A company is experiencing exfiltration of credit card numbers that are not being stored on- premise. The company needs to be able to protect sensitive data throughout the full environment. Which tool

Cisco Security Manager is primarily a management platform for Cisco network security devices (e.g., firewalls), not a cloud-native DLP solution.

Cisco Cloudlock is a Cloud Access Security Broker (CASB) solution that provides data loss prevention (DLP) capabilities specifically designed for cloud applications and environments. It detects and prevents exfiltration of sensitive data like credit card numbers across various cloud services, thereby protecting data not stored on-premise.

A Web Security Appliance (WSA) primarily protects against web-based threats and controls web access, but it is not designed for comprehensive cloud DLP across various SaaS applications.

Cisco Identity Services Engine (ISE) is used for network access control (NAC) and policy enforcement for devices connecting to the network, not for preventing data exfiltration in cloud applications.
