Cloud Firewall provided by Alibaba Cloud is the first Firewall as a Service (FWaaS) solution for public clouds. Cloud Firewall allows you to manage the following types of policies in a centralized manner: access control policies that are used to control north-south traffic and microsegmentation policies that are used to control east-west traffic. Cloud Firewall provides a built-in intrusion prevention system (IPS), which allows you to view network-wide traffic and access relationships among your services. Cloud Firewall is the primary infrastructure that you can use to protect your services in Alibaba Cloud.
