Which is a security product that was covered in the Policy and access security module?

Cisco NFGW is not a recognized Cisco product name, and no product by this designation belongs to the policy and access security domain.

Cisco ISE is the central product in Cisco's policy and access security domain, providing network access control (NAC), 802.1X authentication, and granular role-based policy enforcement across wired, wireless, and VPN connections. It integrates with Active Directory and other identity stores to authenticate users and devices before granting network access, enforcing least-privilege segmentation. These capabilities place ISE squarely within the Policy and Access Security curriculum module.

Cisco NGIPS is a Next-Generation Intrusion Prevention System focused on detecting and blocking network-based exploits and threats, which places it in the threat defense domain rather than policy and access security.

Cisco Defense Orchestrator is a cloud-based management platform for consistent firewall policy across Cisco security devices, and is categorized under firewall management rather than identity-based access control.
