By "closed source," you mean government clandestine intelligence services? I used to work on ground processing software for the NRO and NSA, and yes, they know a lot more than the Internet, a lot more than law enforcement, and a lot more than they ever admit to knowing. Not revealing what you know is an intrinsic part of the spy game to prevent opponents from inferring your collection capabilities and current scope of assets. If your opponent knows what you can surveil, they just won't do that.

Yes I was looking for a better term but thought "closed source" fit in the context.

Thanks for the insight, I thought this would probably be the case.

Do you think traditional intelligence services have any blindspots that OSINT are managing to make headway? Even if overall the balance is far more in favour of traditional players?
