Private equity firms are known for their ruthless efficiency: cutting costs, restructuring balance sheets, juicing margins, and plotting swift, profitable exits. But as capital has become commoditised and digital risk has grown, a new lever of operational value has emerged—not in headcount or cash flow, but in code. Cybersecurity, long viewed as a compliance burden, is now an investment thesis in disguise. The firms that learn to lead on digital resilience—particularly within their portfolio companies—will not only protect enterprise value but may discover a new dimension to build it.
The challenge is both urgent and obvious. Across industries, cyber risk has metastasised from nuisance to existential threat. Ransomware is rampant, state actors are increasingly targeting private firms, and third-party vulnerabilities now expose entire ecosystems. According to IBM’s 2024 Cost of a Data Breach report, the average incident in the United States costs over $9.4 million. Meanwhile, PwC reports that less than 40% of middle-market firms—a sweet spot for private equity—have implemented baseline cyber defences.
Cybersecurity, in short, has become a board-level concern. And yet, in the fast-moving world of PE, it is too often overlooked during diligence, underfunded in early ownership, and left to the discretion of overwhelmed portco executives. That is not only risky—it is shortsighted.
Due Diligence in the Digital Age
Most private equity diligence processes remain focused on the tangible and the traditional: quality of earnings, legal exposure, tax structure, and growth trajectory. But increasingly, it is the intangible infrastructure—the APIs, the cloud misconfigurations, the legacy endpoints—that presents the most material risk.
Savvier firms are expanding their due diligence lens to include formal cyber assessments, penetration testing, and even dark web exposure scans. This is not just about hygiene—it is about valuation accuracy. Consider the firm that acquires a target for 10x EBITDA, only to learn six months later that it harboured a latent vulnerability now exploited by ransomware. The result? A degraded asset, a distressed balance sheet, and a liability that never made the pro forma.
Cyber due diligence should thus be viewed as asset-level insurance, priced in time, not premium. It can reveal hidden liabilities, reduce overpayment, and better calibrate post-acquisition investment needs.
Post-Acquisition: From Policy to Platform
After acquisition, most PE firms implement a 100-day plan: new leadership, tighter controls, maybe an ERP rollout. Rarely, however, does cybersecurity receive the same standardised treatment. It should.
A platform-level cybersecurity playbook—spanning identity governance, cloud controls, endpoint protection, and incident response—can be deployed across the portfolio with economies of scale. Not only does this create risk consistency across assets, but it also allows for shared procurement savings, common KPIs, and centralized threat intelligence.
Indeed, one of the untapped synergies of PE portfolios is the opportunity to build collective cyber resilience. Imagine a scenario in which portfolio companies share a Security Operations Center (SOC), or pool data to train AI-driven threat detection systems. In this way, the general partner becomes not just a capital allocator but a force multiplier for cyber defence.
Capital Efficiency and Cyber ROI
Private equity is, above all, an asset class obsessed with return on investment. Cybersecurity investments often fail to excite, largely because they are framed as cost centres or insurance policies. But this framing misses the point.
Cyber initiatives, if intelligently deployed, can preserve exit value, reduce regulatory exposure, and accelerate revenue recovery after incidents. According to research from Deloitte, companies that suffer a significant breach face a market capitalisation impact of up to 15% over the subsequent year. For a portfolio under a 5-year hold with a 2x MOIC target, this is not just inconvenient—it is catastrophic.
Smart firms are beginning to model expected loss curves from cyber events and calculate capital-at-risk based on asset class, industry exposure, and threat surface. The result is an actuarial framework for cyber investment, one that can be measured, monitored, and managed.
The Regulator at the Door
Private equity is not immune from the rising tide of regulation. In late 2023, the U.S. Securities and Exchange Commission introduced new rules mandating public companies to disclose “material cybersecurity incidents” within four business days. While private companies are not yet bound by the same rules, many portfolio companies prepare for IPOs or strategic sales—transactions that increasingly involve cyber scrutiny.
In Europe, the Digital Operational Resilience Act (DORA) and the updated NIS2 Directive demand even more rigorous standards for companies operating critical services. A portfolio company in energy, healthcare, or logistics may find itself subject to these rules regardless of ownership structure.
PE firms would be wise to treat regulatory readiness as value creation, not overhead. Firms that can demonstrate cyber maturity at exit will likely benefit from smoother transactions, higher multiples, and fewer post-closing liabilities.
Talent, Tools, and Transformation
Of course, none of this is possible without the right talent. And therein lies the rub. Cybersecurity professionals are expensive, scarce, and often reluctant to work for companies without a meaningful tech charter. PE firms can counter this by building in-house security operating teams, akin to operating partners in finance, sales, or supply chain.
These teams can help portcos mature their cybersecurity practices through structured assessments, technology roadmaps, and policy templates. More ambitiously, some firms are experimenting with Cyber Operating Platforms—central repositories of tools, shared vendor contracts, benchmarks, and incident playbooks.
As AI further proliferates across business functions, the attack surface expands. Large Language Models, automation workflows, and smart APIs all introduce new vulnerabilities. PE firms must get ahead of this trend by building cyber awareness not only into the CIO’s office but into every digital transformation initiative they fund.
Culture and the Exit Premium
The ultimate measure of cyber success is not compliance but culture. A portfolio company that treats cybersecurity as a strategic function—one that embeds it into product development, customer trust, and business continuity—is more likely to succeed in competitive and regulated markets.
Cyber maturity can even create exit premiums. Strategic buyers increasingly value targets with robust digital hygiene, particularly in sensitive sectors like fintech, healthcare, and logistics. A seller that can demonstrate audit trails, tested incident response plans, and third-party certifications (e.g., ISO 27001, SOC 2) can command valuation advantages.
For PE firms, this is the final arbitrage: transforming cybersecurity from a sunk cost to a differentiated asset.
Closing the Gap
Private equity has always thrived on asymmetry—knowing what others don’t, acting faster, managing better. Cybersecurity presents a new frontier for such asymmetry. It is still under-addressed, under-funded, and under-strategised in most buyouts. But it is also increasingly underwritten in enterprise value.
The firms that move first—embedding cyber into diligence, post-acquisition planning, and operational governance—won’t just avoid costly breaches. They will build better businesses, command higher exits, and future-proof their portfolios against the defining risk of the digital age.
In an era where code is capital and trust is transactional, cybersecurity is no longer optional. It is operational alpha.
