TL;DR: Annual penetration testing leaves healthcare environments exposed for most of the year while ransomware actors move in days, not months, according to Sprocket Security's analysis. Continuous testing shifts the focus from snapshot compliance to live exposure reduction, which is the more relevant control model for patient-care systems under pressure.
NHIMG editorial — based on content published by Sprocket Security: Continuous penetration testing narrows ransomware exposure in healthcare
By the numbers:
- In 2024, a cyberattack on Ascension Health forced staff across multiple states to disconnect clinical systems and hand-write medication orders for weeks.
Questions worth separating out
Q: How should healthcare security teams test ransomware exposure more effectively than once a year?
A: They should combine continuous attack surface monitoring with credentialed retesting after meaningful change.
Q: Why do ransomware groups target healthcare so aggressively?
A: Healthcare offers both operational urgency and high-value data.
Q: What breaks when vulnerability testing is tied to a yearly calendar?
A: The security picture goes stale before the next test begins.
Practitioner guidance
- Replace annual assurance with continuous exposure validation Track external services, DNS changes, vendor pathways, and new internet-facing assets continuously, then retest material changes before the next business cycle closes.
- Prioritise exploitability over report length Triage findings by whether an attacker can realistically chain them into lateral movement or privilege escalation, not by how many issues appear in a quarterly summary.
- Map healthcare third-party access as an identity control surface Inventory EHR vendors, support accounts, and remote access paths as governed identities with explicit ownership, scope, and offboarding triggers.
What's in the full article
Sprocket Security's full analysis covers the operational detail this post intentionally leaves for the source:
- How its continuous penetration testing workflow evaluates newly discovered services before the next annual assessment window.
- How human-reviewed retesting is used to decide whether a change is actually exploitable in a healthcare environment.
- How the platform produces attestation reports for auditors, boards, and cyber insurance evidence needs.
- How remediation and immediate verification are linked so teams can confirm exposure closure after fixes.

Annual testing creates a governance illusion in healthcare: it produces evidence of diligence without guaranteeing current exposure control. Healthcare environments change too quickly for a once-a-year model to provide durable assurance, especially where vendor access, cloud services, and clinical technology keep expanding. The practical conclusion is that security governance must track live attack surface change, not just annual sign-off.
A question worth separating out:
A: NIST CSF, NIST SP 800-53, and Zero Trust all fit because they emphasise ongoing control validation, access restriction, and resilience. For healthcare teams, the practical question is whether testing output is feeding remediation, verification, and accountability fast enough to reduce patient-care disruption.
