UK Data Residency: Which AI Security Vendors Offer It?

A review of public vendor materials dated 1 October 2026 found that few AI security providers clearly document UK-hosted regions for AI-specific services, although Microsoft, Wiz, Cloudflare, Netskope and Mindgard describe some UK-related infrastructure or platform options whose AI coverage remains uncertain. Several vendors, including Cisco, Check Point’s Lakera, Pillar, SentinelOne, Noma and NeuralTrust, offer self-hosted or customer-environment deployments that can keep data under an organisation’s control, while Palo Alto Networks, CrowdStrike, Zscaler, Zenity and HiddenLayer did not publicly identify UK regions in the reviewed pages. UK GDPR does not generally require data to be stored in the UK; instead, it regulates restricted international transfers and permits them through adequacy decisions, safeguards such as the IDTA or UK Addendum, or limited derogations. The guide notes changes from the Data (Use and Access) Act 2025, continuing UK-EU adequacy, and the conditional UK-US Data Bridge, while stressing that sector-specific rules and contracts can impose further requirements. Organisations are advised to obtain written, product-specific information on where prompts, outputs, logs, telemetry, embeddings, support access and subprocessors are located, then incorporate those flows into transfer risk assessments. It also argues that residency is only one part of AI security, since controls against risks such as prompt injection, data leakage and unsafe agent tool access remain necessary regardless of hosting location.
