5 Key cybersecurity laws every UK business must follow

Cybersecurity is a growing concern for UK businesses, with cyberattacks and data breaches becoming more frequent and costly. To address these risks, the UK government has established several key regulations that businesses must follow to protect sensitive data and ensure compliance. Failing to adhere to these laws can result in hefty fines, reputational damage, and even legal action.

1. General Data Protection Regulation (GDPR)

As one of the most comprehensive data protection laws, GDPR governs how organisations collect, process, and store personal data. Non-compliance can result in fines of up to £17.5 million or 4% of global turnover, whichever is higher.

Key requirement: Businesses must obtain explicit consent to process personal data and ensure robust data security measures are in place.

2. Network and Information Systems (NIS) Regulations

The NIS regulations aim to improve cybersecurity for businesses in critical industries like energy, healthcare, and transport. These laws require companies to implement security measures and report incidents promptly.

Key requirement: Organisations must identify and manage risks to their network infrastructure and notify the Information Commissioner’s Office (ICO) of any significant incidents.

3. Data Protection Act 2018

This law supplements GDPR and sets additional requirements specific to the UK. It addresses how personal data can be processed, particularly in relation to law enforcement and public authorities.

Key requirement: Ensure compliance with both GDPR and the specific provisions of the Data Protection Act 2018.

4. Payment Card Industry Data Security Standard (PCI DSS)

For businesses that handle card payments, PCI DSS compliance is crucial. It sets requirements to secure cardholder data and protect against fraud.

Key requirement: Encrypt payment data, maintain secure networks, and monitor all access to sensitive information.

5. Computer Misuse Act 1990

While primarily focused on criminal activity, this act also impacts businesses by outlining what constitutes unauthorised access to systems and data. It is essential for companies to safeguard their networks against unauthorised use.

Key requirement: Implement strict access controls and monitor system activity to prevent misuse.
