Cables Under Pressure: Securing Europe’s Subsea Cables

In this episode of Cache Me if You Can, we dive beneath the surface to explore the fragile networks that keep the world connected. Our guest, Dr. Anna-Maria Osula, Cyber and Economic Counselor at the Estonian Embassy in Washington D.C., unpacks the geopolitical and technical stakes of securing subsea cables. We discuss Europe’s emerging Cable Security Action Plan, NATO’s new Baltic Sentry surveillance mission, and how hybrid threats, from anchor drags to covert sabotage, are reshaping the way allies think about resilience. Together, we examine what happens when the world’s data highways become battlefields, and what Europe’s experience can teach the rest of the world about protecting the foundations of the digital age.
