VPC Service Controls helps protect against accidental or targeted action by external or insider entities, to minimize data exfiltration risks from Google Cloud services such as Cloud Storage and BigQuery. VPC Service Controls is used to create perimeters that protect the resources and data of services that are explicitly specified. By allowing private access only from authorized VPC networks, VPC Service Controls helps protect against data exfiltration by clients using stolen OAuth or service account credentials. VPC Service Controls adds a layer of security defense for Google Cloud services that is independent of Identity and Access Management (IAM). Google Cloud provides a restricted virtual IP that is integrated with VPC Service Controls. VPC Service Controls lets administrators monitor resource access patterns across service perimeters using Cloud Audit Logs. VPC Service Controls can run in dry run mode to monitor requests to protected services without preventing access.
