There have been a number of people who have reported to us about seeing "IP Reputation Attacks" from an app called Xfinity.
There are also a number of people who have reported a similar issue on the Xfinity forum - https://forums.xfinity.com/conversations/search?q=ip%20reputation
From what we can gather, Amber X does not seem to be a specific target as it appears it could be any device on your network. Users on the Xfinity forum have suggested turning off the advanced security feature in Xfinity or simply ignoring it.
In terms of Amber X's security, Amber X does not require port forwarding and is a highly secure product as suggested by its selection for the CES 2021 Innovation Awards Honoree for Cybersecurity and Personal Privacy.
