Cloud security protects the data, applications, and identities you run in SaaS, PaaS, and IaaS services, across public, private, and hybrid clouds. It covers how your environments are designed and configured, who can access them, and where your data goes.
Cloud providers secure their infrastructure, but your settings, users, and data remain your responsibility. That is where most cloud security risk lives: misconfigured services, stolen credentials, unmanaged apps, and sensitive data shared beyond your control.
