Fractional CISO for Private Equity Portfolios
Protecting portfolio companies across your investment lifecycle - from due diligence to exit
Cybersecurity Leadership for Private Equity
Private equity firms face a unique cybersecurity challenge: managing cyber risk across dozens of portfolio companies with varying maturity levels, often without the in-house expertise to do so effectively. A single breach at one portfolio company can cascade across your entire fund, damaging multiple investments and threatening your reputation with LPs.
Cyber risk has become a deal-breaker in M&A. Acquirers increasingly scrutinise security postures during due diligence, and significant vulnerabilities can lead to purchase price reductions, escrow holdbacks, or deal abandonment. For PE firms, this means cybersecurity directly impacts exit multiples and fund returns.
Yet most portfolio companies lack the resources for a full-time CISO, and PE operating partners rarely have deep cybersecurity expertise. This gap leaves portfolio companies exposed and your investments at risk. Our fractional CISO service provides portfolio-wide security leadership at a fraction of the cost of multiple full-time hires.

Flexible engagement models that scale across your portfolio. One CISO can oversee multiple companies, reducing cost while ensuring consistent security standards.
When Portfolio Companies Are Compromised
Real incidents where PE-backed companies suffered breaches that eroded deal value
Verizon-Yahoo Deal (2017)
$350M price reduction post-breach discovery
Verizon reduced its acquisition price by $350 million after discovering Yahoo's massive data breaches during due diligence. For PE firms, this demonstrates how hidden cyber liabilities can destroy deal value overnight.
Brookfield-CDK Global (2024)
Ransomware disrupted operations post-acquisition
CDK Global, acquired by Brookfield Business Partners in 2022, suffered a major ransomware attack in June 2024 that disrupted automotive dealership operations nationwide. The incident demonstrated how portfolio companies remain vulnerable to cyber attacks that can damage investment value.
Addison Healthcare (2023)
PE-backed firm shut down post-breach
This private equity-backed healthcare provider was forced to close after a ransomware attack destroyed its operations. Without adequate cyber insurance and incident response planning, the fund lost its entire investment.
M&A Cyber Due Diligence Failure
$50M+ in hidden remediation costs
A mid-market PE firm acquired a software company only to discover post-close that critical security vulnerabilities required $50M+ in remediation. Proper technical due diligence would have identified these issues before closing.
SolarWinds Supply Chain (2020)
Multiple PE portfolio companies affected
The SolarWinds attack demonstrated how supply chain compromises cascade through portfolios. PE firms with portfolio-wide security visibility were able to respond faster and limit damage.
LP Due Diligence Pressure
Fundraising challenges for GP
An increasing number of LPs now require detailed cybersecurity disclosure during fundraising. PE firms without portfolio security programmes struggle to demonstrate adequate risk management to institutional investors.
Critical Risks Facing Private Equity
The cyber threats that threaten portfolio value and fund returns
Deal Value Erosion
Undisclosed cyber vulnerabilities discovered during due diligence can lead to price reductions, escrow holdbacks, or deal collapse.
Portfolio Contagion
Shared infrastructure, common vendors, and interconnected systems mean one breach can spread across multiple portfolio companies.
Ransomware Extortion
PE-backed companies are prime ransomware targets - attackers know portfolio companies have capital to pay and cannot afford operational disruption.
Regulatory Exposure
GDPR, sector-specific regulations, and emerging cyber disclosure requirements create compliance burdens across portfolio companies.
