August 19, 2025—Email and Collaboration Security now offers a centralized location
for managing policy-related resources and performing email security operations across
supported solutions.
The first available feature is the approved and blocked lists, enabling administrators
to define trusted or suspicious senders and content once and apply them consistently
across supported solutions, including Cloud Email and Collaboration
Protection and Cloud Email Gateway
Protection. This reduces duplicated setup effort and ensures uniform enforcement. For solution-specific
control, configurations can still be made individually.
In this release, only sender addresses are supported for the approved list, with more
object types and common lists coming soon under Policy Resources.
