Blumira sensors require outbound traffic to a specific subset of Google assets on the internet. We strongly recommend using URL/FQDN filtering where possible to allow traffic in locked down situations. However, in situations where this is not possible, we have attached a file of all Google Cloud IPs and Google IPs that must be whitelisted if performing IP-only whitelisting – last updated 2020-03-25.
Google Cloud IPs and Google IPs must be whitelisted if performing IP-only whitelisting – last updated 2020-03-25.
Blumira leverages a number of Google Cloud Platform services to provide you with a scalable and efficient experience. Part of that is the utilization of broad domains that leverage private key authentication within the Google Cloud Platform. This means that if there’s an issue in one region, DNS can round robin to other available and routed IPs.
If you were able to whitelist the above URLs/FQDNs you’re all set! If you require IP-based whitelisting, please refer to the attachment which contains line-separated CIDRs that must be whitelisted. An IPv6 list is also provided for any IPv6 needs.
