Rockstar🎓
Top SchoolOmer Yampel is a detection engineering leader with 11 years of hands-on DFIR, incident response, and security automation experience, currently leading Detection Engineering at Citadel in New York. He blends deep technical expertise—malware analysis, digital forensics, reverse engineering and security tooling—with a strong software background (BSc and MSc in Computer Science, near-perfect GPAs). Previously he led incident response teams at Cybereason and built security automation and Splunk apps at Sony, and as a sergeant in the Israeli Air Force’s CERT he developed DFIR tools used in operational investigations. An active open-source contributor, Omer has improved backend tooling for projects like Beagle (graph-based forensics) and Velociraptor (VQL plugins, cloud pub/sub, and TLS automation), showing an ability to bridge research, engineering and production ops. Colleagues rely on him to turn complex forensic data into scalable detection logic and reproducible incident workflows.
