If your business uses ChatGPT, Microsoft Copilot, Google Gemini, or any AI-powered tool — you already have an AI governance problem. You may just not know it yet.
This isn't a scare piece. It's a practical guide for SMEs to understand what risks exist and what minimum steps to take.
What "AI governance" actually means for a small business
Governance sounds like a large-company concept. It isn't. For an SME, AI governance means three things:
- Knowing which AI tools your staff are using (you probably don't know all of them)
- Understanding what data those tools are processing (often more than you think)
- Having basic rules about how AI can and can't be used (most businesses have none)
That's the foundation. Everything else builds from there.
The real risks your SME faces
Data leakage
When a staff member pastes a client contract into ChatGPT for summarisation, that data is sent to OpenAI's servers. Depending on your subscription type and the tool's data retention settings, that data may be used for model training.
For businesses handling personal data, this is a potential UK GDPR breach. For businesses with confidentiality obligations (legal firms, accountants, healthcare), this could violate professional duties.
Shadow AI
Your IT policy almost certainly doesn't mention AI tools. That means staff are using them without oversight, often with the best intentions — saving time, improving their work. But without visibility, you have no idea what data is leaving your organisation.
A survey by Cyberhaven in early 2024 found that 11% of data employees paste into ChatGPT is classified as confidential.
AI-generated code and security
Development teams increasingly use GitHub Copilot and similar tools to generate code. AI-generated code introduces a specific category of vulnerability: the model suggests code based on patterns in its training data, which includes vulnerable code. Studies have found that a significant proportion of AI-suggested code contains security weaknesses.
Vendor AI embedded in existing tools
Microsoft 365 Copilot, Salesforce Einstein, HubSpot AI — these are embedding AI into tools you already use. The data processing implications often aren't clearly explained in default configurations.
What to implement: a minimum viable AI governance framework
1. Audit what's being used
Start with a simple survey to your team: What AI tools are you using for work? You'll be surprised by the answers.
Also check your SaaS tools for AI features that may have been enabled by default.
2. Classify your data
Not all data carries the same risk. Create a basic classification:
- Public — marketing materials, published content
- Internal — operational documents, internal communications
- Confidential — client data, contracts, financial records, personal data
Then create a rule: confidential data should not be entered into external AI tools without explicit approval.
3. Write an AI Acceptable Use Policy
One page. Not a legal document. It should answer:
- Which AI tools are approved for work use?
- What data categories can be processed by AI?
- Who do you contact if you're unsure?
- What to do if you accidentally share something sensitive?
4. Configure your AI tools properly
For Microsoft Copilot: review your data processing settings in the Microsoft 365 Admin Centre. Ensure tenant data isolation is configured correctly.
For ChatGPT: if using the Teams plan, confirm data is not used for model training (this requires an explicit opt-out in Enterprise, and isn't the default on free tiers).
5. Review AI-generated code before merging
If developers are using Copilot or similar: implement a code review policy that specifically includes security review of AI-generated sections.
The regulatory direction of travel
The EU AI Act is now in force. The UK has taken a principles-based approach rather than prescriptive legislation, but the direction is clear — AI risk management will become a compliance obligation.
Businesses that build governance practices now will be ahead of the curve when formal requirements arrive.
