Cyber Security Due Diligence For Mergers & Acquisitions (M&A)

Due Diligence to Protect Your Investments

A Closer Look

Understanding the risk and security profile of a target company is essential. To prepare for an acquisition (M&A), target companies reduce expenses and maximize profits to look more attractive and increase their value. The acquiring organization must determine what liabilities or risks can arise under the target company’s cyber security program.

Due Diligence through Risk Profiling

Compromise Assessment Hunt for indicators of current malicious and suspicious behaviors. Determine if there are Indicators of Compromise (IoC) and their severity.

Security Architecture Review Review design of critical security controls and overall architecture. Discovery of a target and their adherence to security best practices, and the severity.

Penetration Test Identify confirmed vulnerabilities in the networks and applications. Are security controls effective? Has the target company’s M&A preparation compromised the organization?

Security Advisory – Inherent risk profiling, targeted risk analysis, compliance quick checks, remediation recommendations for an ongoing security program.

Security Engineering SupportDesign, deploy, and validate new security solutions.

Threat Hunting or Managed Detection and Response (MDR)Monitor and alert on identified threats for the network, applications, endpoints, and web applications in use. Real-time containment and remediation guidance.

Sensitive Data ScanningDetermine type, quantity and use of sensitive information throughout the target organization, and how it is managed and accessed.

Auditing a potential partner for M&A risks is an important prerequisite to proceed with a business combination. And once you complete your M&A, how do you assess what it will take to merge separate organizations and implement one cohesive cyber security program?

This assessment sets the stage for due diligence — the process of finding and mitigating security risks across an organization. Due diligence demonstrates the commitment of a company to keeping customer and confidential data safe, and organizations must be able to clearly identify due diligence efforts in the event of a breach or compromise.

As a result, any mergers and acquisitions cyber security plan must prioritize the creation, implementation, and reliable record keeping of due diligence practices.
