Surge in Cloud Adoption Means a Greater Data Attack Surface for Healthcare and Financial Services

AUSTIN and LONDON – March 8, 2023—New research launched today by Blancco Technology Group (LON: BLTG), the industry standard in data erasure and mobile lifecycle solutions, reveals the extent to which healthcare and financial services organizations have embraced cloud, as well as the effects cloud adoption has had on data classification, minimization and end-of-life (EOL) data disposal.

Based on a global survey of 1,800 respondents, the study, Data at a Distance, found extensive cloud adoption, thanks to the ease of managing increasing volumes of data. However, 65% say the switch has increased the volume of redundant, obsolete or trivial (ROT) data they collect.

Increasing volumes of stored data brings with it many issues and is of growing concern for organizations operating in heavily regulated markets. In addition to regulatory noncompliance risks, there are the cost and sustainability impacts of storing this data, as well as security concerns—more data means a greater attack surface and more liability in case of a breach.

Data management best practices indicate that organizations need to know what data they have collected, including its value, where it’s stored and when it needs to be permanently erased. Yet just over half of organizations (55%)can boast a mature data classification model that determines when data has reached EOL—meaning that nearly half fall short when it comes to determining when to dispose of cloud-stored data.

When asked about their cloud approaches, 60% of respondents said that their cloud provider handles EOL data for them. However, more
