In general the NSA functions more like 2 agencies, one focused on the "red" side (hacking, breaking crypto, sigint stuff) and one focused on the "blue" side (protecting US assets from being hacked, developing better/new crypto, providing guidance on security).

Both sides are good at their jobs and for what it's worth, my understanding is that the blue side really does want to keep your shit from being hacked.
