Your SME doesn’t build AI, but it desperately needs an AI security strategy

The reality is that your team is likely already using AI. Whether it’s drafting emails in ChatGPT, summarising meetings with Otter.ai, or generating images in MidJourney, Shadow AI has already entered your building.

Without a strategy, your proprietary data, customer privacy, and brand reputation are at risk.

Here is how to move from "reactive" to "secure" in 90 days, including a template to get your internal policy started.The 90-Day SME RoadmapYou don’t need a massive IT department to secure your AI usage. You just need a phased approach:

• Phase 1 (Days 1–30): Visibility. Audit your team. Find out which tools they are using and what data they are inputting. Awareness is the first line of defence.
• Phase 2 (Days 31–60): Controls. Move your team away from "Free" consumer versions of AI to "Enterprise" versions (like Microsoft Copilot for Business). These versions generally guarantee that your data won't be used to train public models.
• Phase 3 (Days 61–90): Ownership. Assign an "AI Lead"—this doesn't have to be a coder; it just needs to be someone responsible for keeping the tool list updated and the policy enforced.

Starting Today: Your Internal AI Usage PolicyTo help our peers navigate this, we’ve developed a "plug-and-play" policy template. If your SME doesn't have one yet, feel free to adapt the following:

[COMPANY NAME] Acceptable Use Policy: Generative AI

1. Purpose
This policy provides a framework for the safe and ethical use of Generative AI at [COMPANY NAME]. Our goal is to embrace innovation while protecting our intellectual property.

2. Approved Tool Registry
Employees may only use AI tools vetted by [DEPARTMENT/ROLE].

Sanctioned Tools: [LIST APPROVED TOOLS]

Prohibited Tools: [LIST BANNED TOOLS]

3. Data Sensitivity (The Golden Rule)
Never input PII (names/emails), financial data, or trade secrets into any AI tool unless it is a [COMPANY NAME]-governed enterprise instance.

4. Human-in-the-Loop
AI can "hallucinate" (state falsehoods). You are 100% responsible for the accuracy of any output. All AI-generated content must be reviewed by a human before being sent to a client.

5. Disclosure
If AI is used to create a significant portion of a deliverable, include: “Parts of this document were drafted with the assistance of AI and verified by [COMPANY NAME] staff.”

The Bottom LineAI security for an SME isn't about building firewalls around a model; it's about governance and habits. By setting clear boundaries now, you ensure that AI remains a powerful assistant rather than a liability.
