An organization wants to secure users, data, and applications in the cloud. The solution must be API-based on operate as a cloud-native CASB. Which solution must be used for this implementation?

Cisco Firepower Next-Generation Firewall is a network security appliance, not an API-based cloud-native CASB.

Cisco Cloud Email Security focuses on protecting email, not securing general cloud applications and data as a CASB.

Cisco Umbrella provides DNS-layer security and secure web gateway capabilities, but it is not specifically an API-based, cloud-native CASB.

Cisco Cloudlock is a Cloud Access Security Broker (CASB) that operates as a cloud-native, API-based solution. It provides visibility, threat detection, and data security across cloud applications by integrating directly with cloud service providers via APIs, without requiring agents or proxies.
