About
Sassafras is where we write about defending agentic systems.
Collaborators
Zachary Hunsaker, Philip Taggart, and Spencer Cutrell.
Zachary Hunsaker
Zac works in cybersecurity and intelligence, focused on AI and agentic security. He is a Principal Engineer at AbbVie, where he builds agentic systems for the threat intelligence team, and he holds a Master's in Applied Intelligence from Georgetown University.
Before AbbVie he was an incident responder and security architect at the National Center for Atmospheric Research, supporting COSMIC II, a mission that launched six satellites for atmospheric research. He received awards for that work. At AWS he contributed to threat modeling for the CloudFormation team and to the security of infrastructure as code.
The work runs through open-source intelligence, threat modeling, security architecture, digital forensics, threat intelligence, privacy, and operational security. He builds much of the tooling in Elixir.
Philip Taggart
Philip is a retired Navy Commander who flew the F/A-18F Super Hornet before transitioning to the reserves and working with the Intelligence Community in Cyber Threat Intelligence. He has a Master's Degree in Computer Science and has worked in the public and private sectors including both MITRE, where he built tools to combat cybercrime, and AbbVie, where he built an AI powered threat intelligence platform. He has extensive experience leveraging AI and traditional machine learning across multiple domains. He now leads the cyber engineering efforts at a small defense contractor, also while managing projects across integrated air and missile defense.
His background spans defensive cyber operations at the JFHQ-DODIN Intelligence Directorate, integrating across 40+ federal agencies, and over a decade of operational leadership as an F/A-18 mission commander with 40+ combat missions. He brings that same operational rigor to engineering: systems that work under pressure, at scale, when it matters.
Spencer Cutrell
Spencer has formal experience and training in logic, low level computer systems, philosophy among other things. He is fantastic at finding solutions to complex problems. Those skills have been utilized in critical industries like transportation and financial services to protect both life and property. Spencer is particularly situated in the development of ethical AI programs or fine tuning agentic workflows to optimize for logical reasoning.
He holds a philosopher's instinct for first principles and an engineer's instinct for shipping, and he writes from both.
Open source
Elixir libraries for the security and intelligence community — OSINT collection, threat intel APIs, domain analysis, and more.
