Investigators today operate in an environment defined by rapid technological change. The number of available OSINT platforms, analytical tools, and data sources continues to expand at an unprecedented rate.

Many investigators rely on a core set of tools that they have used for years, while others adopt new platforms based on peer recommendations, conference demonstrations, or vendor marketing. In both cases, organizations often lack a structured methodology for assessing tools, comparing capabilities, and determining how they fit within existing investigative processes.
