Because the standard tools are commoditized. If every foundry in your region uses the same open-source solver (like OpenFOAM-based casting modules), nobody has a competitive advantage. You are all making the same mistakes.
While the public release notes will mention "performance improvements," here is the real story.
Its foundational purpose is to process Call Detail Records (CDRs) and tower dump data, which are traditionally provided by telecom giants like AT&T, T-Mobile, and Verizon as dense Excel worksheets or CSV files. Instead of forcing analysts to manually cross-reference hundreds of rows of geographic coordinates and timestamps, CASTViz automates the plotting of these connection events onto interactive visuals.

Perhaps the most distinctive characteristic of CASTViz is its . The software is not sold to the public, private companies, or foreign governments. Instead, CASTViz is provided free of charge exclusively to sworn law enforcement officers and accredited criminal justice agencies within the United States. Access is typically granted through participation in FBI‑CAST training courses. For example, the “CAST Basic Historical Cell Site Analysis” course—a two‑day, no‑cost training program—requires attendees to bring a department‑issued laptop and provides them with a copy of CASTViz to take back to their agency. This controlled distribution ensures that the software remains in the hands of trained professionals who understand its capabilities and legal limitations.
Access to CASTViz is strictly controlled. Law enforcement personnel cannot simply download it from a public website. Instead, agencies send officers to attend FBI CAST Basic training courses. These are often 2-day sessions offered through regional training centers or technical colleges in partnership with the FBI. Because the standard tools are commoditized
It processes massive CSV or Excel files detailing cell-site and call data records.
But this is not just another software review. This is an exploration of the —the specific features, partnerships, and proprietary algorithms that set this platform apart from competitors like MAGMASOFT, AnyCasting, or ProCAST. While the public release notes will mention "performance
While sometimes categorized as "freeware" within government circles, it has no associated licensing fee for authorized agencies. ⚠️ Known Risks & Limitations
Legal admissibility is critical in any investigation. CASTViz includes functionality to generate professional, court-ready charts and exhibits. These visualizations help attorneys, judges, and juries understand complex technical data without needing a degree in telecommunications engineering. The ability to present a clear map showing a suspect’s phone traveling to a crime scene is a powerful tool in the courtroom.
While the frontend user interface provides clean maps and charts, the backend architecture relies on a highly secure, offline-capable tech stack:
