What is M&A Cyber Due Diligence?

M&A Cyber Due Diligence is the structured evaluation of a target company’s cybersecurity posture, resilience, and exposure before, during, or after a transaction. It assesses the maturity of their controls, governance, and risk management to determine how cyber risk may impact valuation, compliance, or integration.

Rexon Cyber’s due diligence engagements combine technical assessments with strategic business insight. We evaluate the target’s security architecture, data governance, compliance alignment, and historic incidents — translating findings into financial and operational risk metrics investors can act upon.

For private equity, venture capital, and corporate acquirers, this service provides independent, expert assurance that your investment is protected against hidden cyber liabilities.

Why M&A Cyber Due Diligence Matters

Cyber risk has become a defining factor in modern deal-making. A single undisclosed breach or weak control environment can lead to regulatory fines, customer loss, or operational disruption — eroding post-acquisition value overnight.

Traditional financial or legal due diligence often overlooks these risks. Rexon Cyber’s M&A Cyber Due Diligence bridges that gap — providing a clear, evidence-based view of a target’s cyber maturity, exposure, and remediation costs.

Benefits of M&A Cyber Due Diligence

  • Identify hidden cyber risks before acquisition or investment
  • Quantify potential financial and regulatory impact of cyber weaknesses
  • Validate security claims made by the target organisation
  • Support deal negotiations and post-acquisition integration
  • Demonstrate investor due diligence and governance to LPs and regulators
  • Align with NIST, ISO 27001, and DORA frameworks for cyber risk assessment

How Rexon Cyber Delivers

Rexon Cyber’s due diligence process is fast, discreet, and tailored to the transaction timeline. We combine open-source intelligence (OSINT), technical scanning, and policy review to deliver a complete risk picture.

Our process includes:

  1. Initial Review: High-level OSINT and data exposure analysis
  2. Technical Assessment: Targeted vulnerability, cloud, and configuration reviews
  3. Governance Evaluation: Policies, frameworks, and compliance mapping
  4. Incident & Breach Review: Analysis of past incidents or ongoing risks
  5. Risk & Value Analysis: Quantifying remediation costs and impact on valuation

Each engagement delivers a clear, investor-ready report with a Cyber Risk Score, detailed findings, and a prioritised remediation plan — supported by executive summaries suitable for deal teams and boards.
