Cybersecurity Budget Benchmarks 2026: PE Portfolio Company Spending

Cybersecurity spending in PE-backed companies occupies a distinctive position. The value creation imperative demands capital discipline, yet underinvestment in security creates risk that can materially affect exit valuations. The challenge is not maximising spend but optimising it — allocating resources to controls that demonstrably reduce the risks most relevant to the business and its regulatory environment.

Revenue-Based Spending Benchmarks by Sector

Industry data for 2026 indicates that cybersecurity spending as a percentage of revenue continues to vary significantly by sector, reflecting differing regulatory requirements, data sensitivity, and threat exposure. Financial services firms typically allocate between 0.6 and 1.2 percent of revenue to cybersecurity, driven by DORA^[1], NIS2^[2], and supervisory expectations from national financial regulators. Healthcare and life sciences organisations spend between 0.5 and 0.9 percent, reflecting the sensitivity of patient data and the operational criticality of connected medical systems.

Technology and software companies, where intellectual property protection and customer data security are existential concerns, typically invest 0.8 to 1.5 percent of revenue. Manufacturing and industrial companies have historically lagged at 0.3 to 0.6 percent, though NIS2 obligations are driving significant upward pressure for entities classified as essential or important. Professional services and consulting firms generally fall between 0.4 and 0.8 percent, with higher allocations for those handling sensitive client data.

These ranges should be interpreted cautiously. Revenue percentage alone is an imperfect proxy — a high-margin software company and a low-margin distributor with identical revenue may have vastly different absolute security needs. More sophisticated benchmarking considers cybersecurity spend per employee, per managed endpoint, and as a proportion of total IT expenditure. The latter metric typically falls between 12 and 18 percent for well-resourced organisations and below 8 percent for those with significant maturity gaps.

Board Reporting on Security Budgets

Effective board reporting on cybersecurity investment requires translating technical expenditure into business risk terms. The most productive frameworks present security spending in three dimensions: compliance-driven investment required to meet regulatory obligations (NIS2, GDPR^[3], DORA, sector-specific requirements), risk-driven investment that reduces quantified exposure to the threats most relevant to the business, and capability-driven investment that builds or maintains security operations maturity.

This taxonomy enables boards to evaluate trade-offs explicitly. Compliance expenditure is largely non-discretionary — the question is efficiency of implementation, not whether to invest. Risk-driven expenditure can be evaluated against quantified risk reduction, enabling return-on-investment analysis that investment professionals find intuitive. Capability investment is strategic, building organisational resilience that underpins both compliance and risk management over the medium term.

Boards should expect quarterly reporting that tracks budget execution against plan, maps expenditure to these three categories, and reports key risk metrics that demonstrate the effectiveness of investment. Metrics should include mean time to detect and respond to incidents, vulnerability remediation rates, compliance status against applicable frameworks, and third-party risk assessment coverage.

Investment Priority Framework for 2026

For portfolio companies evaluating where to allocate incremental cybersecurity budget, the priority framework for 2026 reflects the current threat and regulatory landscape. NIS2 compliance investment is the leading priority for newly in-scope entities — the registration, risk assessment, and incident reporting capabilities required by the directive represent mandatory expenditure that should be funded before discretionary improvements.

Identity and access management modernisation continues to deliver strong risk reduction per euro invested. Implementing multi-factor authentication across all privileged and remote access, combined with privileged access management for critical systems, addresses the attack vector responsible for the majority of successful breaches. For portfolio companies that have not yet implemented these controls comprehensively, this represents the highest-impact discretionary investment.

Detection and response capability — whether through managed detection and response services, security operations centre as a service, or internal SOC investment — is the third priority. The regulatory expectation under NIS2 for rapid incident detection and reporting makes this both a compliance and operational necessity. For mid-market portfolio companies, managed services typically provide superior capability at lower total cost than building internal capacity.

The Underinvestment Risk at Exit

Cybersecurity underinvestment creates a specific risk for PE portfolios at exit. Buy-side cyber due diligence is now standard practice in mid-market and large-cap transactions, and material security deficiencies discovered during diligence directly affect valuation. Remediation cost estimates are deducted from enterprise value, and in cases where deficiencies raise questions about data integrity or regulatory compliance, the impact extends beyond direct remediation to risk-adjusted valuations of the underlying business.

The economics are asymmetric: proactive investment in cybersecurity during the hold period is materially less expensive than the valuation discount applied when deficiencies surface during a sale process. A portfolio company that invests appropriately in security maturity over a three-to-five-year hold period exits with a demonstrably lower risk profile — a tangible value creation lever that sophisticated buyers recognise and price accordingly.

Practical Guidance for Investment Teams

Investment teams should incorporate cybersecurity budget benchmarking into portfolio monitoring as a standing practice. Request quarterly cybersecurity budget reports from portfolio company management, benchmarked against sector peers. Ensure that security investment is tied to a risk-based roadmap approved at board level, not driven reactively by incidents or vendor sales cycles.

For new acquisitions, the first 100-day plan should include a cybersecurity maturity assessment and a costed remediation roadmap. This baseline enables informed budget allocation from the outset of the hold period, rather than discovering gaps during exit preparation when remediation is more expensive and time-constrained. The benchmark data presented here provides a reference point, but the optimal budget for any specific portfolio company depends on its unique risk profile, regulatory obligations, and strategic trajectory.
