What technique is used to prevent phishing attacks in Palo Alto Networks?

The correct choice effectively addresses the methods employed by Palo Alto Networks to combat phishing attacks. URL filtering is a critical component, as it allows organizations to block access to malicious websites known for phishing scams. This feature works by maintaining a database of URLs that are categorized based on their reputation and risk level, enabling the firewall to prevent users from visiting potentially harmful sites.

In addition to URL filtering, anti-phishing services provided by Palo Alto Networks actively detect and block phishing attempts through sophisticated algorithms and machine learning techniques. These services monitor various signals and indicators of phishing attacks, such as unusual email patterns, suspicious links, and domain impersonation tactics, enhancing the organization's overall security posture.

Together, URL filtering and anti-phishing services create a robust defense mechanism against phishing threats, as they not only restrict access to harmful sites but also proactively identify and combat phishing schemes before they can harm users or the network. This combined approach ensures that users are protected while browsing and interacting with online content, significantly reducing the risk of falling victim to phishing attacks.
