AI and cyber security in the UK: legal duties, risk management, compliance measures and contractual considerations under UK GDPR, NIS and related regimes

Published by a LexisNexis Information Law expert

Practice notes

This Practice Note outlines the principal cybersecurity ramifications posed by artificial intelligence (AI) in relation to duties under UK law, including those arising from the United Kingdom General Data Protection Regulation, Assimilated Regulation (EU) 2016/679 (UK GDPR). It further sets out practical guidance on embedding AI as a relevant factor within existing cybersecurity compliance frameworks already in place. Advances in AI prompt concerns about the implications for cybersecurity and, as adoption grows, so too do related cybersecurity concerns.

In January 2024, the UK National Cyber Security Centre (NCSC), the UK’s technical authority on cyber threats, warned that AI will almost certainly render cyberattacks on UK organisations more effective and widespread. In April 2026, DSIT and the Cabinet Office published an open letter to businesses on AI cyber threats, warning that the development of AI models is dramatically expanding the speed and scale at which cyber attacks are being carried out, and that organisations must adjust the way they manage cyber risk accordingly in response (see: LNB News 16/04/2026 14).

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
