Cyberattacks Cost PE Deals $2.1M, Exposing a Mid-Market Blind Spot

NEW YORK, NY – February 11, 2026 – A silent but costly threat is derailing private equity deals and eroding portfolio value, with cyberattacks now inflicting an average financial impact of $2.1 million per incident, according to a new global report by risk advisory firm Kroll. The findings reveal that cybersecurity has evolved from a back-office IT issue into a material risk that directly threatens deal flow and valuations across the investment lifecycle.

The report, "Cyber Risk at Scale: Safeguarding Portfolio Value in Private Equity," surveyed 325 PE executives and found that the consequences of a breach are both widespread and severe. A staggering 94% of firms reported suffering some financial impact from cyber risk. For over a quarter of firms (26%), this translated directly into a reduced valuation or a lower exit price for a portfolio company.

The High Cost of Digital Negligence

The $2.1 million average cost is just the beginning of the story. The research indicates a 53% probability that a single cyber incident will cost a firm more than $500,000, and a concerning 13% chance that the financial fallout will exceed a staggering $5 million. These figures align with broader industry data showing the average cost of a data breach across all sectors reached an all-time high of $4.45 million in 2023.

"Cybersecurity has evolved into a material transaction risk, becoming a direct threat to deal flow and valuation in private equity," said Dave Burg, Global Group Head of Cyber and Data Resilience at Kroll, in the report's release. He emphasized that the direct costs are merely the "tip of the iceberg."

The true costs, Burg noted, emerge later in the form of regulatory investigations, deal timeline delays, and reputational damage. The report details that beyond direct financial loss, 80% of PE firms have experienced operational disruption during the hold period. This includes unexpected remediation costs (44%), business disruption or downtime (27%), and compliance or regulatory-related litigation (29%).

Adding to the pressure, attackers are becoming more sophisticated. "Attackers are increasingly synchronizing when they strike and are using generative AI to amplify the impact and effectiveness of their actions," Burg added. This escalating threat landscape means that past performance is no guarantee of future security, forcing firms to constantly re-evaluate their defensive posture.

A Tale of Two Tiers: The Mid-Market's Cyber Blind Spot

The Kroll study uncovers a dramatic divide in cyber preparedness between the industry's giants and its smaller players. A clear "maturity gap" exists between larger firms (with over $25 billion in assets under management) and their mid-market and smaller counterparts.

This disparity is evident across governance, diligence, and resources:
* Governance: 55% of larger firms govern cyber risk through a formal mandate to portfolio company managers, a practice adopted by only 12% of smaller firms.
* Due Diligence: Cybersecurity due diligence is a standard part of the transaction process for 81% of large firms, but for just 29% of smaller firms.
* Leadership: Over half (52%) of large firms have a dedicated cyber risk leader, compared to a mere 15% of smaller firms.

Instead of dedicated platforms and in-house leadership, smaller firms are far more likely to rely on manual monitoring (50%) and managed service providers (53%). While external support is valuable, this approach can leave them more exposed to significant remediation costs and deal-killing disruptions if not managed within a structured internal framework.

"Cybersecurity incidents can cause significant impacts to private equity portfolios of all sizes, making a focused and disciplined approach essential across the industry for firms to protect and maximize value," stated Eric Hasty, Managing Director of Cyber and Data Resilience at Kroll. "Our study shows that PE firms that implement a concise set of required cybersecurity controls, leverage dedicated platforms to monitor risk, conduct standardized diligence and establish clear accountability are far more effective at protecting value against cyber exposure in a cost–efficient manner."

From Checkbox to Cornerstone: The New Regulatory Reality

The pressure to address cybersecurity is no longer just coming from sophisticated hackers or nervous investors; it is being codified into law. A rapidly evolving regulatory landscape, led by the U.S. Securities and Exchange Commission (SEC), is transforming cyber risk from a best practice into a legal and fiduciary imperative.

New SEC rules, with compliance deadlines beginning in late 2025, are set to fundamentally alter how private fund managers handle cybersecurity. The regulations mandate that firms establish comprehensive incident response programs to detect and recover from breaches. Critically, firms will be required to notify the SEC of significant incidents within 48 hours and inform affected individuals within 30 days.

Perhaps most significantly, the new rules demand board-level oversight of cybersecurity programs, ensuring that accountability rests at the highest levels of the firm. This shift prevents cyber risk from being siloed within the IT department and forces its integration into the firm's core strategic and financial planning. These domestic regulations are complemented by stringent international rules like Europe's GDPR and California's CCPA/CPRA, which carry severe financial penalties for non-compliance and impact any firm with a global footprint or customer base.

Future-Proofing Portfolios in an Era of Escalating Threats

In response to these financial, operational, and regulatory pressures, the most forward-thinking private equity firms are beginning to treat cybersecurity not as a liability to be mitigated, but as a potential source of value and competitive advantage. A portfolio company with a demonstrably robust security posture is inherently less risky and more attractive to future buyers, potentially commanding a higher valuation at exit.

This strategic shift is reflected in investment trends, with private equity and venture capital investment in the cybersecurity sector itself nearly doubling to $8.51 billion in the year leading up to May 2024. Firms are not only protecting their own assets but are also capitalizing on the universal need for better security solutions.

Looking ahead, the challenge is only set to grow. An overwhelming 96% of PE executives surveyed by Kroll expect the importance of portfolio cybersecurity to increase over the next 12 months. More than half anticipate that the financial impact of attacks will grow (53%) and that incidents will become more challenging to manage (54%). As the industry prepares for an expected rebound in deal activity, the ability to effectively assess, manage, and govern cyber risk will be a defining characteristic of the most successful firms.
