Kate's organization has been experiencing successful phishing assaults, and she spots a new email containing a link to a phishing site. Which option from the following is MOST likely to prevent the phishing attack from triumphing over her users?

The most effective solution for Kate would be to employ a URL filter, which would prohibit users from accessing the link in the phishing email. A web application firewall (WAF) is intended to thwart attacks on a web application. Patching can aid in preventing the exploitation of exposed systems or services, but since this is a phishing attack, it is not applicable. An allow list outlines permitted items, not blocked items, and in most cases, restricting which websites an entire organization can access is nearly impossible.
