Healthcare Data is moving fast and the results are measurable. With the global analytics market set to reach USD 104.41 billion by 2032 and healthcare data breaches exposing 51.2 million patient records in the U.S. in 2022, the promise of smarter care comes with a sharper security test. The gap between clinical gains like 94% breast cancer detection and operational strains like 277 days to identify and contain a breach is exactly where these statistics get interesting.
