Data Protection Basics for Businesses Handling Personal Data
A plain-English guide to core data protection principles for businesses handling personal data: lawful basis, minimisation, security and retention.
Generative AI assistants, writing tools, code helpers and meeting summarisers have moved from novelty to everyday workplace software remarkably quickly. In many organisations, staff started using them before anyone in management had decided whether they should. That is understandable, because the tools are genuinely useful, but it also means that sensitive information may already be flowing into services nobody has assessed. Good governance is not about banning AI. It is about deciding deliberately which tools are allowed, for what purposes, with which data, and under whose oversight. This article sets out a practical, proportionate approach that a small or medium-sized business can put in place without a dedicated compliance department.
AI tools differ from most business software in a few important ways. They accept free-text input, so it is easy for an employee to paste in a customer email, a contract clause or a spreadsheet of personal data without thinking. Their output can be confident and fluent while still being wrong. And the terms under which providers process, retain or learn from submitted content vary considerably between consumer and business editions of what appears to be the same product.
The main risks a business should weigh are:
None of these is a reason to avoid AI altogether. They are reasons to manage it in the same way you would manage any other system that touches business data.
Before writing a policy, find out what is already happening. A short, non-judgemental survey of staff often reveals more tools than expected: browser extensions, transcription bots joining video calls, AI features switched on inside existing software, and free accounts on public chat services. Your IT provider can supplement this by reviewing sign-in logs, browser extension inventories and third-party application consents in your identity platform.
Record each tool, who uses it, what for, and what kind of data goes into it. This inventory becomes the starting point for decisions and should be kept up to date.
Most AI policies fail because they are vague. Telling staff to "use AI responsibly" gives them nothing to act on. A simpler approach is to link AI use to a basic data classification scheme that people can remember. For example:
| Data class | Examples | Permitted AI use |
|---|---|---|
| Public | Published marketing copy, public web content | Any approved tool |
| Internal | Internal process notes, draft non-sensitive documents | Approved business-tier tools only |
| Confidential | Client contracts, financials, unreleased product plans | Only tools with contractual data protections, and only for named use cases |
| Restricted | Personal data of customers or staff, health data, credentials | Not permitted unless specifically assessed and approved |
Adjust the categories to suit your business, but keep the number small. Staff should be able to decide in seconds which class a piece of information belongs to.
For each AI tool you consider, ask the same questions you would ask of any supplier, plus a few specific to AI:
Maintain a short list of approved tools and make it easy to find. Equally important, give staff a simple route to request a new tool. If the approval process is slow or opaque, people will quietly work around it.
An effective acceptable-use policy for AI can usually fit on two pages. It should cover:
Write it in plain language and include a few worked examples. "Summarising a public industry report: fine. Pasting a customer complaint containing names and addresses into a free chatbot: not permitted." Concrete examples do more than paragraphs of principle.
Assign an owner for AI governance. In a small business this may be an operations manager working with the IT provider; in a larger one it may be a small steering group including IT, legal or compliance, and a business representative. Their responsibilities include maintaining the approved tool list, reviewing new requests, tracking changes to provider terms, and handling incidents.
For higher-risk use cases, such as anything affecting customers' rights or employees' careers, require a brief documented assessment before rollout. Note what the tool does, what data it uses, what could go wrong, how errors will be detected, and who signs off. This need not be bureaucratic; a one-page template is usually enough.
Training should be practical. Show staff how to write effective prompts, how to spot fabricated references or figures, and why verification matters. Explain the reasoning behind the data rules rather than only stating them; people follow rules they understand.
Governance is not a one-off project. Providers change their terms, add features and release new models frequently. Schedule a review of the approved tool list and policy at least every six months, and whenever a major new tool or feature is introduced. Use the review to ask staff what is working, what is frustrating, and what they wish they could do.
Responsible AI adoption is mostly good IT governance applied to a new category of tool. Know what is being used, decide what data can go where, choose providers whose terms you understand, keep a human accountable for output, and revisit your decisions regularly. Businesses that put these foundations in place tend to get more value from AI, not less, because staff can use approved tools confidently instead of nervously or in secret. Start with the inventory and the data rules this month; the rest can follow in stages.
