Cybersecurity Due Diligence And Technology Risk For M&A

Reduce deal risk, uncover hidden liabilities, and avoid costly surprises before and after close.

Cyber Risk Should Never Be Discovered After The Deal Closes

In today’s deal environment, technology and cybersecurity risk can materially impact valuation, integration timelines, and post-close outcomes. Undiscovered security gaps, unmanaged technical debt, or unresolved incidents can quickly become costly liabilities.

Natsar provides independent, deal-focused cybersecurity due diligence—primarily supporting buy-side teams—so investors and advisors understand what they’re acquiring, where the real risks sit, and what remediation will cost in time and dollars.

We translate complex technical findings into clear, actionable insight for deal teams, executives, boards, attorneys, and insurers—so decisions are made with confidence before and after close.

When Organizations Engage Natsar For M&A Support

Organizations typically engage Natsar when they need independent cyber and technology risk insight during critical deal moments, including:

  • Evaluating cybersecurity and technology risk prior to issuing or finalizing a letter of intent (LOI)

  • Conducting confirmatory diligence during deal execution

  • Assessing whether cyber risk should impact valuation, representations and warranties, or deal structure

  • Preparing leadership and boards for acquisition-related risk decisions

  • Planning post-close integration, remediation, and governance improvements

  • Supporting attorneys, insurers, or advisors who need independent cyber risk insight

Who This Is For

This service is designed for:

  • Private equity firms and investment teams evaluating acquisition risk

  • Corporate development teams supporting strategic transactions

  • Attorneys and deal advisors who need independent cyber risk insight

  • Insurance stakeholders supporting cyber-related underwriting or deal requirements

  • Executives and boards seeking a clear view of material technology and cyber risk before approval

A Practical, Deal-Focused Approach To Cyber Due Diligence

Natsar’s M&A support goes beyond checklist-driven diligence. We focus on how cybersecurity and technology risk affects real-world outcomes—financial, operational, regulatory, and reputational.

This approach prioritizes:

  • Material risk identification over volume of findings

  • Clear, decision-ready insight over technical noise

  • Practical remediation planning over theoretical compliance

Where appropriate, we align assessments to recognized frameworks such as NIST CSF and CIS Controls—providing structure without slowing the deal.

Common Cyber And Technology Red Flags In M&A Transactions

Across M&A engagements, we frequently identify issues that materially impact deals, including:

  • No documented security governance, policies, or defined accountability

  • No incident response plan or evidence of incident readiness

  • Lack of visibility into systems, assets, or data flows

  • No centralized logging, monitoring, or detection capabilities

  • Absence of endpoint protection, network security, or mobile device management

  • No alignment to any recognized security framework

  • Significant technical debt and unaddressed vulnerabilities

  • Poor identity, access, and privilege management

  • No ability to confidently determine whether the environment is currently compromised

These conditions often lead to deal repricing, delayed closes, increased insurance scrutiny, or costly post-close remediation.
