Explanation
Cisco Umbrella is a cloud-delivered security platform that operates at the DNS layer. When a device makes a DNS query, Umbrella inspects the request and blocks resolution of domains associated with malware, phishing, ransomware, or other threats - before any connection is ever established. This makes it effective for filtering malicious content and enforcing acceptable-use policies across the network. Cisco ASA Firepower is a next-generation firewall/IPS appliance. Cisco AMP (Advanced Malware Protection) focuses on endpoint malware detection and response. Cisco ISE (Identity Services Engine) handles network access control and policy enforcement - none of these operate primarily at the DNS layer.
