When a site is Auto-Blocked by Default Threat Protection, what is true about the traffic to and from that site?

When a site is Auto-Blocked by Default Threat Protection, all traffic from that site is indeed blocked. This means that the firebox will prevent any inbound communications originating from the blocked site, effectively stopping any potentially harmful data from reaching your network.

This blocking serves to protect the network from possible threats that could arise from malicious activities associated with that specific site. It's important to note that while traffic from the site is blocked, it does not imply that all traffic to the site is entirely blocked or permanently blocked, nor does it address a temporary restriction. The key focus here is on securing the network by preventing incoming traffic that could pose a risk. Thus, understanding the mechanics behind what happens to the traffic originating from a site under threat protection is crucial for maintaining network security.
