How does Sophos track user behavior on networks?

Sophos tracks user behavior on networks primarily through its User Activity and Web Filtering functionality. This method provides in-depth insights into how users interact with the network by recording their activities, monitoring web usage, and applying policies to control access to various web resources.

User Activity features allow organizations to see which applications and websites users are accessing, along with the duration and nature of those interactions. Additionally, Web Filtering enables administrators to implement rules that either permit or restrict access to specific websites or categories of content based on organizational policies. By combining these functionalities, Sophos not only helps in understanding user behavior but also enhances security by managing potential risks associated with inappropriate web usage or access to harmful sites.

The other options don't accurately represent how Sophos tracks behavior; physical surveillance is not a method used in network monitoring, cookies are specific to browsing behavior rather than overall network usage, and analyzing only user login times lacks the depth required for understanding comprehensive user activity.
