The Critical Importance of Due Diligence in Healthcare M&A: Safeguarding IT Assets and Mitigating Cybersecurity Risks
As healthcare systems increasingly pursue mergers and acquisitions (M&A) to streamline operations, enhance patient care, and bolster financial performance, the risks tied to integrating IT environments are often overlooked or underestimated. While a merger can promise substantial cost savings, improved infrastructure, and broader access to technology, it can also bring to light a host of cybersecurity vulnerabilities that threaten the entire deal.
For any hospital or healthcare organization, due diligence in the IT and cybersecurity space is no longer an option—it’s a necessity. The failure to understand the full scope of a target’s IT infrastructure, security posture, and liabilities can lead to unexpected breaches, regulatory violations, and reputational damage, ultimately diminishing the return on investment (ROI) of the merger.
Hidden IT Liabilities: The Core Risk in Healthcare M&A
When hospitals merge, they are not just blending medical expertise and administrative systems; they are fusing complex IT infrastructures, each with its unique legacy systems, cloud environments, software, and security controls. Without a comprehensive review, these IT environments may harbor significant risks:
Legacy Systems Vulnerabilities: Many healthcare organizations still operate on outdated software or legacy systems, which are rife with unpatched vulnerabilities. When combined with another organization’s infrastructure, these gaps can be exploited by malicious actors, leading to breaches that expose sensitive patient data or disrupt critical hospital operations.
Unknown Software and Shadow IT: Merging entities may have multiple software programs and systems running under the radar, often referred to as Shadow IT. These applications often escape centralized monitoring, leaving them vulnerable to attacks. Not knowing what’s running in your system significantly raises the risk of backdoor entry points for attackers.
Unsecured Medical Devices: IoT and connected medical devices like pacemakers, MRI machines, and patient monitoring systems are increasingly targeted by cybercriminals. These devices often run on outdated firmware or are not adequately secured, creating easy attack vectors for those looking to infiltrate hospital networks.
Divergent Security Postures: Different hospitals will have varying levels of cybersecurity maturity. One may have a robust system with full encryption and strict access controls, while the other may still rely on outdated methods, leaving sensitive data like electronic health records (EHRs) vulnerable. Merging these two systems without full awareness of their current security posture can lead to lapses that become avenues for attacks.
Third-Party and Supply Chain Risks: Healthcare organizations rely heavily on third-party vendors for everything from medical devices to IT support. Each of these partners introduces additional cybersecurity risks. If one merging entity has not thoroughly vetted its third-party vendors, these vulnerabilities will be inherited by the new, merged organization.
Regulatory Non-Compliance: Healthcare is one of the most heavily regulated industries, with frameworks such as HIPAA, HITECH, and GDPR imposing strict requirements on how patient data is managed and protected. Failing to identify and address compliance gaps during the M&A process can lead to severe legal consequences, including hefty fines and loss of public trust.
The Impact of Cybersecurity Lapses on ROI
Security breaches in the wake of an M&A deal can have devastating effects on ROI, often offsetting any expected financial gains from the merger. Consider the potential outcomes:
Data Breaches: A breach can expose sensitive patient records, triggering lawsuits, fines, and severe reputational damage. The cost of a healthcare data breach averages around $10 million—funds that could have been reinvested in expanding services or improving patient care.
Operational Disruption: Cyberattacks targeting IT infrastructure can halt critical operations, delaying patient care and resulting in a loss of revenue. In severe cases, hospitals may be forced to shut down operations until the threat is resolved, further eating into anticipated savings or profits.
Increased Post-Merger Integration Costs: Unforeseen security lapses often require extensive remediation efforts, which inflate post-merger integration costs. These additional expenses can erode any financial benefits projected during the deal.
Regulatory Penalties: Compliance violations discovered after the merger can lead to regulatory penalties that wipe out any financial gains. Additionally, addressing these violations often requires diverting resources from core healthcare activities to costly compliance initiatives.
Merger and Acquisition Risk Management of Cyber Threats
Here are three case studies highlighting mergers and acquisitions in the healthcare sector that encountered significant cybersecurity challenges due to lapses in due diligence:

- Insight: IT due diligence must go beyond asset discovery. Organizations need in-depth vulnerability scanning, regulatory compliance checks, and vendor audits. A key takeaway here is that M&A teams need a dedicated cybersecurity audit that parallels financial and operational due diligence.
2. Legacy Systems as Critical Vulnerabilities
- Prioritize Legacy System Integration: Legacy systems are often the weakest link in a merged IT environment. Both the acquiring and target companies need to assess the viability of continuing to use older systems or plan for a rapid transition to secure, up-to-date solutions.
- Case Studies: The CHS and IBM-Merge examples reinforce how poorly integrated or unmonitored legacy systems have led to massive post-merger data breaches and compliance failures.
- Insight: Legacy systems aren’t just an IT headache; they are a ticking time bomb. To manage this risk, companies must establish a plan for legacy system integration or retirement prior to the merger. This involves conducting a risk assessment of legacy systems and building an action plan for remediation or modernization as part of the post-merger integration process.
3. Third-Party Risk Management
- Third-Party Risk Management: As seen in the IBM-Merge case, third-party vendors can introduce significant vulnerabilities. Due diligence must extend beyond the immediate IT infrastructure to include a full review of vendor contracts and their security posture.
- Case Studies: The IBM-Merge case underscores how third-party vendor risks can delay integration and introduce regulatory headaches.
- Insight: Third-party risk is often underestimated. A clear strategy must include extending cybersecurity due diligence to all external vendors associated with both companies in the M&A. This involves vendor audits, reviewing SLAs for security standards, and ensuring robust monitoring is in place post-merger.
4. Regulatory Compliance and Security Posture Alignment
- Regulatory Compliance and Security Posture Alignment: As demonstrated by the IBM-Merge and CHS cases, failure to align regulatory compliance and security protocols can lead to costly penalties and legal challenges. Merging organizations must ensure that both entities meet relevant healthcare regulations like HIPAA and GDPR. This requires a thorough review of each entity’s compliance posture, security policies, and data handling practices to prevent post-merger violations. Proper alignment not only protects sensitive patient data but also avoids the legal and financial fallout of non-compliance.
- Case Studies: The IBM-Merge and CHS breaches show how non-compliance with regulations resulted in increased costs, delays, and legal liabilities.
- Combined Insight: Ensuring alignment with regulatory standards isn’t just about compliance; it’s about protecting sensitive patient data and avoiding severe penalties. Organizations must ensure that security postures and compliance protocols align during the integration phase, conducting security audits that specifically address HIPAA, GDPR, or other relevant healthcare regulations.
