IT Due Diligence: Avoid Common Pitfalls + The Ultimate Checklist

Last Updated on April 16, 2025

Have you ever been buried in technical documentation while executing a merger, and wondered if that one thing that would make or break the deal might fall through the cracks? Or if you’re a Private Equity professional, you’ve seen one too many deals blow up over IT integration issues. You are not alone.

In the past year, most everyone has learned the hard way that old-school IT due diligence is no longer good enough. When the technology stack of your target is going to drive a significant portion of your investment, you need more than a checklist.

The potential cost? Very high. From closets full of legacy servers to compliance issues that don’t surface until months after closing, poor technical due diligence can end up costing your deal big time. That’s why proper due diligence is so important – it’s the difference between uncovering potential landmines, inefficiencies, and value drivers hidden within a company’s technology stack.

But here’s the good news – you don’t have to learn these lessons the hard way, watching millions in value walk out the door.

This guide takes the mystery out of technical due diligence, tells you exactly what NOT to do and provides a comprehensive checklist so you know you’re asking the right questions at the right time. No theory, no consultant-speak – just practical insight that will protect your investments and help you create value.

The Importance of Technical Due Diligence

Technical due diligence isn’t a checkbox — it’s a comprehensive review of a target company’s technology. It’s a deep dive into the servers, software, data security, disaster recovery, and more. Technical due diligence is a specialized review that helps acquiring companies identify potential technical issues, assess the target company’s technical capabilities, and determine the appropriate purchase price. By peeling back the layers of the technical components, the acquiring company can be sure that the target company’s technology aligns with the company’s strategic objectives and growth initiatives while also minimizing risk and maximizing the deal value.

How NOT to do an IT Due Diligence: 

1. Relying on High-Level Metrics Alone

Have you ever looked at a company’s financial statements without seeing how it is actually running? I’m sure you have, and the result was a failed deal. If you don’t spend time to understand the technical reality of a company’s business, then you’re relying on charts and executive summaries. You’re essentially buying a house without an inspection and will be surprised when the first rain comes.

Don’t skip hiring technical experts in favor of skimming executive reports – this mistake can cost you millions when systems crash and can’t scale after you’ve signed the papers.

2. Confusing Compliance with Capability

Think a SOC 2 certification means their systems are rock-solid? Think again. Assuming regulatory compliance equals operational readiness is a rookie mistake that’ll bite you later. Those fancy certifications like GDPR or ISO 27001 just mean they followed the rules – not that their tech can handle what you need tomorrow.

3.  Skipping Independent Verification

If you saw a used car salesman say “no need for a mechanic – I just looked it over,” wouldn’t you run the other way? Of course you would. But that’s exactly what companies do by accepting a target’s word about their environment. And if you let your security strategy rely on internal assessments, you’re bound to miss legacy infrastructure, integrations gone wrong, and potential security risks that could cripple your business.

4. Prioritizing Speed Over Thoroughness

Are you rushing your technology diligence to meet a close-by deadline? If so, you may as well light your money on fire. Your rushed process won’t uncover integration challenges, outdated technology, and data security risks that will cost you dearly down the line. Even when the clock is ticking, your due diligence checklist needs to identify risks that could impede operations and growth plans.

5. Ignoring Future-Readiness

Just because it works today doesn’t mean it will work tomorrow. We recently worked with a manufacturing client who was set to acquire another large manufacturer. During due diligence, the target company’s ERP system worked flawlessly, but turned out to be completely incompatible with their future-state needs. The result? $7.2M in un-budgeted implementation costs and 18 months of operational disruption that an in-depth future-state review would have avoided.

6. Don’t Underestimate Modern Infrastructure Complexity

You don’t count servers in a closet anymore. You need to consider cloud, microservices, and hybrid architectures. Legacy due diligence misses cloud security issues. Legacy due diligence misses API integration issues. Legacy due diligence misses data governance issues hiding in plain sight.

A comprehensive understanding of the target company’s infrastructure helps prevent future growth limitations and business continuity risks. Through proper due diligence, organizations can better assess outdated infrastructure, evaluate sensitive data handling, and align findings with strategic goals. This modern approach to IT due diligence checklist helps ensure successful acquisitions while minimizing potential integration challenges.

Common Mistakes to Avoid

There are several common mistakes that acquiring companies make during the due diligence process. These include:

• There are several common mistakes acquirers make during tech due diligence. These include:
• Failing to conduct thorough technical diligence, resulting in a lack of visibility into risk until closing
• Missing potential technical landminines that are detonated as unexpected costs after closing
• Failing to adequately assess the target company’s technical capabilities, leading to integration challenges
• Misjudging the true value of the acquisition, resulting in overpayment or missed value

The best way to avoid these traps is to complete a thorough and detailed technical due diligence process. Make sure you find and address all potential risks before closing the deal.

The Ultimate IT Due Diligence Checklist

Phase 1: Infrastructure and Operations

Have you ever seen the back-end of a hybrid IT environment? Your due diligence process should always begin with an assessment of the infrastructure, including both cloud-based and on-premise systems. This is especially important in technology companies where the infrastructure is the lifeblood.

Your evaluation should compare what exists today to what will be needed tomorrow. Some of the key areas to consider include:

Data Center Operations:

• Primary and secondary data centers
• Redundancy and failover
• Power and cooling maturity
• Physical security and access controls

Your evaluation framework should consider both the current state and your future growth:

Development and Integration Capabilities

As you evaluate the technical underpinnings of a company, you should consider both software development and how systems are integrated. This means evaluating their development environment, code pipeline, version control, and testing frameworks. You should also evaluate their API documentation, service architecture, integration patterns, and third-party dependencies.

Phase 2: Security and Compliance

Security assessment isn’t a one-and-done thing – it requires looking at both technical defenses and operational procedures:

Cybersecurity Framework Implementation:

1. Threat detection and response capabilities
2. Network security architecture
3. Endpoint protection measures
4. Security monitoring and logging

Consider this security maturity assessment framework:

Domain	Basic	Advanced	Enterprise-Grade
Access Control	Password policies	MFA implementation	Zero trust model
Network Security	Basic firewall	IDS/IPS systems	Advanced threat protection
Data Protection	Encryption at rest	DLP systems	Comprehensive encryption framework

Compliance and Governance Assessment

Regulatory compliance is more complex than you think. A best-in-class data privacy framework requires a thorough impact assessment, a clear data classification scheme, cross-border transfer processes, and a robust privacy policy.

Meanwhile, protecting your intellectual property means making sure you own the source code, analyzing patents in detail, tracking open source compliance, reviewing IP rights and licensing agreements, and more.

All these parts have to work together to ensure full compliance and protect valuable tech assets. And don’t forget – a technology due diligence checklist is a must-have for transactions to evaluate tech assets and mitigate risk.

Modern IT due diligence must also contend with wildly different international requirements that affect tech infrastructure and the value of a deal. From Europe’s GDPR to Asia’s data sovereignty laws, regional requirements can directly influence technology architecture decisions.

Region	Key Regulations	Technical Requirements	Deal Impact
European Union	GDPR, NIS2	Data localization, Processing controls	Infrastructure modification costs
North America	CCPA, HIPAA, SOX	State-specific systems	Multi-jurisdiction compliance expense
Asia-Pacific	PIPL, PDPA	Local processing requirements	Regional infrastructure investment

Phase 3: Strategic Value Assessment

Flipped over to see what’s really driving innovation at your target company? Assessing digital maturity and innovation potential means looking at multiple dimensions. The innovation pipeline analysis should examine current R&D projects, check how well the tech roadmap supports business goals, review innovation governance structures, and assess the strength of the patent portfolio. 

Measuring readiness to transform digitally involves evaluating the organization’s alignment with a strategic vision, the extent of transformation, the organization’s ability to manage change, and the quality of digital talent.

This holistic assessment is crucial to understanding the organization’s ability to scale and evolve over time.

Performance and Scalability Analysis

When measuring performance and scalability, your due diligence will need to consider the system’s performance against industry benchmarks. This will include metrics such as transaction processing speed, system response time, resource utilization and patterns, and peak load.

The growth readiness assessment should encompass a comprehensive review of scalability architecture, coupled with a robust capacity planning methodology. This assessment must also evaluate performance optimization potential while carefully considering how existing technical debt might impact future growth trajectories. 

These factors, combined, help to assess if the system is able to handle the current workload and meet the business goals for the future.

Phase 4: Integration Planning

A good integration strategy starts with an in-depth compatibility analysis that considers many aspects of the two systems that are being integrated. An integration compatibility analysis should include a comparison of the technology stack to ensure that the different systems are able to communicate with one another. It should also evaluate the data model compatibility, as different data models can make integration a nightmare. Finally, an integration architecture analysis is necessary to understand how the integration will affect the current technical debt.

How complex will your integration be? The answer depends on three key considerations:

• Data Migration: Typically high complexity with high risk. Often requires careful team sizing and timeline planning.
• System Integration: The level of complexity depends on the technical expertise required and the existing architecture
• Process Alignment: Complexity also depends on the change management requirements and organization readiness

By understanding these differences, you can better plan the right resources and timeline to ensure your integration is a success.

Value Realization Planning

Value realization planning in IT due diligence enables mapping of technical capabilities to value creation opportunities. Some key synergies include technology consolidation, operational efficiency, innovation acceleration, and cost savings. Comprehensive risk mitigation requires technical risk assessment, mitigation planning, resource allocation, and a timeline to facilitate successful integration and business continuity.
