Key Steps in Conducting Cyber Due Diligence for SMB Acquisitions

When acquiring a small or medium-sized business (SMB), cyber due diligence requires a methodical approach tailored to the unique challenges SMBs present. These businesses often lack formal IT documentation and structured security practices, making it critical to conduct a thorough evaluation.

Pre-Acquisition Risk Assessment and Initial Review

The first step in cyber due diligence is an initial risk assessment, which lays the groundwork for the entire process. Begin by collecting background details about the target company’s cybersecurity practices. This can be done through questionnaires and publicly available information, focusing on past security incidents, regulatory violations, or compliance issues.

Understand the regulatory requirements relevant to the company’s industry - such as HIPAA for healthcare or PCI-DSS for retail - to identify gaps in compliance. Additionally, request documentation on the company’s IT governance, including who handles cybersecurity decisions and what policies are in place. Many SMBs lack formal IT leadership, which can indicate areas needing closer scrutiny.

This initial phase sets the stage for deeper evaluations, including IT systems, software, and vendor risks.

IT Infrastructure, Asset, and Software Inventory

A detailed assessment of the company’s IT environment is essential. This includes identifying legacy systems, security vulnerabilities, and compliance issues. Evaluating IT assets helps you determine integration feasibility, associated costs, and a roadmap for maintaining business continuity.

Start with hardware and network systems. Document all hardware assets - such as servers, laptops, and networking devices - along with their age, warranty status, and performance history. Cloud services should also be reviewed for cost efficiency and security settings. Since 32% of breaches stem from unpatched systems, it’s critical to examine the maintenance history of these assets.

Next, review the Business Continuity and Disaster Recovery (BCDR) plan. This includes analyzing backup routines, storage locations, and restoration timelines. SMBs often have limited backup strategies, which could pose significant risks to the acquiring company.

Software systems require equal attention. Compile a list of critical applications, their versions, and support availability, noting any end-of-life dates. Also, inventory all Software-as-a-Service (SaaS) subscriptions to understand ongoing costs and assess their security configurations.

Once the technical inventory is complete, move on to a detailed review of cybersecurity measures and compliance protocols.

Cybersecurity Review and Regulatory Compliance Check

Understanding the target company’s cybersecurity policies and incident history is crucial. Request documentation on security policies, access controls, and incident response plans. Assess past breaches and how they were handled to gauge the company’s vulnerability and response readiness.

Evaluate compliance with industry-specific regulations such as HIPAA, PCI-DSS, and CCPA, depending on the company’s sector and customer base. Ask for compliance documentation, audit reports, and any correspondence with regulatory bodies. Non-compliance can lead to hefty fines and legal liabilities that the acquiring company would inherit.

Examine the company’s data protection practices, focusing on how sensitive information is stored, transmitted, and accessed. Verify user access controls to ensure employees only have access to data relevant to their roles, and confirm that access for former employees has been properly revoked.

Vendor and Third-Party Risk Review

Third-party vendors often represent a significant risk during SMB acquisitions. SMBs frequently rely on external providers, which can introduce vulnerabilities, especially if the SMB lacks in-house cybersecurity expertise.

Carefully assess third-party vendors by reviewing their contracts, security practices, and compliance with relevant regulations. Data privacy laws like GDPR, HIPAA, and PCI-DSS extend compliance requirements to these vendors, meaning the acquiring company assumes responsibility for any gaps.

"Third Party Risk Management (TPRM) is a relatively new and complex topic. The scale of the challenge is daunting so companies need to be proactive and strategic in their approach." - Patrick Ryan, Managing Director of Phinity Risk Solutions

Ensure vendor agreements clearly define compliance roles and cybersecurity responsibilities. Review these agreements to identify any weaknesses in security measures or liability provisions that could pose risks to the acquiring company.

Integration and Transition Planning

A well-structured integration plan is essential for maintaining security during the post-acquisition transition. Develop a roadmap for IT integration, data migration, and user access management, including clear communication protocols and staff training plans.

Facilitate collaboration between IT teams from both organizations to ensure quick detection and resolution of any security incidents during the transition. This is particularly important since many breaches occur during mergers and acquisitions when monitoring systems may be disrupted.

Plan for staff training and knowledge transfer to help the acquiring company’s IT team understand the target company’s systems and maintain security standards. This is especially critical if the target company uses unique systems or has specialized security needs.

Establish ongoing monitoring processes to ensure vendor compliance remains intact over time. A proactive approach to Third-Party Risk Management (TPRM) ensures that the safeguards put in place during due diligence continue to protect the organization well beyond the acquisition phase.

Tools and Technologies for Cyber Due Diligence

Once the initial risk assessments are completed, leveraging the right technology tools can significantly enhance the efficiency and precision of cyber due diligence. These tools help identify risks, document findings, and ensure the security of mergers and acquisitions (M&A). Let’s dive into some specific tools that play a key role in this process.
