Shadow IT is the use of software, applications, or technology systems within an organization that bypasses approval, monitoring, and governance by IT teams. While it often stems from employees trying to improve productivity, Shadow IT creates significant security risks, such as data breaches, compliance violations, and unmanaged access. These tools may lack proper encryption, authentication, or compliance with company policies, leaving sensitive information vulnerable. Organizations must adopt tools and practices, such as Cloud Access Security Brokers and SaaS management platforms, to discover and manage Shadow IT effectively.
