What is Shadow IT?

2 min read

Shadow IT refers to technology—particularly software and cloud services—used within an organisation without IT department knowledge or approval. This includes SaaS applications purchased on corporate credit cards, AI tools accessed with work accounts, and cloud services spun up by business units to solve immediate problems. While Shadow IT often emerges from legitimate business needs, it creates significant risks around security, compliance, and wasted spending.
