How does Zscaler ensure that its users have updated information about file threats?

Zscaler provides its users access to updated information about file threats primarily by uploading threat data to the cloud for all customers. This cloud-based approach allows Zscaler to aggregate and analyze threat intelligence from a wide array of sources, ensuring that all users benefit from the latest insights into emerging threats. By utilizing the cloud infrastructure, Zscaler can quickly distribute updated threat information across its global network, enabling instant protection for users as new threats are identified.

This system ensures that users are not just relying on local, outdated threat intelligence but are leveraging a continually refreshed database of potential threats that is accessible in real-time. The efficiency and speed of cloud computing facilitate rapid updates, which is crucial in the fast-paced world of cybersecurity where new vulnerabilities and attack methods can emerge daily.

The other options do not align with Zscaler's model for updating threat intelligence. For instance, not storing past threat data could hinder the understanding of ongoing patterns or previously encountered threats. Dynamically removing old threat feeds does not guarantee that users have the latest information; it might lead to situations where relevant threats are unintentionally lost. Peer-to-peer sharing, while potentially useful for certain types of data, lacks the centralized, comprehensive, and secure nature of the cloud model that Zscaler
