A mission-driven unit.
Task Force Investigation & Security (TFIS) is a veteran-founded, veteran/first responder operated investigative and security agency that upholds the uncompromising standards of America’s finest military units.
Who we are
Battlefield precision. Civilian operations.
We are not just a civilian company with a military aesthetic — we are a disciplined, mission-driven unit providing business solutions and consulting services that execute civilian operations with battlefield precision, professionalism and integrity.
TFIS delivers elite-level process service, private investigation, bail enforcement and executive protection to individuals, businesses and institutions across Oklahoma and beyond. Our Operators adhere to strict standards of conduct, appearance, FBI fitness standards and operational readiness. Every Operator is trained to the full scope of the unit’s capabilities — to perform under pressure, maintain client confidentiality and execute their duties with professionalism and respect.
Whether serving critical legal documents, conducting high-stakes investigations, locating missing persons, or protecting people and assets, TFIS operates with the discipline of a military unit and the precision of a specialized task force.
Our goal is simple: to provide elite-level task unit resources of the military to the citizens of this great nation.
