To help determine which computer forensics tool to purchase, a comparison table of functions, subfunctions, and vendor products is useful.

• A. Sometimes
• B. False
• C. True
• D. Not applicable

Answer: (C)

Using a comparison table that lists functions, subfunctions, and vendor products helps you translate your investigation needs into concrete, checkable criteria and see which tools actually cover them. It provides an objective, side-by-side view of capabilities such as data acquisition, processing and filtering, artifact support (emails, web history, cloud data), timeline analysis, reporting, automation, platform compatibility, licensing, and vendor support. By detailing how each tool handles each function, you can identify gaps, prioritize requirements, and justify the purchase with concrete evidence instead of marketing impressions. Build the table by listing the essential functions you need, break them into subfunctions, fill in each product’s documented support, and note any limitations or test results. This approach is most effective when paired with hands-on trials and real workflow considerations to ensure the selected tool fits your own case types and governance needs.
