TL;DR: Healthcare security failures are being amplified by cloud, device, and application sprawl, with OCR reporting a 239% increase in hacking-related data breaches in 2023 and average breach costs reaching $10.93 million, according to Probely’s analysis. The governance problem is no longer whether controls exist, but whether they are embedded early enough to protect patient data across the full delivery stack.
Editorial analysis by NHI Mgmt Group, based on content published by Probely: “Protecting the Heart of Healthcare: Cybersecurity Strategies and Solutions”.
By the numbers:
- The Office of Civil Rights reported a 239% increase in hacking-related data breaches in healthcare in 2023.
- The average cost of a healthcare data breach is $10.93 million.
Key questions
Q: How should healthcare teams implement shift-left security across cloud, API, and application teams?
A: Start by placing security checks where change happens: source control, CI/CD, integration testing, and release approval.
Q: Why do healthcare APIs create risk even when core systems seem secure?
A: APIs often become the path by which authenticated systems exchange patient data, so a weakness in authorisation or exposure can bypass stronger controls elsewhere.
Q: What do security teams get wrong about mobile healthcare app protection?
A: They often stop at static testing or release-time review and underweight what happens after deployment.
Practitioner guidance
- Embed security tests in the SDLC Add static analysis, dynamic testing, and API checks to pull requests, build pipelines, and release gates so defects are caught before deployment.
- Map patient-data flows across cloud and APIs Document where patient data moves between cloud services, applications, and connected devices, then test the authorisation and logging points on those paths.
- Tighten API authorisation review Review whether each healthcare API enforces least-privilege access to records, functions, and integrations, especially where external systems exchange clinical data.
Bottom line: Healthcare security is being stretched by connected cloud, device, application, and API environments that no longer fit a late-stage testing model.

Healthcare now has an API governance problem, not just a testing problem: when care systems exchange data through loosely governed interfaces, the control failure is often authorisation drift rather than code quality alone. API testing only works when it is tied to access decisions, data flow mapping, and release gates. Practitioners should treat API security as part of healthcare identity and data governance, not a downstream developer task.
A few things that frame the scale:
- AI-related credential leaks surged 81.5% year-over-year in 2025, with the surrounding AI infrastructure leaking 5x faster than core LLM providers, according to the State of Secrets Sprawl 2026.
- 55% of healthcare data breaches now originate from a third-party vendor, according to Ponemon Institute’s 2023 Third-Party Risk in Healthcare report.
A question worth separating out:
Q: How can organisations tell whether shift-left security is actually reducing healthcare risk?
A: Look for fewer late-stage findings, faster remediation of interface and configuration issues, and clearer ownership of controls across development and operations. If vulnerabilities keep surfacing only after release, the programme has moved testing earlier in name but not in practice.
