In today's borderless enterprise environments, identity-based access control is only as strong as its weakest integration point. This guide moves beyond basic configuration steps to deliver the strategic reasoning behind design decisions, scaling, and policy structure. Grounded in years of real-world experience, it equips you to design, deploy, and troubleshoot Cisco Identity Services Engine (ISE) from small campus environments to massive multi-site architectures.

Key Topics Covered:

• Hybrid & Cloud Deployments: Master core ISE deployment principles, sizing, high availability, and cloud models across AWS, Azure, and OCI.
• Advanced Policy Sets: Structure authentication and authorization options, including certificate-based access, MFA, and external identity sources.
• Micro-Segmentation & TrustSec: Implement Cisco TrustSec across campus networks, WAN/SD-WAN, and data center policy interconnects.
• Device Profiling and Posture: Leverage Multi-Factor Classification, Cloud MFC Profiling, guest access, and posture services.
• Ecosystem Integration: Extend consistent, identity-driven policy across Meraki environments with Meraki Adaptive Policy, remote access, SSE, and multicloud workloads.

Whether you are securing traditional on-premises networks or complex hybrid infrastructures, this book provides the expert-level knowledge required to enforce consistent Zero Trust policy everywhere
