What information do forensic reports offer?

Forensic reports provide historical sandbox data regarding potential infections, making this choice the most appropriate. These reports are crucial in the cybersecurity landscape as they analyze past incidents of malware or virus infections, examining how such threats were identified and contained. The focus on historical data allows organizations to understand the nature of the threats they face, including patterns of attacks, types of malware involved, and the effectiveness of response measures taken during those incidents.

In contrast, real-time data on internet usage is more commonly associated with monitoring tools that provide live insights into current internet activities, rather than past infection details. Insights on user engagement metrics typically pertain to tracking how users interact with applications or services but do not focus on the technical security aspects of infections. Finally, comparative analysis with competitors is related to market research and strategic positioning, which is outside the scope of what forensic reports provide. Overall, the correct answer emphasizes the report's role in offering a retrospective view on security incidents, aiding in improving future defense strategies.
