For 2026, the updated HIPAA Security Rule will now explicitly mandate annual penetration testing for all covered entities and business associates. Vulnerability scans are now required to be executed semiannually. Penetration tests - annually. No exceptions, no flexibility, no more documentation on why the management chose not to.
This is long overdue. But as someone who has executed and led penetration testing engagements across critical infrastructure and regulated environments, I must state that healthcare penetration testing is not the same as testing a corporate network. Here are some quirks and risks that we encounter when working with such a sector:
Healthcare environments cannot be tested in the same way as normal infrastructure.
Healthcare systems keep people alive. An aggressive scan against a network segment running infusion pumps, patient monitors, or imaging systems can cause real, physical harm. As a result, the testing windows are usually narrow, rollback options are limited, and the tolerance for disruption is zero. Any penetration testing firm that does not build patient safety into its methodology from the start has no business operating in this space.
Scoping is where the engagements can go wrong.
Healthcare IT environments are usually messy. Legacy medical devices running unsupported operating systems may be located on the same network as modern cloud-hosted EHR platforms. IoT devices with no patching capability are often found as well. Many of these systems were never designed to be tested, and their manufacturers can void warranties or refuse further support. Defining what is in scope, and most importantly, what requires a careful, controlled approach, takes real expertise and close coordination with clinical engineering and security teams.
ePHI handling during testing is an important compliance risk.
Penetration testers who gain access to systems containing electronic protected health information need to be treated as any other party with access to that data. This means having proper agreements, data handling controls, and clear rules of engagement around what happens if live patient data is encountered. All these items are regulatory obligations.
The biggest risk is checkbox pen testing.
Low-cost, automated-scan-in-a-report engagements marketed as "HIPAA Penetration Testing" will flood the market to cover the new mandate as soon as it is set. These will only satisfy the basic validations. A vulnerability scan repackaged as a penetration test will not find the business logic flaws in a patient portal, test lateral movement from a compromised workstation to an ePHI database, or tell whether the network segmentation is done right.
To conclude, healthcare organizations need to approach this mandate as an opportunity, not a burden. If done right, penetration testing can reveal the gaps that lead to breaches, the kind that cost healthcare an average of over $10 million per incident.
At Parabellyx, our practice is built around the principle that penetration testing should deliver real security outcomes, not just compliance artifacts. We also proved its effectiveness by testing it in real-life healthcare environments and applications. If your organization is navigating the new HIPAA requirements and needs proper testing that accounts for the complexities of healthcare environments, we would love to chat.
