Blumira leverages a number of Google Cloud Platform services to provide you with a scalable and efficient experience. If you require strict outbound traffic filtering (e.g., for PCI compliance), then you must allowlist traffic to a specific subset of Google assets on the internet. We strongly recommend using URL/FQDN filtering where possible. However, if you cannot allow this for your organization, then you must add all Google Cloud IPs and Google IPs to an allowlist. This article explains how to do both.
