Which Cisco solution falls under cloud security?

Cisco Umbrella is a cloud-native security service that protects users from threats at the DNS layer before a connection is established, operating entirely from Cisco's global cloud infrastructure. It provides cloud-delivered functions including Secure Web Gateway, CASB, and DNS-layer security. Because it is built and delivered as a cloud service rather than a physical appliance or on-premises software, it is the defining Cloud Security product in Cisco's portfolio.

Identity Services Engine (ISE) is an on-premises network access control and policy management solution, not a cloud security platform.

Firepower Threat Defense (FTD) is Cisco's next-generation firewall and IPS software running on physical or virtual appliances, categorized under Network Security rather than Cloud Security.

Cisco Defense Orchestrator (CDO) is a cloud-based management tool used to manage Cisco security devices, making it a management platform rather than a cloud security enforcement product.
