OSINT and open-source data (OSD) may be used interchangeably, but they are distinct concepts. OSD refers to publicly available information sourced from the internet, including social media, online news, and sanctions lists. On the other hand, OSINT is the outcome of studying, analyzing, and using OSD to make informed decisions. While anyone can access and gather OSD, it takes trained investigators to turn that information into valuable OSINT insights.
