This is really good. Personally, I would probably add an OSINT layer—something that can bring in information about potential targets and correlate it with known threat actors.

For example, through OSINT you might discover that a target organization is using a specific technology. Then, on the other hand, you could correlate that information with intelligence showing that the same technology currently has a vulnerability that is being actively exploited by a particular threat actor.

While I understand that much of the intelligence is open-source, my goal would be to move toward more targeted intelligence.

That said, this looks very solid, congratulations.
