Sector 7 a secret government agency, so secret that the rest of the government don't know who they are, tasked in dealing and reverse engineer NBE's. That's one face. But from Simmon's statement modern technology reversed engineered from Megatron suggests some private sector involvement. Meaning they don't necessarily get most of their checks from the government. What if Sector 7 still exist but now out of government control? Oh on Simmons , for being such a basket case, I'd think any descent clandestine group would cut him loose.
