Huntress now supports an IP address allow list for isolated hosts, but this doesn't work with Cloud RMM, AV, or other tooling which typically uses dynamic IP addresses for agent connectivity. Vote here if you'd like to see this capability added.
Even better, it would be great to hear what specific tools you'd want to use it with; the list of DNS names that need allowing for typical cloud tooling is long, and we could potentially preconfigure them (just check a box) for common-needed tools.
