Which Cisco security solution secures public, private, hybrid, and community clouds?

Cisco ISE (Identity Services Engine) is primarily an on-premises access control system that manages authentication, authorization, and accounting for network access, not a cloud security broker for various cloud types.

Cisco ASAv (Adaptive Security Virtual Appliance) is a virtual firewall that can be deployed in cloud environments to secure specific segments, but it's a firewall, not a comprehensive cloud security solution for all cloud types and aspects like data governance or CASB.

Cisco Cloudlock is a Cloud Access Security Broker (CASB) that discovers and monitors user and data activity, detects threats, and enforces policies across SaaS, PaaS, and IaaS environments, making it suitable for securing all types of cloud deployments (public, private, hybrid, community).

Cisco pxGrid (Platform Exchange Grid) is an integration framework for sharing contextual security information between different security products, not a standalone cloud security solution.
