Shadow IT
Shadow IT
Smartphones and apps that employees use for work without their company's knowledge.
In Simple Terms
Shadow IT refers to IT devices and cloud services that employees use on their own, without getting approval from the company. Examples include using a personally contracted chat app for work communication, or saving company files on a personal smartphone. It's often adopted to make work more efficient, but it's seen as a problem because it creates security risks like data leaks.
Behind the Name
"Shadow" means hidden or out of sight, and "IT" stands for Information Technology. The name comes from how these devices and services are used without ever being noticed or approved by the company or its administrators — quietly staying in the shadows. It's an English-coined term, combining those two words to describe exactly that kind of hidden technology use.
Take a Closer Look!
Shadow IT refers to devices and outside services that employees use for work, even though the company's IT department or administrators don't know about them or haven't approved them.
It often happens because personally owned smartphones, chat tools, and file-sharing services are easier to use than the systems the company officially provides.
In short, it covers any private IT tool that employees use for work without telling the company.
Because this data is handled somewhere administrators can't see, it's more likely to lead to security incidents like data leaks or malware infections — and that's the big problem.
Once an incident happens, it also becomes hard to trace exactly what data leaked and where it went.
Preventing shadow IT takes more than just banning it — companies also need to officially adopt and provide tools that actually fit the way people work.
That's why efforts are underway to understand why employees want to use those tools in the first place, and to build a safe environment where people can still work efficiently.
