Which two products are involved in granting safe access to apps? (Choose two.)

SD-Access is a campus network fabric solution focused on macro-segmentation and policy-based network automation, not primarily an application access control or identity verification product.

Cisco Duo provides multi-factor authentication and zero-trust device trust checks that verify both user identity and device posture before granting access to applications. This makes Duo a direct control for safe application access, ensuring only authenticated, trusted users on compliant devices can reach protected resources.

TrustSec enforces segmentation policy using Security Group Tags (SGTs) for east-west traffic control across the network, but it does not directly manage or authenticate user access to specific applications.

ACI (Application Centric Infrastructure) is a data center SDN and policy automation solution designed for workload connectivity and microsegmentation, not an identity-driven safe application access product.

Cisco Identity Services Engine (ISE) acts as a centralized policy enforcement point, authenticating users and devices against defined access policies and dynamically granting or denying access to network resources and applications. ISE integrates with Duo and other identity sources to apply consistent, role-based access decisions across the environment.
