Legal Framework for security risks in the UK
The UK’s cyber threat liability landscape is shaped by the UK GDPR and the new Data (Use and Access) Act 2025.
Key GDPR obligations:
-
Report data breaches to the ICO within 72 hours.
-
Face fines up to 4% of global turnover or £17.5 million.
-
Notify affected individuals if there’s a high risk of harm.
Fines are no longer theoretical Marriott paid £18.4 million after a major breach.

Data (Use and Access) Act 2025 and Cyber Threat Liability
The new law modifies but also strengthens some aspects of cyber threat liability:
-
Marketing data breaches now carry higher penalties.
-
Companies must manage complaints more effectively.
-
Automated decision-making has expanded, but users can appeal.
Failing to adapt could leave your company exposed to legal action.
Victim Compensation Under Cyber Threat Liability
Data breach victims can now sue for:
-
Financial losses (fraud, stolen funds)
-
Non-financial harm (stress, reputational damage)
Courts consider:
-
The sensitivity of data (e.g., medical vs. email)
-
The measures you took to protect it
Without strong security steps like encryption, your defence weakens.
Financial Impact of Cyber Threat Liability
The average breach costs UK businesses £1,600, but fraud-related cases average £5,900. Add downtime, customer loss, and share price drops, and the long-term damage can be catastrophic.
Examples:
-
EasyJet: Data breach affecting 9 million customers lawsuits & investigations.
-
Toyota: Factory shutdowns after cyber attack global production delays.
Emerging Risks Intensifying Cyber Threat Liability
Future attacks are evolving:
-
AI-powered phishing makes fake emails and calls more convincing.
-
Voice cloning targets executives for fraudulent transfers.
-
Supply chain hacks exploit smaller partners to reach big firms.
Cyber criminals now exploit the weakest link which could be your vendor, not you.
Best Practices to Reduce Cyber Threat Liability

Why Ignoring Cyber Threat Liability is a Business Risk
Failing to prepare for security risks can sink a business. Regulatory fines, lawsuits, and loss of customer trust often cost more than prevention measures.
