Brazil
Summary
🤩
Rockstar🎓
Top SchoolTiago Assumpcao is a cybersecurity leader with 25+ years of hands-on experience who currently scales threat intelligence and collaborative defense for the digital asset ecosystem as Technical Director at Crypto ISAC. He blends deep vulnerability research and secure engineering—having helped design early memory safety mechanisms like ASLR and XN—with practical program-building at scale, from embedded security at BlackBerry to leading SDLC reinforcement for Rootstock Labs protecting over $250M in TVL. Tiago has run long-term, embedded consulting engagements, managing large technical teams and multimillion-dollar portfolios while converting security findings into measurable business risk metrics. His research background spans advanced binary analysis (author of The Automated Cesar) and automated vulnerability discovery, complemented by operational threat investigations into state actor tradecraft targeting crypto. Equally comfortable in low-level exploit development and executive communication, he focuses on embedding security into engineering workflows to prevent systemic failures rather than merely fixing bugs. Based in Brazil, he also brings a unique perspective shaped by technical advising for national security initiatives and open-source tooling for binary analysis.
