Cybersecurity in M&A: Due Diligence Templates, Negotiation Tips & Top Products
Updated Sep 12, 2025
Why Cybersecurity Matters in M&A
Unaddressed cybersecurity vulnerabilities can result in data breaches, regulatory fines, IP theft, and reputational damage for both acquirer and target. A thorough cyber risk assessment helps estimate integration costs, reveal risks, and maximize deal value. Early diligence prevents post-deal surprises and enhances compliance with data privacy regulations.
Poor cyber hygiene can expose the acquiring organization to existing or emerging threats, as seen in high-profile cases like Marriott-Starwood.
Cybersecurity’s scope includes both in-house risks and those posed by third-party vendors, cloud environments, legacy systems, and employee behavior.
Tech Due Diligence Checklist and Templates
Effective due diligence should be systematic, covering these core areas:
Business strategy alignment: SWOT analysis, revenue model, competitive landscape.
Organizational assessment: Skills, team structure, recruitment, satisfaction, retention.
Software and technology: Codebase quality, scalability, technical debt, integrations.
Data security: Encryption, access controls, privacy compliance, IP ownership.
IT infrastructure: Cloud/on-prem deployment, resilience, scalability, disaster recovery.
Cybersecurity policy: Incident history, risk management plans, past breaches, compliance certifications.
Vendor review: Security posture of key third-party providers.
High-performing SEO resources should provide downloadable, editable templates for checklists and playbooks.
Negotiation Tips for Secure Transactions
Cybersecurity issues must be proactively addressed in negotiations to mitigate risk and strengthen deal terms:
Begin cyber due diligence as early as possible, ideally during initial deal discussions.
Include cyber risk representations, warranties, and indemnities in contracts.
Negotiate remediation timelines for discovered vulnerabilities pre-close.
Integrate teams promptly; align controls, monitoring, and training between merging organizations.
Plan for incident response coordination in case of breaches discovered post-deal.
