1. Data Collection: Azure Security Center primarily focuses on monitoring and protecting Azure resources and workloads, while Cisco Identity Services Engine is more focused on securing network access by enforcing policies based on user and device identity. Azure Security Center collects data from Azure resources and analyzes it to provide security recommendations, whereas Cisco Identity Services Engine collects data from network traffic and endpoint devices to enforce access control policies.
2. Integration: Azure Security Center integrates with various Microsoft Azure services and third-party security solutions to provide a comprehensive security ecosystem within the Azure environment. In contrast, Cisco Identity Services Engine integrates with Cisco network infrastructure and other network security solutions to enforce access policies across the network.
3. Deployment: Azure Security Center is a cloud-native security solution that is deployed within the Azure platform, offering centralized security management and monitoring for Azure resources. On the other hand, Cisco Identity Services Engine is typically deployed on-premises, serving as a network access control solution that enforces policies at the network level.
4. Focus: Azure Security Center focuses on securing cloud resources and workloads by providing threat protection, vulnerability management, and security posture management for Azure environments. In contrast, Cisco Identity Services Engine is focused on securing network access and ensuring compliance by authenticating and authorizing users and devices before granting access to the network.
5. Scalability: Azure Security Center is designed to scale with the growth of Azure resources and workloads, providing security insights and recommendations across large-scale Azure environments. Cisco Identity Services Engine is also scalable to accommodate network growth and changes, ensuring consistent access control and policy enforcement across an expanding network infrastructure.

In Summary, the key differences between Azure Security Center and Cisco Identity Services Engine lie in their focus on data collection, integration, deployment, primary focus, and scalability within their respective security domains.
