M&A Due Diligence Process

Undisclosed breaches, regulatory non-compliance, and technical debt represent quantifiable liabilities that transfer directly to the acquirer upon closing. Conventional financial due diligence rarely examines technology infrastructure with the depth required to surface these exposures, leaving acquirers to inherit cyber liabilities that erode returns and require unplanned capital expenditure.

Intarmour's process is designed to operate within compressed competitive auction and bilateral negotiation timelines, delivering actionable intelligence at each phase without sacrificing rigour. Every engagement follows six phases, adapted in scope and depth to the transaction and target company risk profile.

This methodology is the foundation of our Technical Due Diligence capability — governing engagement, assessment, quantification, and client support. The result is consistent, defensible cyber risk assessment integrating seamlessly with financial models, warranty negotiations, and investment committee reporting.

Three parallel workstreams — data room review, management interviews, and external reconnaissance — ensure efficient use of the assessment window while allowing findings from each to inform the others.

Data room access provides the documentary foundation: security policies, network architecture, asset inventories, vulnerability and penetration testing reports, incident response plans, business continuity documentation, compliance certifications, third-party audit reports, and insurance details. Documentation completeness itself is a diagnostic indicator of security maturity.

Management interviews follow a structured protocol with CIO, CISO, Head of IT Operations, DPO, and business unit leaders, covering governance, incident history, investment priorities, known vulnerabilities, third-party risk, and regulatory compliance. Findings are cross-referenced with documentary evidence and reconnaissance results to identify discrepancies.

External reconnaissance operates independently: domain infrastructure analysis, exposed service enumeration, SSL/TLS certificate mapping, credential leak monitoring, DNS analysis, and technology stack identification. This frequently surfaces material findings absent from internal documentation.

Technical findings are transformed into financial terms for investment committees and legal counsel: a quantified view of cyber liability informing purchase price adjustments, warranty provisions, and post-acquisition capital planning.

Financial impact modelling estimates monetary exposure: breach notification costs based on data volume and sensitivity, regulatory penalty exposure using enforcement precedent analysis, business interruption costs modelled against revenue dependencies, remediation costs for technical debt, and reputational impact. Each estimate includes probability-weighted scenarios — base, adverse, and severe but plausible — for financial model integration.

Remediation cost estimation provides itemised projections covering technology, implementation, personnel, and ongoing operational costs, organised by priority tier: critical remediations for immediate post-close action versus improvements sequenced over twelve to twenty-four months. This feeds directly into value creation planning and the hundred-day agenda.

Probability assessment considers sector threat profile, control maturity, historical incident data, technology-specific threat intelligence, and regulatory enforcement trends. Combined with impact modelling, this produces expected-loss calculations translating into purchase price adjustment recommendations and warranty indemnification quantum.

The assessment extends beyond report delivery, ensuring findings are effectively communicated and the commissioning party has context to act on recommendations.

We present findings directly to the investment committee, translating technical analysis into the risk-return framework governing investment decisions: implications for valuation, warranty negotiation considerations, remediation investment requirements, and comparative benchmarking. We prepare for the full range of committee questions, from specific vulnerabilities to strategic competitive implications.

Post-delivery, we remain available for follow-up: clarification for legal counsel drafting warranties, additional risk category analysis, updated assessment if new information emerges, and coordination with other diligence workstreams. Support extends through transaction completion and, where the client proceeds, transitions into Post-Merger Security Integration planning.

For ongoing portfolio management, post-delivery support may extend into a continuing relationship governed by our Advisory Engagement Approach, ensuring continuity between transaction assessment and portfolio-level security governance. Intelligence from pre-acquisition assessment directly accelerates post-close improvement, eliminating information loss from separate advisory engagements.
