Open Source Intelligence (OSINT) is a different type of intelligence discipline. The difficulty is in identifying relevant, reliable sources from the vast amount of publicly available information. However, this is not as great a challenge for those who know how to access local knowledge and how to leverage human experts who can create new tailored knowledge on the fly. In this blog, we are going to provide you with a list of basic sources of OSINT or better yet the source of information that is widely used to gather intelligence on the web.
