CI Press, Episode 73: Counterintelligence Through the Ages: From Pyramids to the Cold War

Replay:  On Part 4 of CI Press Demystifying CI Series, co‑hosts Jeremy Clark and Ryan Rambo explain the key difference between counterintelligence and HUMINT, then take listeners on a brisk historical tour of CI from ancient Egypt and Babylon through Troy, Greece, Rome, the Renaissance, and the Revolutionary and World Wars up to the start of the Cold War. The episode highlights recurring CI themes - deception, double agents, surveillance, sabotage prevention - and covers the rise of formal services (MI5/MI6, Pinkertons, OSS/CIA, FBI), practical tradecraft, and why protecting information remains vital today.
