing.

01 // CORE_MISSION

What I Do

Cybersecurity Research

Finding complex vulnerabilities in cloud infrastructure, Kubernetes, containers, and AI systems – documenting the methodology and publishing the findings.

VULN_DISCOVERYCLOUD_SEC

Understanding Systems

Before you can break something, you have to understand how it works. Deconstructing modern systems and services- asking why, not just what.

INFRASTRUCTURELogic

Speaking & Education

Translating complex technical findings into actionable insights for global conferences and workshops. Mentoring engineers entering cybersecurity without a conventional path.

KEYNOTESMentorship

Building ByteBuzz

Built a hands-on learning platform where engineers and hackers master security by breaking real systems – labs, courses, and challenges derived directly from real research.

PROJECT // BYTEBUZZ

Stop Watching. Start Building.

I built ByteBuzz – a platform where you don’t just learn, you build and break real systems. Master the terminal, cloud, and code in a high-stakes environment.
