On April 25, 1947, America’s first Civil Center Intelligence Director, Allen Dulles, presented a nine-page article to the senate, the so-called “the art of intelligence.”. He has made striking claims and determinations about the OSINT (Open Source Intelligence) model, which has received much attention from the security ecosystem in recent years. At the end of the day, Dulles stressed that 80% of the information they call “intelligence” is obtained from open sources.
After a while, Arthur S. Hulnick, a centuries-old veteran of the CIA, who taught at the University of Boston, said that up to 80% of America’s intelligence during the entire cold war was obtained as open source intelligence. Finally, in 2005, former Central Intelligence manager W.M. Nolte said that 95% to 98% of the entire US intelligence ecosystem is open source intelligence.
