Adversary-grade penetration testing for healthcare
We attack your hospital or clinic the way a real intruder would, across networks, web and cloud apps, the EHR, and connected medical devices, then hand you a clear, prioritized plan to fix what we find. All without disrupting patient care or endangering devices on the clinical floor.
Healthcare penetration testing is an authorized simulated cyberattack on a hospital or clinic's systems, networks, applications, the EHR, and connected medical devices, performed to find exploitable weaknesses before a real attacker does. Dark Analytics tests the way a determined adversary would, but safely inside live clinical environments, and delivers a board-ready report plus a prioritized fix list and a retest to confirm the fixes held.
What a healthcare penetration test is, and why hospitals need one
A penetration test is an authorized, simulated attack on your environment. We don't run a scanner and email you the output. We chain real weaknesses together the way an actual intruder would, exploiting a misconfiguration, pivoting across the network, escalating privileges, and proving exactly how far an attacker could get and what they could reach: ePHI, the EHR, domain admin, the medical-device network.
Healthcare is a uniquely hard target to defend. Hospitals run flat networks, legacy operating systems that can't be patched, and thousands of connected devices that were never designed with security in mind. A vulnerability scan tells you a door is unlocked. A penetration test walks through it, tells you what's on the other side, and shows you which doors actually matter.
The stakes are not abstract. Per IBM's 2024 Cost of a Data Breach Report, healthcare has the highest average breach cost of any industry at roughly $9.77M, a position it has held for more than a decade. The goal of testing is simple: find and fix the paths an attacker would use before they cost you patients, dollars, and trust.
What we test
We scope every engagement to your environment and your risk. Most hospital and clinic tests cover several of the following, and we'll recommend a mix during scoping:
- External network, internet-facing infrastructure: VPNs, remote access, patient and provider portals, email security, and exposed services an attacker hits from the outside.
- Internal network, what a malicious insider, a compromised laptop, or an attacker who got past the perimeter can reach. This is where flat networks and weak segmentation usually surface.
- Web and cloud applications, patient portals, scheduling and billing apps, custom clinical tools, APIs, and Microsoft 365 / Azure / AWS configurations, tested against the OWASP Top 10 and beyond.
- Clinical systems and the EHR, authentication, access controls, role-based permissions, and HL7 / DICOM interfaces, validating whether ePHI is properly protected and whether least-privilege actually holds.
- IoMT and medical devices, infusion pumps, imaging (PACS and modalities), patient monitors, and other connected devices: assessing exposure, segmentation, default credentials, and known critical vulnerabilities, always with patient safety first.
- Wireless, corporate, guest, clinical, and biomedical SSIDs; rogue access points; and whether a parking-lot attacker can reach the networks that matter.
- Social engineering and phishing, targeted phishing, pretext calls, and (where in scope) physical access, because the fastest way into most healthcare networks is still a person, not a port.
Our methodology
We follow a structured, repeatable process aligned to recognized standards, the Penetration Testing Execution Standard (PTES), the OWASP Testing Guide for web and API work, MITRE ATT&CK for adversary techniques, and NIST SP 800-115 as the technical baseline for security testing. We only name standards that genuinely apply to your scope.
Every test moves through the same phases: reconnaissance and mapping, vulnerability identification, controlled exploitation, post-exploitation (privilege escalation, lateral movement, and proving impact such as access to ePHI or the EHR), and clear reporting with reproducible evidence.
We don't stop at the first vulnerability. The value is in the chain, showing how a low-severity foothold becomes domain compromise, because that's the story your board and your auditors need to understand, and the story a real attacker would write.
How we test safely in live clinical environments
Testing a hospital is not testing a tech startup. A crashed server can mean a delayed diagnosis, and an aggressive scan against an infusion pump or patient monitor is a patient-safety event, not just an IT problem. We treat it that way.
Before anything runs, we agree on rules of engagement in writing: scope, timing, escalation contacts, and explicit go / no-go criteria. We coordinate windows with your IT and clinical engineering teams, and high-risk targets, especially live medical devices, are handled with passive and read-only techniques, lab or test-bench methods, or careful, supervised approaches rather than blunt-force exploitation.
- Defined rules of engagement, named points of contact, and a real-time stop procedure that pauses testing the moment patient care could be affected.
- Medical devices and IoMT are assessed with safety-first techniques, passive observation, configuration and segmentation review, and controlled testing, never reckless exploitation of devices attached to patients.
- Active testing scheduled around clinical operations, with continuous communication so your team always knows what we're doing and when.
- An emergency rollback and de-confliction plan so that if something looks like an outage, we can immediately confirm whether it's us and back off.
What you get, deliverables
A penetration test is only as useful as what you can do with it. Our reporting is built to drive action at every level of the organization, from the board to the engineer who applies the fix.
- Executive / board-ready summary, plain-language risk narrative, business impact, and overall posture, written so a non-technical leader, auditor, or insurer can understand it.
- Technical findings with severity, each issue rated (typically CVSS-aligned), with evidence, reproduction steps, affected systems, and the realistic attack path we proved.
- Prioritized remediation roadmap, what to fix first, sequenced by real-world risk and exploitability, not just raw scanner scores, with concrete guidance your team can act on.
- A debrief with your team to walk through findings and answer questions, and a retest after you remediate, so you can verify the fixes worked and demonstrate closure to leadership, auditors, and cyber-insurers.
How it works
- 01
Scope and rules of engagement
We define targets, objectives, timing, and explicit go / no-go criteria with your IT and clinical engineering teams, and put authorization and escalation contacts in writing before any testing begins.
- 02
Reconnaissance and mapping
We map your attack surface the way an adversary would, external footprint, internal network, applications, wireless, devices, and people, to find the paths most likely to matter.
- 03
Exploitation
We safely exploit the weaknesses we find to confirm they're real and not theoretical, using safety-first techniques on clinical systems and medical devices and coordinating closely around live patient care.
- 04
Post-exploitation
We escalate privileges and move laterally to prove true business impact, what an attacker could actually reach, including ePHI, the EHR, and the medical-device network, then chain findings into the full attack story.
- 05
Reporting, debrief, and retest
You receive a board-ready report, severity-rated technical findings, and a prioritized remediation roadmap, plus a live debrief and a retest to verify your fixes held.
Frameworks & standards we align to
Every finding maps back to the standards your auditors, board, and cyber-insurer already speak.
Frequently asked questions
Will a penetration test disrupt patient care?
Not when it's done right. Disruption is the single biggest concern in healthcare testing, and we engineer the engagement around avoiding it. We agree on rules of engagement, scheduling, and a real-time stop procedure up front, coordinate active testing with your IT and clinical teams, and use safety-first, passive, or controlled techniques against anything connected to patient care. If testing ever looks like it could affect operations, we pause immediately, confirm whether it's us, and adjust. The objective is to find what an attacker would find, without becoming the incident ourselves.
Do you test medical devices and IoMT?
Yes, and we do it with patient safety as the hard constraint. Connected medical devices like infusion pumps, imaging systems (PACS and modalities), and patient monitors are a major and often-overlooked attack surface; in its 2022 State of Healthcare IoT Device Security report, Cynerio found that roughly 53% of connected medical devices carry a known critical vulnerability. We assess device exposure, network segmentation, default and shared credentials, and known vulnerabilities using passive observation, configuration and segmentation review, and lab or controlled testing rather than reckless exploitation of devices attached to patients.
How often should a hospital or clinic get a penetration test?
At minimum annually, and again after any significant change, a new EHR or major application, a merger or acquisition, a network redesign, a cloud migration, or the rollout of a new fleet of connected devices. Annual testing is widely treated as a baseline expectation by auditors, cyber-insurers, and security frameworks, but environments change constantly, and each major change can open paths that last year's test never saw. Many healthcare organizations pair an annual penetration test with more frequent vulnerability scanning between engagements.
What's the difference between black box, grey box, and white box testing?
It comes down to how much we know going in. Black box means we start with little or no inside information, simulating an external attacker discovering everything from scratch, realistic, but slower and with less guaranteed coverage. White box means we get full information (architecture, credentials, sometimes source) for the deepest, most thorough assessment of a system. Grey box sits in the middle, typically with some access or low-privilege credentials, and is the most common and cost-effective choice for healthcare because it efficiently models the very realistic scenario of an attacker who already has a foothold. We'll recommend the right approach for each target during scoping.
Does penetration testing satisfy HIPAA, payer, or cyber-insurance requirements?
It directly supports them. The HIPAA Security Rule requires a risk analysis and ongoing evaluation of your safeguards (NIST SP 800-66 Rev. 2, developed with HHS OCR, and NIST SP 800-30 provide the referenced risk-assessment guidance), and penetration testing is a recognized way to evaluate whether those technical safeguards actually hold up against attack. HIPAA does not name 'penetration test' as a specific checkbox, but OCR, payers, and cyber-insurance carriers increasingly expect regular testing as evidence of due diligence, and many insurance applications and renewals now ask for it directly. Our reporting and retest are built to give auditors, partners, and insurers the documentation they want to see.
How is a penetration test different from a vulnerability scan?
A vulnerability scan is automated and broad, it lists potential weaknesses but doesn't confirm whether they're truly exploitable or what an attacker could actually do with them, and it produces noise and false positives. A penetration test is human-driven: we validate findings by safely exploiting them, chain weaknesses together, and prove real business impact, such as reaching ePHI or compromising the domain. Scanning tells you what might be wrong; a penetration test tells you what an attacker would actually do and what to fix first. Both have a place, scan continuously, test deeply.
