Cybersecurity Risk During Prolonged Private Equity Hold Periods

Private equity holding periods are getting longer, and that changes the economics of technology and cybersecurity investment.
A portfolio company may enter an investment period with a clear value-creation plan, a defined technology roadmap, and an initial understanding of its cybersecurity risks. But when a five-year hold becomes six, seven, or eight years, those original assumptions begin to age.
Systems reach end of life. New applications are introduced. Add-on acquisitions create complexity. Employees and executives turn over. Vendors gain access to critical environments. Regulatory and customer expectations change.
At the same time, portfolio companies are often being asked to improve margins, reduce operating expense, and protect EBITDA.
That creates a difficult tension for portfolio company leadership:
How do you determine which technology and cybersecurity investments are truly necessary, which can be deferred, and which risks could eventually impair operations, growth, or enterprise value?
The answer is not simply to spend more on cybersecurity. It is to maintain enough visibility to make deliberate investment decisions before risk becomes urgent and expensive.
The Original Cybersecurity Assessment Has a Shelf Life
Cybersecurity due diligence remains important during an acquisition.
Before close, a buyer needs to understand whether security, technology, privacy, or operational issues could affect valuation, integration costs, regulatory exposure, or business continuity.
A typical review may examine areas such as:
· Previous security incidents and data breaches
· Identity and access management
· Aging or unsupported technology
· Software vulnerabilities
· Cloud and network security
· Data protection and privacy obligations
· Third-party and vendor access
· Incident response and business continuity
· Cyber insurance
· Regulatory and contractual requirements
· Security leadership and governance
The purpose is not merely to determine whether the target has the right security tools. It is to understand whether technology or cyber risk could create unexpected costs, interrupt operations, affect customers, or alter the economics of the transaction.
A formal cybersecurity risk and maturity assessment can establish that initial baseline.
But that baseline reflects the company at one moment in time.
As the business changes, so does the risk.
Longer Hold Periods Change the Investment Equation
Private equity firms are holding portfolio companies longer than they have historically.
According to the McKinsey Global Private Equity Report 2026, more than 16,000 companies had been held for at least four years at the end of 2025. Those companies represented 52% of global buyout-backed inventory, up from 43% the prior year.
The average holding period reached 6.6 years, compared with an average of 6.1 years between 2011 and 2020.
EY reported a similar pattern in its 2026 Global Private Equity Exit Readiness Study, finding that approximately 35% of the global private equity portfolio had been held for more than six years.
Those additional years matter.
The longer a company remains in the portfolio, the more likely leadership will face technology and cybersecurity investments that were not contemplated in the original value-creation plan.
A company that completed cybersecurity diligence several years ago may now have:
· Added new cloud platforms and business applications
· Completed one or more add-on acquisitions
· Changed executives, IT leadership, or security providers
· Expanded into markets with different regulatory requirements
· Accumulated aging or unsupported technology
· Increased third-party access to critical systems and data
· Collected significantly more customer and employee information
· Changed its operating model or technology architecture
The issue is not that a longer hold automatically creates a cybersecurity problem.
The issue is that the original assumptions about risk, investment, and acceptable exposure may no longer be valid.
Deferred Investment Eventually Becomes a Business Decision
Technology and security improvements compete with every other investment a portfolio company needs to make.
Replacing aging systems, improving identity controls, reducing critical vulnerabilities, strengthening recovery capabilities, or modernizing infrastructure can often be postponed for a period of time.
But postponement does not always eliminate the cost.
During an extended hold, investments that were reasonable to defer in years one or two may become increasingly difficult to avoid in years five, six, or seven.
The result can be a growing backlog of technology and cybersecurity needs at precisely the time leadership is under pressure to improve margins and control operating expense.
That does not mean every identified security gap deserves funding.
In fact, one of the most important disciplines during a prolonged hold is determining which risks justify investment.
Leadership should be able to distinguish between:
· Risk the business can reasonably accept
· Risk that can be managed through existing processes
· Risk that should be monitored as conditions change
· Risk that requires near-term investment because it could affect operations, customers, growth, or enterprise value
The goal is not maximum cybersecurity spending. It is better clarity about where cybersecurity investment protects or creates value.
Buy-and-Build Can Create Value Faster Than Technology Can Absorb It
Add-on acquisitions are another major source of change during an extended holding period.
Buy-and-build strategies can accelerate growth and increase enterprise value, but each acquisition may also introduce new technology environments, vendors, applications, users, data, and security practices.
The combined organization can quickly inherit:
· Multiple identity platforms
· Different endpoint and security tools
· Separate cloud environments
· Overlapping vendors
· Inconsistent access models
· Redundant applications
· Different network architectures
· Multiple data repositories
· Uneven incident-response capabilities
When integration does not keep pace with acquisition activity, operational complexity increases.
Cybersecurity is one consequence of that fragmentation, but it is not the only one. Complexity can also increase technology cost, slow integration, reduce visibility, and make it harder for leadership to understand where material risk actually exists.
Private equity firms using a buy-and-build strategy may therefore benefit from a repeatable approach to portfolio-wide cyber risk management.
The objective is not to force every portfolio company or acquisition onto identical technology.
It is to create enough consistency to understand critical exposures, investment needs, ownership, and progress.
Accountability Often Becomes Less Clear Over Time
Extended holding periods also create organizational change.
Executives leave. IT leadership changes. Providers are replaced. Business units are reorganized.
New acquisitions introduce different operating models.
Over time, responsibility for cybersecurity can become distributed across IT, legal, compliance, operations, finance, and external vendors.
The result is often not a complete absence of activity. It is a lack of clear accountability.
Known risks may remain unresolved because no executive is clearly responsible for deciding whether the business should accept the risk, fund the solution, or pursue an alternative.
For some portfolio companies, this is primarily a governance problem rather than a technology problem.
Companies that need executive cybersecurity leadership without adding another permanent executive position may use virtual CISO support to connect cybersecurity decisions to budgets, governance, business priorities, and board reporting.
Technology and Cyber Risk Can Become Value-Creation Risk
Cybersecurity is often discussed in terms of breaches, ransomware, and regulatory exposure.
Those risks matter, but the financial impact of technology and cyber risk is broader.
Unexpected remediation, aging infrastructure, insurance requirements, customer security demands, rushed modernization, incomplete acquisition integration, and operational disruption can all consume capital that was not included in the original investment case.
Kroll surveyed more than 300 global private equity executives for its 2026 report on cyber risk in private equity portfolios. The findings included:
· 94% of private equity firms had absorbed losses from cyber-related disruption
· The average financial impact to deals disrupted by cybersecurity risk was approximately $2.1 million
· 13% reported losses exceeding $5 million
A significant cyber event can create downtime, lost revenue, delayed billing, legal costs, customer attrition, insurance disputes, and emergency remediation.
But leadership does not need to experience a major breach for cybersecurity to affect value creation.
The risk may instead appear as an unplanned investment requirement.
A portfolio company approaching exit may discover that a buyer, customer, insurer, lender, or regulator expects capabilities the company has postponed for several years.
At that point, leadership has fewer choices and less time.
What could have been a deliberate investment decision becomes an urgent remediation project.
The Cost of Waiting Can Become Most Visible at Exit
Exit readiness should begin well before a company formally enters the sale process.
EY found that 86% of general partners believed exit-preparation initiatives improved valuation, with the strongest results reported when preparation began 12 to 24 months before the sale.
From a technology and cybersecurity perspective, early preparation allows leadership to identify issues while there is still time to decide how to address them.
An exit-ready company may be able to demonstrate:
· A current understanding of material technology and cyber risks
· Clear ownership and executive oversight
· A history of risk reduction and investment decisions
· Current policies and assessments
· Vulnerability and remediation history
· Penetration-testing results
· Incident and insurance history
· Data protection and privacy documentation
· Third-party risk records
· Business-continuity and recovery testing
· Evidence that significant identified risks were resolved, mitigated, or formally accepted
This documentation does more than prove that cybersecurity activities occurred.
It reduces uncertainty.
That matters because unresolved risk discovered during a transaction can give a buyer reasons to request remediation, delay closing, seek stronger contractual protections, or challenge valuation.
Managing Technology and Cyber Investment Across an Extended Hold
A stronger approach treats the original acquisition assessment as a starting point for ongoing investment decisions.
At acquisition: What risk are we inheriting?
Pre-close assessment should identify technology and cybersecurity issues capable of affecting valuation, continuity, regulatory exposure, integration requirements, or near-term investment.
Leadership should understand which issues require action before close and which should become part of the value-creation plan.
During value creation: What deserves investment now?
Once the company is operating under new ownership, the focus should move from identifying every possible gap to prioritizing the risks that matter most.
Leadership should be able to answer:
· Which risks could materially disrupt operations?
· Which could affect customers or revenue?
· Which investments are necessary to support growth?
· Which risks can reasonably be accepted?
· Which improvements can be deferred?
· Where could delaying action create a more expensive problem later?
This is where cybersecurity becomes a capital-allocation discipline.
After significant business change: Have the assumptions changed?
Risk should be reconsidered after events that materially alter the business.
Examples include:
· Add-on acquisitions
· Cloud migrations
· New products
· Geographic expansion
· Regulatory changes
· Leadership turnover
· Major technology transformations
· New critical vendors
· Significant customer requirements
These events can change the company's risk profile enough that previous assumptions should be revisited.
ACA Group's analysis of more than 300 portfolio companies found that companies with sustained oversight tended to cluster toward lower-risk categories. The strongest relationships were associated with governance, reviewed policies, executive oversight, and updated incident-response and business-continuity plans. Read the ACA portfolio cyber-risk findings.
Companies without sufficient internal resources may also use managed cybersecurity services to support vulnerability management, compliance, security operations, and ongoing program oversight.
Ahead of exit: What could create buyer uncertainty?
The final question should not be whether the portfolio company can produce a cybersecurity checklist.
It should be whether unresolved technology or cyber risk could create friction in the transaction.
Issues identified early can be addressed deliberately.
Issues discovered late can become expensive.
The Objective Is Better Investment Clarity
Longer private equity hold periods create a difficult operating reality.
Portfolio companies may need to continue investing in technology, cybersecurity, integration, and resilience while simultaneously being asked to reduce operating costs, improve margins, and prepare for an eventual exit.
Those objectives are not necessarily incompatible.
But they require better information.
The question is not whether every portfolio company should spend more on cybersecurity.
The question is whether leadership can identify which investments are necessary, which risks are acceptable, and where delaying action could create a larger financial or operational problem later.
As holding periods extend, that distinction becomes increasingly important.
A pre-acquisition cybersecurity assessment can establish an initial understanding of risk. It cannot tell leadership what the company will need five years later.
Maintaining visibility throughout the investment period allows portfolio company executives and private equity sponsors to make those decisions deliberately rather than reactively.
The goal is not continuous cybersecurity diligence for its own sake. It is continuous confidence that technology and cyber investment is aligned with operational performance, value creation, and the eventual exit.
