The Importance of Cyber Risk Due Diligence in M&A for Private Equity Firms

Mergers and acquisitions (M&A) are complex, high-stakes ventures for private equity (PE) firms. While financial performance, market fit, and strategic alignment are crucial factors, the resilience of a target company's digital infrastructure can significantly influence deal outcomes. Cyber risk has emerged as a potential deal-maker or deal-breaker, making thorough cyber due diligence essential for successful M&A.

Why Cyber Risk Matters in M&A

For private equity firms, a successful acquisition requires more than a favorable financial outlook; it depends on the target company’s resilience to cyber risks. Without thorough cyber assessments, PE firms risk taking on unforeseen liabilities that can diminish deal value, increase integration costs, and shake investor confidence.

The financial implications are significant—data breaches cost an average of $4.45 million in 2024, making it essential to identify vulnerabilities during due diligence. Overlooking these risks can lead to costly post-acquisition remediation. Additionally, regulatory compliance is crucial. In industries subject to GDPR, CCPA, or HIPAA, inadequate cybersecurity can lead to steep fines that erode the acquisition’s value proposition.

Beyond financial and regulatory concerns, a breach after acquisition can severely harm both the target’s reputation and the PE firm’s credibility. Investors expect that acquired companies have solid cybersecurity measures, and a breach can erode trust and deter future investment. For these reasons, cybersecurity should be at the forefront of M&A strategy, safeguarding the investment from potential risks.

Key Areas of Cyber Risk Due Diligence

In M&A, managing cyber risk is essential not just for safeguarding assets but for ensuring the deal’s overall success. For private equity firms, understanding and addressing these risks can streamline integration, protect reputation, and reduce financial exposure. Here’s how a targeted approach to cyber risk can make a meaningful difference:

• Identify and Prioritize Key Risks: It’s not enough to know where all potential threats are; the priority should be on identifying those that could cause the most damage to business operations and deal value. With qualitative assessments, industry insights, and cyber risk quantification, firms can see where their most pressing vulnerabilities lie and focus resources accordingly, enabling CISOs to clearly communicate priority risks to non-technical stakeholders.

• Focus on the Most Effective Controls: In a newly combined organization, not every control will have an equal impact on reducing risk. Evaluating which security measures will be most effective against top risks helps companies avoid unnecessary expenses. By concentrating on the controls that deliver the strongest protection, CISOs can efficiently address vulnerabilities, demonstrating a proactive strategy that resonates with both technical teams and executive leadership.

• Make Data-Driven, High-Impact Decisions: With data-backed insights into risk levels and industry trends, firms can better determine where to invest in cybersecurity to get the best results. Instead of trying to address all risks at once, this approach allows teams to focus on the most critical areas, helping ensure a smoother post-acquisition transition and aligning security measures with business goals.

Combining Cyber Risk Assessments & Quantification

Traditional assessments, such as those using the NIST CSF, provide a qualitative view of a target’s cybersecurity posture, while adding Cyber Risk Quantification (CRQ) translates these risks into financial terms, offering private equity firms a clearer understanding of potential financial impacts. Using frameworks like FAIR™, CRQ highlights the most financially significant vulnerabilities, helping firms make informed decisions that protect deal value.

Combining CRQ with qualitative insights enables a targeted remediation strategy, directing resources to the areas of highest impact. This integrated approach also supports a more effective post-acquisition integration by aligning security efforts with business goals and minimizing operational disruptions. Together, these tools equip firms with a value-driven strategy to address cyber risks comprehensively.
