Shadow AI and permission drift: keeping AI safe after you switch it on 

19 August 2026 

Three EPX IT colleagues talking around a meeting table

Once artificial intelligence is switched on, the job changes from setting it up to keeping it safe. The policy you wrote in month one describes tools your team may have stopped using by month six, permissions drift the way they always have, and the tools themselves change under you. This article is about the part that comes after the rollout: what ongoing AI monitoring actually watches for, and what it produces.

An early-warning system for the AI you have switched on

Shadow AI

Watching for AI tools your staff start using without telling anyone, and for company information heading into them, so a new exposure is caught while it is small. Shadow AI is the norm, not the exception: 62% of UK workers admit to using AI tools their employer has not approved.

Permissions and oversharing

Access drifts over time, and AI makes oversharing visible fast. Keeping an eye on what AI can reach is how it stays what it should reach.

Adoption that pays off

Tracking how the tools you pay for are actually being used, so the spend turns into hours saved rather than idle licences.

Policy that stays current

Your policy and risk register only protect you while they are up to date. They need keeping current as your tools and your team change.

The point is to hear about problems early

Most AI incidents are quiet until they are not: a tool nobody approved, a folder shared too widely, a paste that should never have happened. Monitoring exists to surface those while they are still small and cheap to address, which is the difference between a line in next month's report and a call to your insurer.

One clear report, and a person to talk to

Monitoring is only worth what you do with it, so ours arrives as a branded report each month: the shadow AI we found and what we did about it, how your data exposure and permissions are trending, how adoption is going, and what to address next. It comes with a monthly clinic, so you have a named person to walk you through it and answer what is on your mind.

  • A monthly report you can put in front of your board.
  • A monthly clinic with a senior advisor.
  • Same-day word on the events that matter, so you are never the last to know.
  • A standing record that you are governing AI, not just using it.

Which monthly programme you want depends on your track

There are two, and they are deliberately parallel rather than a sequence. EPX AI Essentials makes the switch-on safe, and its monthly follow-on is AI Managed: Starter, which gives you the visibility on whether the tools you paid for are actually being used. AI Assured is the monthly line on the EPX Intelligence track, for organisations carrying a full AI management system and the assurance obligations that come with it. It runs in three tiers, each adding to the one below, and what each covers and costs is on the EPX Intelligence site.

Either way the monitoring runs on Microsoft Purview and Defender inside your own Microsoft environment, so the signals come from systems you already own. Purview applies at every tier of AI Assured, so we check what you already hold before quoting anything, and your Microsoft licences are always a separate line rather than part of the EPX IT fee.

Where all of this fits in the wider picture is on our AI strategy and implementation service page, and if you want a sense of where you stand first, the two-minute AI readiness quiz is free.
