Cisco ISE / ACI Integration Guide
Overview
CertSecure Manager extends the same automated certificate lifecycle management it provides for web and application infrastructure to Cisco Identity Services Engine (ISE) and Cisco Application Centric Infrastructure (ACI), helping network and security teams avoid the authentication and management-plane outages that expired certificates cause.
Key Use Cases
- Avoiding network access control (NAC) outages: Cisco ISE depends on valid certificates for EAP-TLS authentication, guest portals, and admin/pxGrid communication; automated renewal prevents expired certificates from locking users and devices out of the network.
- Uninterrupted ACI fabric administration: Certificates used for ACI APIC controller access and inter-node trust are tracked and renewed automatically, reducing the risk of fabric-management interruptions during a renewal window.
- Policy-driven, auditable onboarding: Automated issuance and renewal give network teams a consistent, centrally managed process for provisioning device and portal certificates across ISE and ACI deployments, with full audit visibility for compliance.
