Shadow IT

Shadow IT refers to the use of information technology systems, devices, software, applications, and services within an organization without explicit IT department approval. This can range from using unauthorized cloud services like Dropbox or Google Drive, to installing unapproved software on company devices, or setting up personal devices for work purposes without proper security measures.

Shadow IT often arises when employees feel that the officially approved IT tools do not meet their needs, or when they want to use tools they're more familiar with. While it can increase productivity in the short term, it also introduces significant security risks.

Shadow IT is a security risk because it can bypass an organization's security measures, potentially exposing sensitive data or creating vulnerabilities that can be exploited by hackers. The IT department has no visibility into these unauthorized systems, making it impossible to monitor them for security threats or ensure they're properly maintained and updated.

To mitigate the risks of Shadow IT, organizations should implement clear policies about the use of unauthorized IT tools, provide effective, approved alternatives that meet employees' needs, educate employees about the risks associated with Shadow IT, and use security solutions like Cloud Access Security Brokers (CASB) to gain visibility into and control over Shadow IT usage.
