Yes spying will be present, however there will be counterintelligence also so Empire being spied on could actually use it to it's own advantage, it's all the part of a game. Example: Highest ranking officers from couple of stronger TR outfits could set up a secret operation using only their elite and most loyal/battle proven members.Meanwhile other lower ranking soldiers from genpop will get completely other set of objectives in order to deceive both the enemy and possible spies within your empire. If someone actually goes to such a length to rise up that high in your Empire simply to spy then I would have to say nicely played and bow to them.
