Correct me if I'm wrong, but the NSA leaks have all been the result of internal employees leaking outward, rather than outside people reaching inward where they shouldn't. That's a meaningful distinction, IMO. They call for two completely different types of defense.
This is inexcusable in 2017. Hacking humans may be easier but it's up to Equifax to figure out how to mitigate that risk. "It's hard" doesn't excuse their behavior.
