Healthcare providers hold some of the most sensitive information a person can share - their medical history. The most recent data shows Australian healthcare service providers accounting for nearly 20% of total data breaches in 2025 (according to Australia’s OAIC data). We’ve seen many breaches, including this latest one that has recently affected one of Australia’s leading healthcare providers.
It’s no surprise that healthcare data is a target. Health records are a rich target: identity details, financial information, medical history, prescriptions, insurance data and sometimes even family information. On the dark web, full medical records can sell for 10–20 times more than stolen credit card numbers because they enable long‑term fraud, identity theft and extortion.
For many healthcare organisations, electronic health records, telehealth, remote access, AI scribe tools, and cloud migrations have increased the amount of data stored, often growing faster than cybersecurity budgets or staffing. Attackers exploit this gap.
Understand where your data is
Data volumes are exploding, and traditional tools like data flow diagrams only show where information should be - not where it actually ends up. Ground Labs research found that 42% of businesses don’t know where all their sensitive data is stored. That gap fuels compliance drift: when policies and controls stay static while data spreads into systems governed by different rules.
Across the Australian Privacy Act, GDPR, HIPAA and PCI DSS, drift often looks like:
These small, often overlooked data stores tend to be the most exposed, with weaker controls and overly permissive access.
Closing the gap with data intelligence
Data intelligence uncovers the exceptions - the hidden, duplicated and misplaced data created through everyday business operations. Once identified, organisations can delete unnecessary data, tighten controls or bring new locations under governance.
I’ve found that tools such as Ground Labs Enterprise Recon provides this visibility across structured and unstructured sources, on‑premises, cloud and hybrid environments. It aligns sensitive healthcare data to regulatory requirements, highlights concentrations and exposures, and supports continuous scanning to show where data appears, moves or accumulates over time.
A more resilient compliance posture
As healthcare providers continue to digitise their operations, the need for effective data discovery, risk management and governance solutions becomes increasingly critical. The Australian Privacy Act, GDPR, HIPAA and PCI DSS all rely on an accurate understanding of the data being governed. As data moves through SaaS platforms, cloud services, user workflows and legacy systems, that understanding becomes harder to maintain and compliance drift grows.
Data intelligence helps organisations shift from periodic compliance exercises to a persistent state of readiness. With intelligent scanning tools, businesses can gain a real‑time view of protected health data and cardholder data, strengthening your compliance and enabling you to reduce your attack surface.
