For most CIOs, shadow IT stopped being a surprise years ago. You know there are more apps, plugins, and cloud services in use than appear on any official architecture slide. Now a new variant has arrived: shadow AI. Employees are pasting sensitive content into public models, connecting unapproved AI assistants to SaaS tools, and relying on outputs you can’t easily see or govern.
The risk is obvious: data leakage, compliance breaches, brittle processes that depend on tools you don’t control. Less obvious, but just as important, is the risk of over-correcting. If your response is to block aggressively without improving how people use sanctioned platforms like Microsoft 365, Salesforce, Workday, and Copilot, you will strangle innovation and push workarounds out of sight.
This article argues for a different path. It’s written for CIOs, IT Directors, Heads of Transformation, and Application Owners who need to manage shadow IT and shadow AI as part of a broader digital workplace strategy. We’ll look at how these phenomena are linked, why they are fundamentally adoption and experience problems, and how to use governance plus a Digital Adoption Platform (DAP) like Lemon Learning to keep risk in check while still giving the business room to move.
From shadow IT to shadow AI: same drivers, new stakes
Shadow IT came first: unsanctioned SaaS, personal cloud storage, team-level tools bypassing IT. As vendors like Valence and Wing Security have documented, shadow IT thrives when official tools are hard to access, slow to change, or poorly adopted. Employees do not wake up wanting to break policy; they want an easier way to share files, manage projects, or analyse data.
Shadow AI builds on the same pattern but raises the stakes. Instead of bringing in a standalone app, employees can now summon AI assistants directly inside tools they already use, browsers, messaging apps, productivity suites. The shift from shadow IT to shadow AI, makes AI adoption faster, harder to see, and more tightly coupled to real work.
The consequences go beyond licence waste or fragmented data. Shadow AI can quietly shape the emails you send to customers, the analysis that underpins financial decisions, the code that ships to production, or the summaries that reach your board. When this happens in tools you don’t control, or with models that learn from your prompts, you inherit risk without visibility.
Yet the demand is not going away. McKinsey and others report that a large majority of organisations now use AI in at least one business function. If you block every route, employees will consume AI via their phones or personal accounts. The challenge is not whether AI and unsanctioned SaaS will exist; it is whether you will have a way to see, steer, and support how they are used.
That brings us back to adoption. People turn to shadow IT and shadow AI because they are trying to do something your official stack doesn’t support well enough today, prepare a client deck, summarise a complex case, get through approvals faster. If your governance strategy ignores that reality, it will fail. If you pair controls with serious investment in digital adoption, making it easier to use Salesforce, Workday, Microsoft 365, Copilot, ERP, and HRIS correctly, you have a chance to shrink the shadows without turning off the lights.
Designing guardrails and enablement for shadow IT and shadow AI
The instinctive response to shadow anything, IT or AI is to clamp down. Block domains, lock app stores, tighten firewalls. In the short term, this may reduce visible risk. In the medium term, it usually pushes experimentation further underground and makes your sanctioned stack look even less attractive. The better path is to set guardrails that are clear, enforceable, and paired with viable alternatives.
Start with policy, but keep it human. A five page AI and SaaS policy PDF will not change behaviour in the moment someone is trying to hit a deadline. You need a one-page version for employees: what they can use, what they must avoid, and how to request exceptions.
Then, embed those examples where people work. This is where a Digital Adoption Platform such as Lemon Learning becomes part of your governance toolkit, not just a training aid. You can overlay Microsoft 365, Salesforce, Workday, SAP, and internal portals with short, contextual messages and walkthroughs that express your rules in plain language at the moment of risk.
For instance, when a user installs a new SaaS integration from within Microsoft 365, you can show an in-app prompt explaining your approval process and linking to a secure catalogue of vetted tools. When someone opens Copilot in Outlook or Teams for the first time, a short guide can introduce your AI dos and don’ts, with examples of safe and unsafe prompts. When a manager is about to export data from Salesforce to a personal spreadsheet, a tooltip can remind them of your data residency rules and offer an approved reporting option.
On the IT side, pair these behavioural nudges with technical controls. Identity and access management, SaaS discovery, and security posture management tools remain essential. Wing Security’s guide to managing SaaS shadow IT outlines the basics: continuous discovery, risk scoring, and automated remediation. Your job is to ensure that where you do restrict usage, there is an equivalent or better experience waiting in the sanctioned environment supported by in-app guidance that makes the transition survivable for users.
Finally, treat innovation as something to channel, not suppress. Create safe sandboxes where teams can trial new SaaS and AI tools under controlled conditions, with clear time limits and data boundaries. Use Lemon Learning to document and guide those experiments: short guides explaining the scope, expected behaviours, and exit criteria. If an experiment proves valuable, you already have usage patterns and early guidance to feed into a formal onboarding and adoption plan.
