If you make the abilty, "immune to treason, and resists espionage" with an effect like No crew insurrection and no PPPs, with 20% of all enemy intel projects fail, I'd rate it as less likely to win you a game than a custom tech area. Shouldn't be more than 2000 in my mind. It is powerful, but it's not enough to get me to pick it up instead of psychic, organic, or crystal tech if I can only afford one or the other. I'd probably pick advanced storage over it if they both cost the same.
