The people building tools to protect America's networks often trained in the same Israeli military spy unit.
Who they are

Yossi Appleboum is a graduate of Israel's military signals-intelligence unit (Unit 8200) and founder of a cybersecurity company called Sepio.

What they do

Sepio makes technology for spotting rogue or malicious hardware plugged into a network, and its tech was highlighted by the US government's cybersecurity agency, CISA.

How it works

He came out of Israel's Unit 8200, then built a company whose product got recognition from CISA, the American agency that guards critical computer systems.

Why it matters

It's one concrete example of a bigger pattern the engine tracks: veterans of an Israeli military intelligence unit ending up wired into the infrastructure that protects US networks.
