Azure Security Center is a unified infrastructure security management system that strengthens the security posture of your data centers, and provides advanced threat protection across your hybrid workloads in the cloud - whether they're in Azure or not - as well as on premises. Azure Firewall Manager is a security management service that provides central security policy and route management for cloud-based security perimeters. To provide unified infrastructure and network security management to you, we have now integrated Azure Firewall Manager with the Azure Security Center.
With the integration of Azure Firewall Manager with Azure Security Center, customers will now have a single pane of glass view of their infrastructure and network security. Customers will be able to see the status of Network Security from the Azure Security Center directly. Customers will no longer have to go into 2 different blades: in ASC for infrastructure security and in Firewall Manager for Network Security.
