The Cisco Identity Services Engine (ISE) is a comprehensive network security solution designed to provide trusted access and enforce policies across your network. It plays a pivotal role in zero-trust architecture by acting as the policy decision point, gathering intelligence from various network components to authenticate users and endpoints while automatically containing threats. The latest version, Cisco ISE 3.4, enhances network security with operational flexibility and intelligent insights, ensuring that only trusted users and devices gain access to network resources.

Key Features of Cisco ISE

• Zero-Trust Network Access: Cisco ISE supports a zero-trust approach, ensuring that only verified users and devices can access network resources. It uses gathered intelligence to automatically identify, classify, and profile devices, enhancing security by containing potential threats swiftly.
• Operational Flexibility: The platform allows seamless integration with multicloud environments, enabling network access control (NAC) workloads to be managed across different cloud services. This flexibility is crucial for businesses operating in diverse IT environments.
• Comprehensive Policy Enforcement: With its Common Policy feature, Cisco ISE enables consistent policy enforcement across different domains. Users can leverage the same user, endpoint, and application context across multiple domains, providing flexibility in managing and enforcing security policies.
• Advanced Threat Detection: Cisco ISE provides advanced capabilities to detect and neutralize threats through live environment testing. This proactive threat management helps protect networks from hostile attacks.
• Device Posture Verification: The platform verifies device compliance with security policies, ensuring that all connected devices meet organizational security standards. This verification is crucial for maintaining a secure network environment.
• User and Device Management: Cisco ISE offers self-service portals for users to add and manage their own devices, reducing help desk tickets and improving user experience. Support for SAML 2.0 enhances this capability by providing secure authentication.
• Network Segmentation and Access Control: The solution supports virtual LAN (VLAN) assignments, dynamic Access Control Lists (dACLs), URL redirects, and named ACLs to quickly undermine unwanted connections and enhance network security.
• Cloud Integration: Cisco ISE optimizes applications and workloads running on AWS and integrates with Microsoft Azure to enhance application resources. These integrations provide additional options for deploying secure network solutions in cloud environments.
• Enterprise Agreement Flexibility: The Cisco Security Enterprise Agreement offers flexible buying options for security software, simplifying management with a single agreement.

Cisco ISE is designed to preserve business continuity by maintaining a resilient security posture that extends beyond initial authentication to provide session-long protection. This ensures that organizations can operate securely without disruptions while safeguarding their data and resources from potential threats
