Cybersecurity Due Diligence Software

Cybersecurity risk is one of the most consequential — and most frequently underassessed — dimensions of M&A due diligence. Acquirers inherit not only a target's technology, but also its security vulnerabilities, compliance obligations, and incident history.

Cybersecurity due diligence software provides structured, repeatable assessments of security posture, helping investors quantify cyber risk before it becomes a post-close liability.

Diligenze integrates cybersecurity assessment into its AI-native technology diligence platform, giving deal teams a unified view of technology and security risk.

Why This Matters in M&A

High-profile breaches discovered post-acquisition have cost acquirers hundreds of millions in remediation, regulatory fines, and lost enterprise value. Identifying cybersecurity risks during diligence — not after closing — is essential to protecting deal value and managing integration risk.

Common Challenges

  • Unknown security vulnerabilities inherited through acquisitions
  • Compliance gaps across GDPR, SOC 2, HIPAA, and ISO 27001
  • Lack of visibility into the target's incident response maturity
  • Data protection risks that create regulatory and reputational exposure
  • No standardised approach to assess security posture across deals

How Diligenze Helps

Diligenze evaluates cybersecurity maturity across access controls, vulnerability management, data protection, encryption, incident response, and third-party risk. Assessments are aligned to CIS Controls, NIST Cybersecurity Framework, SOC 2, and ISO 27001.

The platform produces structured risk reports with evidence-linked findings, enabling investment committees to make informed decisions. Post-close, the same assessments drive remediation roadmaps and security improvement plans.

  5. 5Generate cybersecurity risk reports with evidence-linked findings

Frequently Asked Questions

What is cybersecurity due diligence?
Cybersecurity due diligence is the assessment of a target company's security posture, controls, and risk exposure during an M&A transaction. It identifies vulnerabilities, compliance gaps, and incident response readiness that could affect deal value.
Why is cybersecurity due diligence important in M&A?
Acquiring a company means inheriting its security risks. Undisclosed breaches, weak controls, or regulatory non-compliance can result in financial losses, legal liability, and reputational damage post-close.
What frameworks are used in cybersecurity due diligence?
Common frameworks include CIS Controls, NIST Cybersecurity Framework, SOC 2, ISO 27001, HIPAA, and PCI DSS. The appropriate framework depends on the target's industry and regulatory environment.
How long does cybersecurity due diligence take?
Traditional cybersecurity diligence takes 3-6 weeks. With AI-powered tools like Diligenze, initial risk assessments can be completed in days, with detailed analysis following in 1-2 weeks.
What does Diligenze assess in cybersecurity diligence?
Diligenze evaluates access controls, vulnerability management, data protection, encryption practices, incident response maturity, third-party risk, and compliance with relevant regulatory frameworks.
