What specific threats does Advanced Threat Protection in Zscaler target?

Advanced Threat Protection in Zscaler specifically targets common attacks like phishing, as well as other sophisticated threats that can compromise security in an organization's network. Phishing attacks are a prevalent and critical threat in the digital landscape, often attempting to manipulate users into divulging sensitive information or downloading malware.

The functionality of Advanced Threat Protection includes analyzing incoming data traffic, identifying and blocking suspicious behavior, and providing real-time protection against these types of attacks, thereby ensuring that users are safeguarded from fraudulent attempts that can lead to data breaches or other security incidents.

While the other options mention valid security threats and concerns—such as known viruses, unidentified internal threats, and physical security risks—they do not encapsulate the comprehensive approach that Advanced Threat Protection has in specifically combating the wide range of tactics utilized in phishing attacks and similar threats. This focus on common attack vectors makes option B the most relevant choice regarding the objectives of Zscaler's Advanced Threat Protection.
