DNS Security is an on-demand cloud subscription
service designed to protect your organization from advanced threats
using DNS. By applying advanced machine learning and predictive
analytics to a diverse range of threat intelligence sources, DNS
Security generates an enhanced DNS signature set and provides real-time
analysis of DNS requests to effectively defend your network against
newly generated malicious domains. Because the DNS signatures and
protections generated through this service are distributed by the
cloud without the hardcoded limitations of the downloadable DNS
signature sets, you can access newly added content without downloading
and installing updates. To access the DNS Security service, you
must have a valid Threat Prevention and DNS Security license.
