Allowlisting domains for firewalls

I have a firewall in place. What domains must I allowlist to configure Density devices to work with my network?

To allow Sensors to communicate with all needed Density services, please allowlist the following domains:

• *.density.io (port 443)
• *.amazonaws.com
• *.gstatic.com

An Internal DNS server is strongly recommended. If using Public DNS, please ensure the following are allowlisted (optional):

• 8.8.8.8
• 8.8.4.4

An internal NTP server is strongly recommended. For NTP and time synchronization, please ensure the following are allowlisted:

• *connman.net
• *.ntp.org (port 123)

Note: A list of the specific subdomains Density sensors communicate to can be provided upon request.

See our Technical Specifications for more details.
