    NCSC AI Guidance and Cyber Essentials Scope: Copilot, ChatGPT, Shadow AI

    Published 10 July 2026

    The three categories of AI tool

    • Embedded AI – Microsoft 365 Copilot, Google Workspace Gemini. Inherits tenant identity and data controls.
    • Enterprise SaaS AI – ChatGPT Enterprise, Claude Teams, Glean. A SaaS app in scope like any other.
    • Shadow AI – staff using consumer accounts (free ChatGPT, free Claude) with work data. Out of your control by default.

    Embedded AI (Copilot, Gemini)

    Because Copilot runs inside your Microsoft 365 tenant, it inherits Conditional Access, MFA and DLP. The CE/Danzell scope question is the same as for the underlying tenant. Make sure SharePoint and OneDrive permissions are tight – Copilot will surface whatever the user can already see, and over-permissive sites become an instant data leak.

    Enterprise SaaS AI (ChatGPT Enterprise et al.)

    Treat exactly like any other SaaS app:

    • SSO from your identity provider (Entra ID, Okta, Google).
    • MFA enforced via the IdP.
    • Admin console MFA – see Danzell MFA guide.
    • Data retention and training-opt-out configured at tenant level.
    • Listed in your scope as an in-scope cloud service (SaaS).

    Shadow AI: the real risk

    A staff member pasting client data into free ChatGPT is the most common AI incident UK assessors flag. Practical controls:

    • Acceptable use policy that names AI tools explicitly.
    • Provide a sanctioned AI tool so staff have a safe alternative.
    • Browser-side controls or DLP for high-risk roles.
    • Identify and block consumer AI domains where the risk justifies it.

    NCSC guidance in one paragraph

    NCSC's position is consistent with its wider guidance: understand where your data goes, control identity and access, monitor for misuse, and treat AI providers like any other third-party processor. Nothing in Cyber Essentials requires you to avoid AI – it requires you to bring AI tools into scope properly.
