The Cyber Security Breaches Survey, 2019 was run to understand organisations' approaches and attitudes to cyber security, and to understand their experience of cyber security breaches. Its aim was to support the Government by providing evidence that can inform policies which help to make Britain a safer place to do business online.

The data have been collected annually since 2016 to understand the views of UK organisations on cyber security. Data is collected on topics including online use; attitudes of organisations to cyber security and awareness of Government initiatives; approaches to cyber security (including investment and processes); incidences and impact of a cyber security breach or attack; and how breaches are dealt with by the organisation. This information helps to inform Government policy towards organisations, including how best to target key messages to businesses and charities so that they are cyber secure (and so that the UK is the safest place in the world to do business online). Please note that the UK Data Service only holds data from 2018 onwards.

The underlying data are useful for researchers to better understand the response across a range of organisations (rather than averages) and for wider comparability over time. The survey originally only covered businesses but was expanded to include charities from the 2018 survey onwards.
