Ransomware in Healthcare: How to Vet the Security of Healthcare Software Vendors
This article is general information and not legal advice.
Healthcare organizations rely on software vendors for electronic health records, scheduling, billing, remote monitoring, payroll, secure messaging, analytics and dozens of other daily functions. Each vendor relationship can improve care delivery—but it can also introduce cybersecurity, privacy and compliance risk if the vendor has weak controls, excessive access or unclear responsibilities.
This article explains how healthcare administrators, compliance officers and IT teams can vet healthcare software vendors before signing a contract, during implementation and throughout the relationship, with practical checklists focused on ransomware in healthcare, EHR access security and healthcare phishing.
Why Vendor Security Vetting Matters in Healthcare
Healthcare software vendors often store, transmit or access protected health information, commonly called PHI. Under the HIPAA Rules, PHI includes individually identifiable health information held or transmitted by a covered entity or business associate in any form or medium.
A vendor may create risk even if it does not host your core electronic health record system. For example, a vendor may:
- Integrate with your EHR using an application programming interface, or API
- Maintain administrator access to troubleshoot your system
- Send email or text messages to patients
- Process billing, payroll or clinical documentation
- Store scanned documents, intake forms or authorizations
- Provide cloud backup, device management or remote support
- Use subcontractors that also handle PHI
From a compliance perspective, vendor security vetting helps support obligations under the HIPAA Security Rule, including administrative, physical and technical safeguards. Relevant HIPAA Security Rule provisions include, among others, 45 CFR 164.308, 45 CFR 164.310 and 45 CFR 164.312. Organizations should also consider the HIPAA Privacy Rule, HIPAA Breach Notification Rule and any applicable state privacy, breach notification, licensing, Medicaid, Medicare Advantage, payer or contractual requirements.
From an operational perspective, vendor vetting helps answer a simple question: If this vendor is compromised, misconfigured or unavailable, what happens to patient care, billing, documentation and regulatory compliance?The Vendor Risk Problem: Not All Software Risk Is Equal
A low-risk vendor that provides a public-facing marketing tool is not the same as a vendor that hosts PHI, integrates with your EHR and has remote administrative access. Vendor security vetting should be risk-based, not one-size-fits-all.
Common High-Risk Healthcare Software Vendors
Higher-risk vendors often include:
- EHR and electronic medical record platforms
- Revenue cycle management and billing systems
- Clinical documentation and quality reporting tools
- Patient portals and patient engagement platforms
- Telehealth platforms
- Remote patient monitoring platforms
- E-prescribing tools
- Laboratory, imaging or pharmacy interfaces
- Cloud hosting providers
- Managed service providers and IT support firms
- Cybersecurity monitoring vendors
- Backup and disaster recovery providers
- Staff scheduling, payroll or human resources systems containing sensitive workforce data
- Secure messaging or communication platforms
- Hospice, home health or clinic-specific workflow applications
These vendors may directly affect care coordination, medication management, orders, documentation, claims submission and survey readiness.
Questions to Ask Before You Begin
Before requesting documents from a vendor, define what the software will do in your environment:
- Will the vendor create, receive, maintain or transmit PHI?
- Will the vendor have access to your EHR?
- Will the vendor access your network remotely?
- Will the vendor use subcontractors?
- Will the system be cloud-hosted, locally installed or both?
- Will staff use single sign-on or separate usernames and passwords?
- Will patients access the system?
- Will the vendor send email or text messages on your behalf?
- What workflows stop if the vendor is unavailable?
- How quickly would you need restoration after an outage?
The answers help determine how deeply to vet the vendor.
Step 1: Classify the Vendor by Risk
Create a vendor risk tiering process. It does not need to be complicated, but it should be consistent and documented.
Example Vendor Risk Tiers
| Risk Tier | Description | Examples | Review Level | |---|---|---|---| | Tier 1: Critical / High Risk | Stores PHI, integrates with EHR, supports clinical operations or has privileged access | EHR, billing, telehealth, managed IT, backup provider | Full security review, legal review, business associate agreement, ongoing monitoring | | Tier 2: Moderate Risk | Handles limited PHI or sensitive business data but is not mission-critical | HR platform, limited patient engagement tool, quality dashboard | Security questionnaire, contract review, limited documentation review | | Tier 3: Low Risk | No PHI or sensitive access; minimal operational dependency | Public website design tool with no patient data | Basic review, confirmation of no PHI, contract terms |
Your organization may define tiers differently. The important point is to avoid treating every vendor the same while also avoiding informal “trust us” approvals for high-risk systems.
Vendor Intake Checklist
Use a standard intake form before approving a new healthcare software vendor:
- Vendor name and product name
- Business owner or department requesting the product
- Purpose of the software
- Type of data involved, including PHI, personally identifiable information and financial data
- Whether the vendor is expected to be a business associate
- Systems the vendor will connect to
- Authentication method
- User roles and permissions
- Remote access requirements
- Hosting model
- Subcontractors or third-party integrations
- Data retention and deletion expectations
- Backup and recovery expectations
- Implementation timeline
- Contract owner
- Security review status
- Compliance review status
- Approval decision and date
Step 2: Determine Whether a Business Associate Agreement Is Required
Under HIPAA, a business associate is generally a person or entity, other than a member of the covered entity’s workforce, that performs certain functions or activities involving PHI on behalf of a covered entity, or provides certain services involving PHI. Business associate determinations can be fact-specific.
If the vendor will create, receive, maintain or transmit PHI on your behalf, you should evaluate whether a Business Associate Agreement, commonly called a BAA, is required. BAAs are addressed under the HIPAA Rules, including 45 CFR 164.308 and 45 CFR 164.502. Organizations should consult qualified counsel when legal interpretation is needed.
Practical BAA Review Points
A BAA should not be treated as a paperwork formality. Review whether it addresses:
- Permitted and required uses and disclosures of PHI
- Safeguards to protect PHI
- Reporting of security incidents and breaches
- Subcontractor obligations
- Access, amendment and accounting obligations where applicable
- Return or destruction of PHI at termination, where feasible
- Termination rights for material breach
- Responsibilities for breach notification support
- Cooperation with investigations, audits or regulatory inquiries
- Data location and subcontractor use, where relevant
Do not assume a vendor’s standard BAA is sufficient for your organization’s risk profile. High-risk vendor arrangements may require additional contract terms beyond the BAA.
Step 3: Evaluate Ransomware Readiness
Ransomware in healthcare is especially disruptive because downtime can interfere with documentation, scheduling, medication workflows, claims, patient communication and continuity of care. Vendor vetting should examine not only whether the vendor tries to prevent ransomware, but also whether it can recover.
Ransomware Vendor Security Questions
Ask high-risk vendors:
- Do you maintain an incident response plan?
- How are backups protected?
- How often do you test restoration?
- What is your recovery time objective and recovery point objective?
- Do you use multifactor authentication for administrative access?
- How do you secure remote access?
- How do you segment customer environments?
- Do you conduct vulnerability scanning and patch management?
- Do you conduct tabletop exercises?
- How and when will you notify customers of a security incident?
Red Flags for Ransomware Risk
Be cautious if a vendor:
- Cannot explain its backup and restoration process
- Does not require MFA for administrative access
- Shares generic security claims without evidence
- Refuses to discuss incident notification commitments
- Uses unsupported software or cannot describe patching practices
- Allows broad remote access without logging or approval
- Has no defined disaster recovery process
- Cannot identify where customer data is stored
- Cannot explain subcontractor security oversight
Step 4: Review EHR Access Security
EHR access security is one of the most important areas of vendor risk. A vendor may not host your EHR, but it may still connect to it, extract data from it or support users who access it.
Key EHR Access Security Controls
When a vendor connects to your EHR or receives EHR data, assess the following:
#### Role-Based Access
Role-based access means users receive permissions based on their job function. A vendor should not receive more access than necessary.
Ask:
- What roles will the vendor require?
- Does the vendor need read-only access or write access?
- Does the vendor need access to all patients or a limited population?
- Can access be restricted by location, department or program?
- Who approves access changes?
- How often are permissions reviewed?
#### Unique User Accounts
Avoid shared accounts whenever possible. Unique user accounts support accountability because activity can be tied to a specific person.
Ask:
- Will each vendor user have a unique account?
- Are shared administrator accounts prohibited or tightly controlled?
- Are service accounts documented and restricted?
- Are dormant accounts automatically disabled?
- How quickly is access removed when vendor staff leave?
#### Multifactor Authentication
MFA should be required for remote access, privileged access and access to systems containing PHI whenever feasible and appropriate. Requirements may also be influenced by cyber insurance, payer contracts, state expectations or specific security frameworks.
Ask:
- Is MFA required for vendor access?
- What MFA methods are supported?
- Is MFA required for administrative functions?
- Are exceptions documented and approved?
#### Audit Logging
Audit logs record user and system activity. They are essential for investigating suspicious access, inappropriate viewing or data changes.
Ask:
- What vendor activity is logged?
- Can your organization review logs related to your environment?
- How long are logs retained?
- Are logs monitored for suspicious activity?
- Can logs be exported during an investigation?
- Are failed login attempts tracked?
#### Interface and API Security
APIs and interfaces can create high-volume data pathways between systems.
Ask:
- What data elements are exchanged?
- Is data encrypted in transit?
- Are API keys or tokens protected and rotated?
- Are access scopes limited?
- Is testing performed before production activation?
- Are interface errors monitored?
- What happens if the interface fails?
Practical Example: Limiting EHR Integration Risk
If a home health agency uses a third-party analytics tool to track quality measures, the tool may not need full clinical record access. Instead of granting broad access, the agency could work with the vendor to provide a limited data feed containing only the required fields. Access should be documented, approved, monitored and reviewed periodically.
Step 5: Assess Healthcare Phishing Risk
Healthcare phishing remains a major concern because attackers often target users through email, text messages, fake login pages and fraudulent invoices. Vendor relationships can increase phishing risk when vendors send messages to staff or patients, use lookalike domains or request credentials through insecure workflows.
Vendor Phishing Risk Areas
Evaluate whether the vendor:
- Sends emails to your workforce
- Sends appointment reminders or portal invitations to patients
- Sends invoices or payment links
- Uses links that redirect to third-party platforms
- Uses a domain that resembles your organization’s domain
- Provides remote support by email invitation
- Asks users to enter credentials outside approved login pages
- Sends attachments containing PHI
- Uses secure messaging or encrypted email where appropriate
Questions to Ask Vendors About Email Security
For vendors sending email on your behalf, ask:
- What domain will messages come from?
- Can email authentication be configured using SPF, DKIM and DMARC?
- Will messages clearly identify the vendor and purpose?
- Are links branded and consistent?
- Can staff and patient communications be reviewed before launch?
- Does the vendor support secure messaging for PHI?
- How does the vendor prevent fraudulent payment redirection?
- How are compromised vendor email accounts handled?
- Will the vendor notify you of phishing campaigns impersonating its platform?
SPF, DKIM and DMARC are email authentication controls that help reduce spoofing and improve trust in legitimate messages. They do not eliminate phishing, but they are useful layers in an email security program.
Staff Training Example
Before launching a new patient communication platform, send staff a short advisory:
> Beginning November 4, appointment reminder messages will be sent through ExampleCare Messaging. Staff may receive administrative emails from notifications@examplecare.example. Do not enter your EHR password into any page linked from these emails. Report suspicious messages through the help desk or phishing report button.
This simple communication reduces confusion and gives staff a clear reporting path.
Step 6: Request Security Documentation
For moderate- and high-risk vendors, ask for documentation that supports their security claims. The specific documents will vary based on vendor type and sensitivity.
Useful Documents to Request
Depending on the relationship, request:
- Completed security questionnaire
- HIPAA compliance overview or security program summary
- Independent audit report, such as a SOC 2 report, if available and applicable
- Penetration testing summary or attestation, if available
- Vulnerability management policy summary
- Incident response policy summary
- Disaster recovery and business continuity summary
- Encryption description for data at rest and in transit
- Access control policy summary
- Data retention and deletion policy
- Subcontractor list or subprocessors list
- Secure software development lifecycle summary
- Privacy policy, where patient-facing tools are involved
- Cyber liability insurance certificate, if required by your organization
- Business Associate Agreement, if applicable
A vendor may not be able to provide every document, especially smaller vendors. The goal is not to collect paperwork for its own sake. The goal is to determine whether the vendor’s controls are appropriate for the risk.
How to Review a SOC 2 Report Carefully
A SOC 2 report can be helpful, but it does not automatically prove HIPAA compliance. If a vendor provides one, review:
- Report period
- Scope of systems covered
- Trust Services Criteria included
- Complementary user entity controls, which are controls your organization is expected to operate
- Exceptions or findings
- Subservice organizations
- Whether the product you are buying is included in scope
If you do not have internal expertise to review audit reports, involve IT security, compliance leadership or an external advisor.
Step 7: Review Contract Terms Beyond Price and Features
Security obligations should be written into contracts. A vendor’s sales presentation is not enough.
Contract Security Topics to Address
Work with counsel and appropriate stakeholders to review:
- Business Associate Agreement requirements, if applicable
- Security safeguards
- Encryption expectations
- Access controls and MFA
- Incident reporting timelines and cooperation
- Breach notification support
- Audit rights or assurance documentation
- Data ownership
- Data retention and deletion
- Return of data at termination
- Subcontractor approval or notification
- Offshore access or storage, if relevant
- Service availability commitments
- Disaster recovery commitments
- Support response times
- Change management
- Indemnification and limitation of liability
- Cyber insurance requirements
- Regulatory cooperation
- Termination rights for security failures
Requirements vary by state, payer, contract type and organizational risk tolerance. Legal counsel should review terms where interpretation or negotiation is needed.
Avoid Vague Security Language
Weak contract language:
> Vendor will use reasonable security measures.
Stronger contract concept:
> Vendor will maintain administrative, physical and technical safeguards designed to protect PHI and will require multifactor authentication for remote administrative access to systems containing customer PHI, except where mutually documented and approved.
Contract language should be tailored to the vendor relationship and reviewed by qualified counsel.
Step 8: Validate Implementation Before Go-Live
Vendor vetting does not end when the contract is signed. Many security failures occur during implementation because settings are rushed, defaults are accepted or access is over-permissioned.
Pre-Go-Live Security Checklist
Before launching the software:
- Confirm BAA execution, if applicable
- Confirm approved data flows
- Confirm user roles and permissions
- Confirm MFA configuration
- Confirm logging is enabled
- Confirm encryption settings
- Confirm interface testing
- Confirm backup and recovery expectations
- Confirm incident reporting contacts
- Confirm support escalation path
- Confirm secure email or messaging configuration
- Confirm patient-facing notices or instructions, if applicable
- Confirm staff training materials
- Confirm downtime procedures
- Confirm termination and data export process
- Document approval to go live
EHR Integration Go-Live Questions
For EHR-connected vendors:
- Has a test environment been used before production?
- Have interface mappings been validated?
- Has access been limited to necessary data?
- Are failed transactions monitored?
- Is there a rollback plan?
- Who receives alerts if data stops flowing?
- Who approves changes to the interface?
Step 9: Monitor Vendors After Approval
Healthcare vendor risk changes over time. Vendors add features, change hosting providers, use new subcontractors, update integrations or experience security incidents. Your vendor management process should include ongoing oversight.
Ongoing Vendor Monitoring Activities
For high-risk vendors, consider:
- Annual security review
- Updated security questionnaire
- Updated SOC 2 or audit report review, if available
- Review of subcontractor changes
- Review of access lists
- Confirmation of MFA
- Review of incident history affecting your environment
- Disaster recovery test confirmation
- Contract and BAA review before renewal
- User access recertification
- Review of data retention and deletion practices
- Review of support tickets for recurring security issues
Access Recertification Checklist
At least periodically, confirm:
- Current vendor users
- Current internal users with access to the vendor system
- Privileged accounts
- Service accounts
- Inactive accounts
- Role appropriateness
- MFA status
- Terminated workforce access removal
- Unusual access patterns, where logs allow review
Frequency should be based on risk and applicable requirements. Some organizations perform quarterly reviews for critical vendors and annual reviews for moderate-risk vendors.
Step 10: Plan for Vendor Downtime and Exit
Even strong vendors can experience outages, cyber incidents, contract disputes or business changes. Healthcare organizations need plans for continuity and exit.
Downtime Planning Questions
Ask:
- What workflows depend on this vendor?
- What happens if the system is unavailable for four hours, one day or one week?
- Can clinicians access essential information during downtime?
- Are paper forms available?
- How will documentation be entered later?
- Who communicates with staff?
- Who communicates with patients, if needed?
- How are urgent orders, visits or medication-related workflows handled?
- How is billing delayed or resumed?
- How are compliance deadlines tracked?
Exit Planning Questions
Before signing, determine:
- How will your data be exported?
- What format will data be provided in?
- How long will export take?
- Are there extra fees?
- How will vendor copies be returned or destroyed?
- What happens to backups containing your data?
- How will access be disabled?
- How will subcontractors be addressed?
- What support is available during transition?
Exit planning is especially important for home health agencies, hospices, clinics and staffing firms that rely on software for daily documentation and billing.
Hypothetical Scenario: A Vendor Review Prevents Excessive EHR Access
The following is a hypothetical example, not a real client or real organization.
A mid-sized home health agency is evaluating a new scheduling and care coordination platform. The vendor says it can integrate with the agency’s EHR and asks for a full administrator account “temporarily” to speed up implementation. The operations team likes the product and wants to launch quickly because schedulers are struggling with manual processes.
The compliance officer initiates the agency’s vendor security review. During the review, the team learns that the platform only needs patient demographics, visit schedules, clinician assignments and limited order status information. It does not need full clinical notes, billing records or administrator-level access.
The agency takes the following actions:
- Classifies the vendor as high risk because it will receive PHI and integrate with the EHR
- Executes a BAA after legal review
- Requires unique vendor user accounts rather than a shared account
- Limits the vendor’s access to only the required interface and data elements
- Requires MFA for remote access
- Confirms logging of vendor activity
- Reviews the vendor’s incident response and backup summaries
- Documents downtime procedures if the scheduling platform is unavailable
- Sends staff a notice explaining expected vendor emails to reduce healthcare phishing risk
The result is a more controlled implementation. The agency still gains the operational benefit of the scheduling tool, but it avoids unnecessary EHR administrator access and creates a record of security due diligence.
Vendor Security Questionnaire: Practical Starter Set
A questionnaire should be proportionate to the risk. Below is a starter set for healthcare software vendors that may handle PHI.
Organization and Compliance
- Does your product create, receive, maintain or transmit PHI?
- Will you sign a Business Associate Agreement if required?
- Do you use subcontractors or subprocessors that may access PHI?

- How do you determine whether customer data was affected?
- What are your customer notification procedures?
- Who is the incident contact?
- Do you conduct incident response exercises?
Business Continuity and Disaster Recovery
- Do you maintain a business continuity plan?
- Do you maintain a disaster recovery plan?
- What are your RTO and RPO targets?
- How often are backups tested?
- How often are recovery procedures tested?
- Do you provide downtime updates to customers?
Email, Messaging and Phishing Controls
- Will you send emails or text messages to staff or patients?
- What domains will be used?
- Do you support SPF, DKIM and DMARC alignment?
- Do messages contain PHI?
- Are links protected or monitored?
- How do you handle compromised accounts?
- How do you help customers identify legitimate communications?
Special Considerations for Home Health, Hospice, Staffing and Clinics
Different healthcare settings face different vendor security challenges.
Home Health and Hospice
Home health and hospice providers often depend on mobile documentation, scheduling, route planning, billing, quality reporting and remote access. Field staff may use tablets or phones outside controlled office environments.
Key considerations:
- Mobile device management
- Offline documentation security
- Lost or stolen device procedures
- Secure synchronization
- Role-based access for clinicians, aides and contractors
- Timely removal of access for separated staff
- Downtime procedures for visits and care coordination
- Integration with EHR and billing systems
Medicare Conditions of Participation for home health are found at 42 CFR Part 484. Hospice Conditions of Participation are found at 42 CFR Part 418. Software vendor controls can affect documentation, care coordination and operational readiness, though the specific implications depend on the workflow and facts.
Healthcare Staffing Firms
Healthcare staffing firms may manage credentialing records, background information, health records, assignment details and client facility requirements. Some data may be PHI, while other data may be sensitive employment or occupational health information.
Key considerations:
- Access control for recruiters, credentialing staff and clients
- Secure document upload
- Segregation of client data
- Secure transmission of credentialing documents
- Phishing-resistant payroll and direct deposit change processes
- Contractor offboarding
- Retention requirements, which may vary by state, contract and payer
Clinics
Clinics often rely on EHRs, patient portals, e-prescribing, lab interfaces, billing platforms and reminder systems. Smaller clinics may not have dedicated security staff, making vendor due diligence especially important.
Key considerations:
- EHR access security
- Patient portal configuration
- Secure messaging
- Lab and imaging interfaces
- Payment processing workflows
- Email domain protection
- Backup and recovery
- Managed IT vendor oversight
Common Mistakes to Avoid
Mistake 1: Letting Departments Buy Software Without Security Review
Shadow IT occurs when departments adopt technology without IT or compliance approval. This can lead to unapproved PHI storage, weak passwords, missing BAAs and unclear data ownership.
Action: Require a vendor intake process before purchase or implementation.Mistake 2: Assuming “HIPAA Compliant” Is Enough
Vendors may use the phrase “HIPAA compliant” broadly. Ask what controls are in place, what services are covered and what your organization must do to configure and use the product securely.
Action: Request documentation and clarify shared responsibilities.Mistake 3: Ignoring Subcontractors
A vendor may rely on cloud providers, messaging platforms, analytics tools or support contractors.
Action: Ask for a subprocessors list and notification process for material changes.Mistake 4: Overlooking User Access Reviews
Even secure systems become risky when users accumulate unnecessary access.
Action: Review vendor and internal user access periodically.Mistake 5: Failing to Plan for Downtime
If a vendor outage stops scheduling, documentation or billing, patient care and operations can suffer.
Action: Create downtime procedures and test them.Mistake 6: Not Coordinating Phishing Awareness
When a new vendor starts sending messages, staff may not know what is legitimate.
Action: Communicate expected vendor domains, message types and reporting steps.A Practical Vendor Vetting Workflow
Use this workflow to standardize reviews:
- Request submitted
- Initial risk classification
- BAA determination
- Security questionnaire sent
- Documentation collected
- Contract review completed
- Implementation controls validated
- Staff communication issued
- Go-live approved
- Ongoing monitoring scheduled
Conclusion and Next Steps
Vetting healthcare software vendors is not just an IT task. It is a healthcare security and compliance function that affects patient care, privacy, billing continuity, workforce operations and regulatory readiness. Strong vendor due diligence helps reduce risk from ransomware in healthcare, strengthens EHR access security and lowers healthcare phishing exposure.
Start by building a simple, repeatable vendor intake and risk classification process. Then prioritize your highest-risk vendors: EHR-connected platforms, billing systems, patient communication tools, managed IT providers, backup vendors and any vendor with PHI or remote administrative access. Review contracts, validate implementation settings and monitor vendors throughout the relationship.
