Cisco APIC-EM can verify ACLs. It offers a network-wide simplified approach to manage, deploy, and ensure network policy compliance, including ACL and path verification. Cisco Prime Infrastructure is geared more towards managing infrastructure and performance, especially in wireless environments, while Cisco Wireless LAN Controller is focused on wireless network management. Cisco IOS-XE is an operating system for Cisco devices, but it doesn't offer the same centralized verification functionality as APIC-EM.
