M&A IT Due Diligence Checklist: Key Areas to Review

Amidst continuing geopolitical tensions and economic uncertainties, 85% of CEOs see cybersecurity as their top priority for business growth. At the same time, 65% of executives are concerned about the cybersecurity threats, especially those driven by the growing role of AI. And that’s not surprising, as about 89% of business owners are actively investigating the ways of AI adoption within their organizations. 

It makes it even more challenging to balance cybersecurity approaches and collaboration with partners during such complex financial transactions as mergers and acquisitions (M&A). Luckily, there’s a solution already — IT due diligence (information technology due diligence).

IT due diligence is an assessment of a company’s technology environment during M&A. It implies reviewing IT systems, infrastructure, cybersecurity, software licenses, data management, and digital risks to ensure the company is safe and worth investing in. 

This article focuses on the M&A IT due diligence checklist as the main tool to ensure an effective and thorough IT due diligence.  It also explores how virtual data rooms can help with both the checklist and the whole IT due diligence process.

What Is M&A IT Due Diligence Checklist, and Why Is It Important?

An M&A IT due diligence checklist is practically a roadmap of the areas that need to be reviewed during IT due diligence. It helps buyers and deal teams stay organized and ensure nothing is missed during the investigation. Instead of approaching IT due diligence ad hoc, the checklist sets out clear areas to verify — from infrastructure and contracts to cybersecurity and disaster recovery.

An IT due diligence checklist is crucial because it:

• Ensures all critical IT areas are covered without gaps
• Helps detect potential risks such as compliance issues or data breaches
• Provides a consistent framework for evaluating different target companies
• Speeds up the review by organizing information in a clear format
• Reduces the chance of costly surprises after the deal closes

One of the best ways to grasp the importance of an IT due diligence checklist is to understand the cost of a potential data breach if IT systems are weak and can’t ensure proper cybersecurity measures. The cost of an average data breach in 2025 was $4.4 million. Sounds like a spending business owners would like to avoid.

Pre-Checklist Preparations

Before starting the creation of a technology due diligence checklist, deal teams should take time to set the right foundation. The two main steps here are the following:

• Define the scope. The review must reflect the target company’s industry, scale, regulatory environment, and geography. For instance, a healthcare provider will have different management compliance requirements than a fintech startup. A clear scope helps focus on the most relevant risks, from data security to disaster recovery plans.
  
• Assemble the right experts. IT due diligence requires more than just internal resources. Include technical and security experts, legal advisors, and, when needed, external reviewers who can evaluate the infrastructure deployment model, reporting structure, and management approach to security design. Having diverse expertise reduces the chance of missing sensitive data issues or potential risks.

Key Areas of M&A IT Due Diligence Checklist

Now, let’s take a look at the main areas of review you should add to your IT due diligence checklist and describe what each of them is all about.

Systems, Infrastructure & Architecture Review

The first step in the IT due diligence process is to understand how the target company’s systems are built and whether they can handle future growth. Dedicated M&A deal teams should examine the infrastructure deployment model, applications, and data centers approach to see if they align with the buyer’s business strategy. Weak or outdated architecture often leads to higher costs, limited scalability, and increased potential risks.

The main checklist items to review include:

• Network diagrams and infrastructure deployment model
• Details of cloud and data centers, including resilience and redundancy
• System architecture documentation and integration points
• Current capacity versus future scalability requirements
• Disaster recovery plans and backup strategies
• Performance monitoring tools and operational metrics reports

Vendor and Technology Contracts & Licenses

Vendor agreements and software licenses can create hidden risks if they are not properly reviewed. 

During technical due diligence, deal teams need to check if the target company has valid licenses, clear ownership rights, and deployment independence contractual agreements. Contracts should also be evaluated for renewal terms, hidden costs, or restrictions that may impact business operations after the merger and acquisition process.

Checklist items to review:

• Software licenses, usage rights, and compliance with terms
• Vendor contracts, including renewal dates and costs
• Third-party service agreements for cloud and data centers
• Intellectual property rights and ownership confirmation
• Deployment independence contractual agreements with vendors
• Records of past disputes, escalations, or regulatory inquiries

Security, Privacy & Compliance

Cybersecurity and compliance are often the top concerns in an IT due diligence process. The goal here is to verify how well the target company protects sensitive data and whether it meets management compliance requirements across different jurisdictions. Reviewing policies, past data breaches, and management approach to security design helps buyers assess potential risks and plan for improvements.

Key things to review:

• Information security policies and procedures
• Records of past or current data breaches and incident reports
• Compliance with industry regulations (HIPAA, GDPR, CCPA, etc.)
• Penetration testing results and vulnerability assessments
• Management approach to security design and access controls
• Disaster recovery and business continuity documentation

IT Team, Processes & Competency

Even the best systems fail without the right people to manage them. Reviewing the IT team means looking at the organizational chart, reporting structure, and how processes are run day-to-day. This review assesses whether the team possesses the necessary skills, resources, and clear processes to support continuous improvement, effective release planning, and maintain a customer-focused mindset.

Checklist items to review:

• Organizational chart and reporting structure
• Evaluate IT team skills, certifications, and experience
• Management process delivery trends and escalation rates
• Process documentation for monitoring and troubleshooting
• Team business continuity and succession planning strategies
• Training records and performance reviews

Operational Metrics & Scalability

Finally, buyers should evaluate whether the target company’s technology can grow with the business. This involves checking operational metrics, scalability options, and whether systems support long-term efficiency. A technical due diligence checklist should also cover how the company manages performance monitoring, capacity planning, and continuous improvement release planning.

Checklist items to review:

• System uptime and availability records
• Capacity and scalability reports
• Management process sprint planning documents
• Operational cost breakdowns and efficiency metrics
• Monitoring and reporting tools for key systems
• Plans for future upgrades or migration projects

Sample IT Due Diligence Checklist

Here’s a sample information technology due diligence checklist that you can use and adapt to your specific merger and acquisition process. It covers the main review areas and the type of information or documents that should be collected.

Virtual Data Rooms for IT Due Diligence

Conducting IT due diligence typically involves handling highly sensitive technical documents: from security policies to system architecture diagrams. Sharing this information over email or unprotected platforms can put both parties at risk of data breaches. That’s why most deal teams rely on virtual data rooms to organize and exchange these materials securely. 

VDRs speed up the due diligence process by enabling remote access for authorized users, making it easier for technical, legal, and business teams to work together. Instead of waiting for physical handovers or unsecured file transfers, deal teams can review critical documents in real time, which reduces delays and accelerates the overall merger and acquisition process. 

Here are the main advantages virtual data rooms bring to the IT due diligence process:

• Granular access control. Administrators decide who can view, download, or edit each document, reducing the risk of unauthorized access.
  
• Document watermarking. Every file is automatically marked to discourage leaks and trace responsibility if sensitive data is shared improperly.
  
• Audit trails. Detailed logs track who accessed each file, when, and what actions they performed, helping deal teams maintain compliance.
  
• Version control. Ensures reviewers always see the latest version of a file, avoiding confusion or outdated information.
  
• Secure storage. Documents are encrypted in transit and at rest, protecting them against breaches or accidental loss.
  
• Remote collaboration. Experts from different geographies can access the same repository at the same time without compromising security.
  
• Faster reviews. Centralized storage means technical, legal, and compliance teams no longer waste time on manual document exchange.

Key takeaways

• An M&A IT due diligence checklist helps ensure all technology risks are reviewed before closing a deal.
  
• Preparations for IT due diligence should include defining the scope and involving technical, legal, and security experts.
  
• Key checklist areas cover systems and infrastructure, vendor contracts, security, IT team processes, and scalability.
  
• Virtual data rooms secure sensitive technical information and speed up collaboration across teams during the IT due diligence process.
