1. Identity-based Access Control: Cisco ISE leverages identity attributes such as usernames, group memberships, and device characteristics to enforce granular access policies. It allows organizations to dynamically control network access based on user identities, ensuring only authorized individuals and devices gain entry.
2. Network Segmentation: With Cisco ISE, network administrators can implement secure network segmentation through virtual local area networks (VLANs), Security Group Tags (SGTs), and TrustSec technology. This enables the isolation of different user groups and devices, enhancing network security and reducing the attack surface.
3. Policy-Based Automation: Cisco ISE provides a policy-based framework that enables automated provisioning of network access and services. It allows organizations to define rules and policies that automatically assign appropriate access privileges based on user roles, device types, and contextual information, streamlining network operations.
4. Device Profiling: Cisco ISE has built-in device profiling capabilities that automatically identify and categorize devices based on their characteristics and behavior. It helps administrators understand the types of devices connecting to the network, ensuring better visibility and enabling the enforcement of device-specific policies.
5. Guest Access Management: Cisco ISE simplifies guest access management by providing a self-service portal for guest users. It enables organizations to create customized guest access workflows, allowing visitors to authenticate securely, receive limited network access, and adhere to predefined policies without IT intervention.
6. Posture Assessment: Cisco ISE includes posture assessment capabilities to evaluate the security posture of connecting devices. It verifies if devices comply with predefined security requirements, such as running updated antivirus software or having the latest operating system patches. Non-compliant devices can be placed in a restricted network segment or directed to remediation actions.
7. Threat-Centric NAC Integration: Cisco ISE integrates with threat detection systems, such as Cisco Stealthwatch and Cisco Advanced Malware Protection (AMP), allowing network access policies to dynamically respond to potential threats. This integration enhances threat detection and response capabilities by combining network visibility and security enforcement.
8. Profound Network Visibility: Cisco ISE provides detailed visibility into network access events, user activities, and device behaviors. It offers comprehensive reporting and analytics to identify anomalies, detect security incidents, and support compliance requirements. This visibility empowers administrators to make informed decisions and respond effectively to network events.
9. Integration and Ecosystem Support: Cisco ISE integrates seamlessly with other Cisco security products and a wide range of third-party solutions, creating an ecosystem for holistic security management. It enables organizations to leverage existing investments and extend their security posture with additional capabilities.

These technical features of Cisco ISE work together to establish a robust security infrastructure, streamline access control processes, and enhance network visibility, making it a formidable solution for organizations seeking to protect their networks and resources.
