Which three Cisco ISE features were added in release 3.X?

The features introduced in Cisco ISE release 3.X significantly enhance its capabilities and integration with other technologies. Multi-Tenant DNAC is one such important feature, allowing multiple tenants to share the same deployment of Cisco DNA Center. This use case is essential for service providers and large enterprises that require separate administrative environments for different departments or clients while using a single infrastructure.

Having the ability to implement multi-tenancy in management solutions streamlines operations and increases efficiency by enabling businesses to manage multiple entities under one framework without compromising security or data isolation.

While the other features listed—Cisco ISE deployed in the cloud, Azure AD for admin access, and Context Visibility—are indeed significant advancements introduced in this release, multi-tenancy specifically highlights Cisco ISE's flexibility and scalability for larger environments requiring robust user and device management capabilities.
