About

I’m Dan Cohen Vaxman, a Senior Security Engineer with 6 years of experience spanning incident response, cloud security, offensive security, and security automation. I work across the full lifecycle — proactively hardening systems and hunting for weaknesses, then responding fast when something slips through.

Core Expertise

• Incident Response – triage, containment, and post-incident hardening
• Cloud Security – securing cloud-native infrastructure and IaC at scale
• Offensive Security – web and infrastructure penetration testing
• Vulnerability Management – discovery, prioritization, and remediation
• Security Automation & DevSecOps – CI/CD hardening, drift detection, automated audits
• AI Security – hardening AI/ML pipelines and agentic systems

Languages & Tooling

Python · Terraform · Bash · SQL · jq · TypeScript

I write about all of this on the SentinelByte blog, sharing the research and hands-on techniques behind the work.
