Unapproved and agentic AI: the risk inside your own organisation

The NCSC warns that staff using unapproved AI services can expose sensitive information, and that agentic AI adds risk through the access it holds.

The warning

Two separate risks

Alongside the threat from attackers, the NCSC highlights risks from an organisation's own AI adoption.

Unapproved services

The review warns that employees using unapproved AI services can expose sensitive company information and leave the employer unable to track how that data is handled [7]. The NCSC's frontier AI guidance asks organisations to understand why staff use unapproved tools in the first place [5].

Agentic AI

Agentic AI can plan, decide and act on a user's behalf, which adds risk especially around the access it has to systems and data [5]. The NCSC asks organisations to understand how such tools are used and what access they hold [5].

Steps

A first pass

  1. 1

    Ask staff and teams which AI tools they use, without blame, and note why.
  2. 2

    Provide approved alternatives where the unapproved tool meets a real need [5].
  3. 3

    For agentic tools, list what systems and data each can reach and remove what it does not need.
  4. 4

    Apply safeguards, sandboxing and active human oversight [5].

Defence

AI on your side

The NCSC believes AI will ultimately be a net positive for cyber security, and advises adopting it carefully to strengthen defences [5]. Reporting of the review adds that automated defensive actions need clear limits and human oversight to avoid disruption [7].

A useful rule is to treat an AI tool like any other supplier or user account: it needs an owner, a defined purpose and the least access that lets it work. The NCSC's guidance asks you to know what access such tools hold [5].

Why oversight matters

The NCSC acknowledges that automated defensive activity currently sits outside many organisations' risk tolerances [9].

How CyPro can help
