SHADOW
IT
The tools you don't know you're using.
Every app a staff member signs up for holds a piece of your business — here's how to see the ones you can't.
01 / What it is
Shadow IT is any app, tool or service used for work without IT's knowledge or approval. It's usually well-intentioned, and that's the trouble: your data ends up in places you can't secure, monitor, or even list.
02 / How it works
1
A staff member hits a limit and signs up for a quick tool.
2
They feed it real data to get the job done.
3
The account — and your data — sit outside your control.
4
A breach or a leaver turns it into an exposure you can't see.
→ You can't protect what you can't see — and you can't even tell a regulator what was lost.
Where it hides
It gathers in the everyday:
File-sharingPersonal cloud drives for work files.
Free SaaS trialsSigned up, never decommissioned.
Automation toolsWired into your real systems.
AI chatbotsCompany data pasted in to 'help'.

Make the right way the easy wayPeople reach for shadow tools when the approved ones are painful. Give them good, sanctioned options and a quick way to request new ones — then nobody needs to go around you. Punishing it just drives it further underground.
03 / Why it's dangerous
- You can't secure what you can't see — or list after a breach.
- Data scatters across unvetted third parties.
- Leavers keep access to tools IT never knew about.
- AI tools can swallow confidential data in a single paste.
04 / How you stop it
- Offer good sanctioned tools so the detour isn't tempting.
- Make requests easy — a fast yes beats a quiet workaround.
- Discover what's in use — expense reports and login logs tell a lot.
- Set a clear AI-use policy on what can and can't be pasted in.
- Review and retire unused accounts regularly.
