Port 5228 shows hpvroom when it is chrome

edit

The answer was one simple search away: https://www.speedguide.net/port.php?port=5228, and here. It states:

Google Chrome user settings sync (facorites, history, passwords) uses port 5228

PS: If management is 'freaking out' over a port access it should educate itself on modern day networking, IMHO.

Chrome currently uses Firebase Cloud Messaging (FCM) as its push service. FCM recently adopted the Web Push protocol. FCM is the successor to Google Cloud Messaging (GCM) and supports the same functionality and more.

If your organization has a firewall to restrict traffic to or from the Internet, you need to configure it to allow mobile devices to connect with FCM in order for devices on your network to receive messages. FCM typically uses port 5228, but it sometimes uses 5229 and 5230.

The traffic is probably encrypted so not what you will get if setting decode to TLS for port 5228
You can map the port number to "google" by setting up a personal "services" files: https://www.wireshark.org/docs/man-pa...

Name Resolution (services)
The services file is used to translate port numbers into names. Both the global services file and personal services files are used if they exist.

The file has the standard services file syntax; each line contains one (service) name and one transport identifier separated by white space. The transport identifier includes one port number and one transport protocol name (typically tcp, udp, or sctp) separated by a /.

An example is:

mydns 5045/udp # My own Domain Name Server mydns 5045/tcp # My own Domain Name Server

Put your custom "services" file in the folder pointed to by Help->About->Folders: Personal Configuration My services file for testing:

google      5228/tcp    # Google Cloud/Firebase messaging
