Can you provide the IP addresses/ranges that should be whitelisted to allow hosts to communicate with huntress.io?
We do not have dedicated IP addresses or an FQDN to be used with inbound filtering rules (This typically would be used to filter incoming traffic from Huntress to your PSA).
We utilize a fully scalable infrastructure within the Amazon Web Services (AWS) platform. In order to maintain redundant connectivity and allow for failover there are no static IP addresses/FQDNs.
If you restrict outbound traffic, you will need to allow outbound communication to huntress.io and huntress-installers.s3.amazonaws.com over port 443.
