SecureMerge – Cyber Risk Management for Mergers & Acquisitions (M&A)

📌 Project Overview

SecureMerge is a cybersecurity and Governance, Risk, and Compliance (GRC) framework designed to manage cyber risks throughout the Mergers & Acquisitions (M&A) lifecycle.

The project addresses challenges faced by parent organizations that frequently acquire smaller companies such as SaaS startups or regional service providers, where hidden cyber risks are common (legacy systems, unknown breaches, weak security controls, and compliance gaps).

The framework covers:

• Pre-deal cyber due diligence
• Post-deal integration and isolation decisions
• Long-term governance and inherited risk tracking

---

🎯 Objectives

• Define a repeatable cyber due diligence process for acquisition targets
• Align acquired entities with the parent company’s security policies and risk appetite
• Govern integration decisions:
  • Connect
  • Isolate
  • Ring-fence
  • Rebuild (clean-room)
• Track inherited cyber risks and remediation progress over time
