Egress filtering is a popular network management technique. It scans all egress traffic for any sign of abnormality or malicious activity and then discards any infected data packets.

Techopedia Explains Egress Traffic

Egress traffic is a term used to define the volume and substance of traffic transmitted from the host network to an external network destination.

Egress traffic also contains request packets. These are destined for an application hosted on a remote server, jeopardizing the integrity and availability of the network. To counteract this problem, all egress traffic is filtered. In the case of a security or throughput breach, the traffic is capped. Egress traffic filtering not only ensures that malicious packets do not leave the network, but also manages the flow of information by restricting useless traffic.
