What tool helps an incident responder in detecting phishing attempts against an organization?

The most appropriate tool for detecting phishing attempts against an organization is PhishAlert. This tool is designed specifically to help organizations identify and respond to phishing attempts. PhishAlert enables users to report suspicious emails directly to their security teams with a simple click, which facilitates quicker investigation and response to potential threats.

While Scany, MailChimp, and SpamHero may have features that could indirectly contribute to phishing detection or email management, they do not provide the focused functionality that PhishAlert does. Scany is more oriented towards vulnerability scanning, MailChimp is primarily an email marketing platform that lacks security features targeting phishing specifically, and SpamHero is concerned with spam filtering but does not offer the incident response capabilities that a tool like PhishAlert provides.

Thus, PhishAlert stands out as the dedicated solution for responding to and managing phishing threats effectively within an organization.
