“Protective intelligence is the process of gathering and assessing information about persons who may have the interest, motive, intention, and capability of mounting attacks against public officials and figures.” – USSS Protective Intelligence & Threat Assessment Investigations: A Guide for State and Local Law Enforcement Officials

“Open-source intelligence (OSINT) is intelligence collected from publicly available sources. In the intelligence community (IC), the term “open” refers to overt, publicly available sources (as opposed to covert or clandestine sources); drawn from publicly available material, including: the Internet, the media, photos and geospatial information.” – CIA DNI Open Source Center

Below, we have put together a list of highly effective resources we use while conducting OSINT investigations for protective intelligence; and remember, information is the data obtained through research and the resultant actionable conclusions we formulate from that data is the intelligence.
