ABOUT JACOB GAJEK
I bridge the gap between 15 years of adversarial \'ground truth\' and the next generation of Agentic AI security. I don\'t just research threats; I build the automated systems that hunt them.My career has been spent in the trenches, from developing kernel-level security software in C++ to leading threat-hunting engagements using EDR telemetry. Today, I am an Individual Contributor focused on the Adversarial Integrity of AI. I specialize in building and red-teaming AI Investigation Pipelines, ensuring that as we move toward an autonomous SOC, our models are hardened against prompt injection, evasion, and agentic misalignment.Core Technical Impact:Innovation Prototyping: I bridge the gap between research and production, developing new capabilities for AI pipelines that handle high-fidelity telemetry at scale.Adversarial Resilience: Lead Red Teaming initiatives for agentic security workflows, identifying and mitigating critical prompt injection vectors.Data-Driven Hunting: 5+ years of EDR-native threat hunting (CrowdStrike, SentinelOne, MDATP, Carbon Black) paired with ML-based telemetry analytics in Python, Java and C#.
