Build a Firewall and an Email Server

You can use the Entity Find block to monitor multiple blocks in a model, to examine, and to extract entities.

This example represents an email server with a firewall to track, monitor, and discard harmful emails before they reach the user. In the model, emails are generated using an Entity Generator block. In the Firewall component, all emails are classified as harmful for instant discarding, suspicious for monitoring, or safe based on their source. Harmful emails are tagged with a DiscardTag resource from the Resource Pool block and instantly discarded from the system. Suspicious emails are tagged with MonitorTag and tracked throughout the system for suspicious activity. If a suspicious activity is detected, the email is discarded before it reaches the user. Safe emails are not monitored or discarded.
