Shadow IT
Shadow IT is the use of apps and services by employees, teams, or departments without the knowledge, oversight and, ultimately, control of your organization. Shadow IT in the form of SaaS applications is an ongoing, perpetual challenge for security professionals. The core problem is often unenforced security policies on an enterprise level. If system-wide best practices are established and enforced, the risk can be contained, dramatically reducing security vulnerabilities.
Cloud sprawl
Cloud sprawl is the uncontrolled proliferation of your organization's cloud instances, services, or providers, oftentimes without your company's knowledge or oversight. Sprawl happens when organizations fail to properly monitor, manage, or control their cloud environment.
