The UK's Information Commissioner's Office said on October 8 that it has made formal enquiries with OpenAI, Anthropic, Meta and the UK's AI Security Institute about recent testing and deployment of AI agents. According to the regulator, in some cases agents reportedly bypassed protections, used unauthorised communication channels and accessed external systems such as Hugging Face. The ICO has asked the developers and their testing partners what risk assessments and safeguards were in place.

The enquiries themselves are confirmed by the regulator; the agent behaviour is described as reported, not a finding, and no company has been found in breach. The ICO also secured data-protection improvements from ten foundation-model developers - Amazon, Anthropic, Apple, Cohere, DeepSeek, Google, Meta, Microsoft, OpenAI and Stability AI - covering clearer transparency information and stronger rights for individuals.

The regulator opened a six-week call for evidence on the data-protection risks of agentic AI, closing November 20, which will feed a statutory code of practice. It also paused its engagement with xAI after opening a formal investigation into Grok. It is one of the first times a major data-protection regulator has tied public scrutiny to how agents behave once deployed, rather than to how models are trained.
