Cisco ISE integrates with more than 60 third-party solutions that span across security and network portfolios. These solutions include network access devices, firewalls, threat detection and prevention systems, vulnerability scanners, endpoint management platforms, cloud services, and more. By integrating with these solutions, Cisco ISE can leverage the information and capabilities of these solutions to enhance the identity and access management, network visibility and segmentation, threat detection and response, and policy enforcement of the network. Some of the examples of third-party solutions that integrate with Cisco ISE are:

Fortinet: Fortinet integrates with Cisco ISE through pxGrid to share user and device information, security group tags, and endpoint posture status. This enables Fortinet to apply granular and dynamic firewall policies based on the identity and context of the endpoints1.

Tripwire: Tripwire integrates with Cisco ISE through pxGrid to share vulnerability and compliance data of the endpoints. This enables Cisco ISE to apply appropriate network access policies based on the risk and compliance level of the endpoints2.

Splunk: Splunk integrates with Cisco ISE through REST APIs to collect and analyze the logs and events generated by Cisco ISE. This enables Splunk to provide network and security insights, dashboards, reports, and alerts based on the Cisco ISE data3.
