There's only one planet where hexenon is available, and generally there's only the one defense node per planet (there's about one of each mission type per planet).

Mystery solved.

Alternatively looking up 'Hexenon' or 'Defense' on this wiki would have told you exactly where it is.

Hearing and knowing about things to do in Warframe, and well... things to know is a bit like picking up side-quests in Mass Effect 3 - you overhear some people mention something interesting, then we just get to work taking our first clue from something they mentioned, and branching out from there.
