To improve response times to threats, which setting should be enabled under the Safe Links policy?

Enabling the setting that does not allow users to click through to the original URL is beneficial for improving response times to threats as it helps ensure that users are protected from potentially malicious content. When users are redirected through the Safe Links mechanism, this process checks the URL against a constantly updated list of threats before allowing access to the original link. By preventing users from bypassing this protection, organizations can reduce the risk of exposure to harmful elements in phishing attempts and other online threats.

This measure is crucial for enhancing the overall security posture and streamlining the response to potential threats. The policy ensures that all users remain within the controlled environment of the Safe Links service rather than navigating directly to potentially dangerous sites. This can significantly reduce the response time needed by security teams to identify and mitigate incoming threats, as users are safeguarded by the checks integrated into the Safe Links feature.

In contrast, other options either focus on different aspects of security or are less relevant to immediate threat response times. For example, applying Safe Links to messages internally enhances security but does not impact response time directly. Similarly, scanning downloadable content or not tracking user clicks may contribute to security but doesn't specifically streamline the immediate handling of threats in the same way that restricting users from clicking the original URLs does.
