Human context. Better intelligence.
OSINT investigator. Privacy manager. Cybersecurity speaker.
I investigate digital exposure, manage privacy work, and teach people to connect public information with human context. Book me to speak at your event or teach 3D OSINT to your team.
I’m Lindsey Yagi-Hatake, the OSINT Gremlin, also known in the cybersecurity community as ShieldNSlay. I work as an OSINT investigator and privacy manager at Decisive Resources. My work brings together public-source research, digital exposure assessment, and privacy management.
My path into OSINT began with learning how to protect myself from digital stalking and abuse. Those skills became the foundation of my professional investigative career. Today, I use those skills professionally and bring that practical perspective to conference audiences and company teams.
I offer conference talks and hands-on workshops on OSINT, verification, privacy, and human security. Six years of teaching experience and a master’s degree in education administration support how I deliver training: clear explanations, purposeful practice, and skills participants can apply.
“Stop separating human security from technical security.”
“You can map every device, account, domain, username and IP address perfectly and still misunderstand the incident because you never mapped the human environment.”
That is the gap my talks and training address. Trust by Proxy helps audiences recognize how credibility and belonging can be exploited. In 3D OSINT, participants practice combining purposeful questions, investigative principles, and digital research to build a fuller understanding of the people behind the information. From Exposure to Empowerment connects individuals’ digital exposure with company risk and teaches steps people can take to protect themselves and their workplace.
Bring this perspective to your next event, or give your team the opportunity to practice it through hands-on training.

We teach people how to identify phishing emails, but not how to identify predatory behavior wearing conference badges. Trust by Proxy explores trust as an attack surface and introduces 3D OSINT for verification.
A hands-on workshop combining conversation, investigative principles, and digital OSINT skills. Participants practice asking purposeful questions, separating observations from assumptions, and using public information to verify findings. Available for conference workshops and paid team training. Contact me to discuss your audience, goals, and format.
Using OSINT to Reclaim Power in a Digital World. Available as a talk or an employee workshop, this session connects personal digital exposure with organizational risk. Participants learn how publicly available information can be used to target people and their employers, and explore steps to protect accounts, reduce exposure, and make informed privacy decisions.
Conference talks, community conversations, and moments with the people who make this work matter.
