AI is revolutionizing healthcare. Copilots summarize patient histories, agents streamline triage, and LLMs unlock insights from clinical data. Beneath the innovation, however, lies a growing threat.
AI can scan both structured and unstructured data, including every accessible file, folder, database, and identity. If AI surfaces patient records or trial data where it shouldn’t or gets one line item wrong, it’s game over. Data can’t be unbreached. Ghost users, shadow AI, and missing MFA also help AI form a perfect storm. Without automated data security, healthcare organizations risk more than breaches — they risk lives.
To quantify AI’s impact on the healthcare sector, Varonis produced the State of Data Security Report: Healthcare & Life Sciences. Download the full report and continue reading to learn about the latest risks to health data as you prepare for 2026.
About the report
Our team analyzed data security risks across healthcare, biotech, and pharmaceutical organizations worldwide and found that no organization was breach-proof. In fact, 90% of organizations have exposed sensitive data that can easily be surfaced by AI.
The report examines nearly 1 billion files and explores the data risks associated with AI, cloud environments, and some of the most popular SaaS apps and services, such as Microsoft 365, AWS, Box, Salesforce, and many others.
Below are just a few key findings from our research:
- We found that 64% of organizations have unverified apps, including unsanctioned AI, also known as shadow AI, which increases the risk of exposure and data breaches.
- 86% of companies allow users to create public links. Of those companies, 2,800+ users can create public links.
- Stale accounts remain dangerous after a user’s last login, and 90% of organizations have stale but enabled ghost users in their environments.
- Despite the importance of labeling, only 1 out of 5 healthcare organizations had labeled files.
- 59% of companies have sensitive cloud data exposed to anonymous users.
Alongside these alarming stats, our experts share proactive steps to help secure your critical data throughout the report.
