Technical due diligence gives buyers and investors a clear view of the technology behind a business before they commit capital, finalize an acquisition, or enter a strategic transaction. It helps uncover technology risks that may not be visible in financial statements, such as technical debt, fragile architecture, security vulnerabilities, poor scalability, intellectual property gaps, cloud inefficiencies, and dependence on key engineers.
A structured technical due diligence process goes beyond reviewing source code. It evaluates the company’s architecture, engineering practices, infrastructure, cybersecurity, data privacy, technology roadmap, technical team, and operational readiness, then connects those findings to business and deal impact.
This guide explains the technical due diligence process step by step and provides a practical technical due diligence checklist for buyers and investors. You’ll learn what to review, which evidence to request, the red flags to look for, and how technical findings can affect valuation, deal terms, integration planning, and post-acquisition priorities.
What is Technical Due Diligence?
Technical due diligence (Tech DD) is an independent assessment of a company’s technology, software, infrastructure, engineering practices, security, data, intellectual property and technical team to identify risks that could affect an investment, acquisition or other major transaction.
The assessment typically covers the company’s software architecture, technology infrastructure, cybersecurity, data environment, engineering processes, technical debt, third-party dependencies, intellectual property, technology costs, scalability and engineering team. The goal is not simply to identify technical issues, but to understand how those issues could affect the company’s performance, growth and investment outlook.
Technical due diligence is usually performed by independent technology specialists, technical consultants or experienced engineering teams who can evaluate the technology beyond what is visible in management presentations or standard financial due diligence.
The findings are primarily used by private equity firms, corporate development teams, strategic acquirers, investment committees and company leadership. Depending on the transaction, Tech DD may take place during initial deal screening, before closing, during deal structuring, or after an acquisition as part of post-close planning and value creation.
Ultimately, Tech DD helps decision-makers determine whether technology represents a material risk, requires additional investment, creates integration challenges, or provides opportunities for growth and value creation.
Technical Due Diligence answers 3 Questions:
1. What technology risks exist?
Identify weaknesses, dependencies, technical debt, security gaps and other issues.
2. How serious are those risks?
Assess their potential impact on the business, investment thesis and future growth.
3. What will it cost and take to remediate them?
Estimate the investment, resources and timeline required to address material issues.
This moves technical due diligence beyond a generic checklist toward a more decision-oriented process: evidence → risk → cost → deal decision.
The 7-Phase Technical Due Diligence Process
A technical due diligence process should move from understanding the transaction and gathering evidence to assessing technical risk, estimating remediation requirements, and determining the implications for the deal. A practical approach is to structure the assessment into seven phases.
Phase 1: Scope & Discovery
The first phase establishes what the diligence needs to answer. The scope should be aligned with the transaction type, investment thesis and business model, rather than applying the same technical checklist to every company.
The diligence team defines the technology systems and products in scope, identifies business-critical dependencies, establishes the key questions to investigate, and identifies the relevant stakeholders. The team also agrees on the timeline, evidence required, and areas that require deeper technical investigation.
A typical Information Request List (IRL) may include:
- System and architecture diagrams
- Application and technology stack details
- Infrastructure and cloud documentation
- Source-code repositories
- CI/CD and development process documentation
- Security and compliance reports
- Technology contracts and vendor dependencies
- Product and engineering roadmaps
- Technology organization and team structure
- Recent incidents, outages and remediation records
The output of this phase is a clear diligence scope and evidence plan.
Phase 2: Technology Architecture Assessment
The technology architecture assessment examines how the company’s software systems are designed, connected and expected to perform as the business grows. This is where technical due diligence architecture goes beyond simply listing infrastructure components.
The assessment typically covers the application architecture, technology stack, databases, APIs, integrations, system dependencies and architecture documentation. The diligence team evaluates whether systems are scalable and reliable, identifies single points of failure, and looks for architectural constraints that could limit growth or create significant modernization requirements.
The key question is not whether the company uses a particular technology, but whether its current architecture can reliably support the business requirements assumed in the transaction.
Phase 3: Engineering & Codebase Assessment
The engineering assessment looks at the quality and sustainability of the codebase and the practices used to develop and maintain it.
This includes code quality, maintainability, technical debt, test coverage, version control, CI/CD, release processes, dependency management and development methodology. The assessment can also review open-source components, technical documentation, engineering velocity and areas where knowledge is concentrated in a small number of individuals.
For a buyer, these factors help determine whether the engineering organization can maintain the existing product and deliver the roadmap without requiring disproportionate investment or creating execution risk.
Phase 4: Infrastructure, Cloud & Operations Assessment
Infrastructure, cloud and operations are assessed together because they directly affect the company’s reliability, scalability and technology operating costs.
The review may cover AWS, Azure or Google Cloud environments, cloud architecture, infrastructure as code, development and production environments, observability, monitoring, backups, disaster recovery, business continuity and redundancy.
The diligence team also examines cloud spending and operational dependencies to determine whether the current environment can support projected growth at a sustainable cost. Reliability is considered from a buyer’s perspective: significant downtime, weak recovery capabilities or excessive dependence on individual systems can translate into operational and financial risk.
Phase 5: Security, Data Privacy & Compliance Assessment
Security, privacy and compliance are closely connected in a transaction because weaknesses in any of these areas can create financial, operational or regulatory exposure.
Cybersecurity
The assessment reviews areas such as known vulnerabilities, penetration testing, access controls, MFA, secrets management, incident history and incident response capabilities. The objective is to determine whether material security weaknesses could affect the transaction or the company’s future operations.
Data Privacy
The team evaluates how personal and sensitive data is collected, processed, stored and protected, including requirements under regulations such as GDPR, CCPA and the DPDP Act. Data residency, encryption and retention practices may also be reviewed where relevant.
Compliance
Relevant certifications and regulatory requirements may include SOC 2, ISO 27001 and industry-specific requirements. The assessment can also consider audit history, outstanding compliance issues and potential regulatory exposure.
Phase 6: Product, Scalability & Technology Roadmap
This phase connects the technical assessment directly to the company’s future plans. The question is not simply whether the current product works, but whether its technology can support the growth assumptions behind the investment thesis.
The review considers product architecture, scalability, product-market requirements, roadmap feasibility, engineering capacity, technical constraints, upcoming platform changes and technical dependencies. It also examines whether additional infrastructure or engineering investment will be required to support projected growth.
For example, if the investment thesis assumes rapid international expansion, the diligence should consider whether the architecture, infrastructure, data model and engineering organization can support that expansion.
Phase 7: Risk Analysis & Technical Due Diligence Report
The final phase turns technical findings into an investment-oriented assessment. Instead of simply documenting issues, each material finding should explain what it means for the business and what should happen next.
A useful structure is:
- Finding: What was discovered?
- Severity: Is the issue Critical, High, Medium or Low?
- Business impact: What could happen if it remains unresolved?
- Remediation: What needs to change?
- Cost: What resources or investment will remediation require?
- Timeline: How long is remediation expected to take?
- Deal implication: Could it affect valuation, deal terms, closing, integration or the post-close roadmap?
The final technical due diligence report should therefore connect technical evidence to business consequences and recommended actions. This gives investors a clearer basis for deciding whether a risk should affect the transaction, be addressed through deal terms, or become a post-close remediation or value-creation priority.
In practice, the process should lead from evidence → risk → business impact → remediation cost and timeline → deal decision.
Technical Due Diligence Checklist for Buyers
A technical due diligence checklist is most useful when it helps buyers move from what should be reviewed to what evidence supports the assessment and what the findings could mean for the transaction. Rather than simply checking whether a company has a documented architecture or security policy, buyers should validate those claims against technical and operational evidence.
| Area | What to Review | Evidence to Request | Red Flags | Deal Impact |
|---|---|---|---|---|
| Architecture | Scalability, dependencies, APIs, integrations, system design | Architecture diagrams, ADRs, system documentation | Undocumented dependencies, tightly coupled systems, single points of failure | Integration risk, scalability constraints |
| Codebase | Code quality, maintainability, testing, technical debt | Repository access, code samples, CI/CD configuration, test reports | High technical debt, poor test coverage, outdated dependencies | Remediation cost, engineering risk |
| Infrastructure | Cloud architecture, reliability, environments, disaster recovery | Cloud architecture, infrastructure documentation, cloud bills, DR plans | Single-region dependency, weak recovery capabilities, excessive infrastructure costs | Operational risk, additional investment |
| Security | Vulnerabilities, access controls, authentication, incident response | Penetration tests, vulnerability reports, security policies, incident logs | Critical vulnerabilities, excessive privileges, unresolved incidents | Security risk, potential closing conditions |
| IP | Technology ownership, licensing, third-party and open-source usage | IP assignments, licensing agreements, OSS inventory | Disputed ownership, restrictive licenses, missing assignments | Legal and valuation risk |
| Data | Data architecture, privacy, residency, protection and retention | Data maps, privacy policies, processing records, security controls | Regulatory exposure, unclear data ownership, inadequate controls | Compliance risk, remediation requirements |
| Team | Engineering skills, ownership, organization, key-person dependency | Engineering org chart, ownership map, role descriptions, hiring plans | Critical knowledge concentrated in individuals, capability gaps | Continuity risk, hiring costs |
| Product | Product architecture, roadmap, scalability and technical constraints | Product roadmap, architecture documentation, capacity plans | Growth bottlenecks, technically infeasible roadmap items | Investment thesis risk, additional technology investment |
The checklist should be used as a starting point for investigation rather than a pass/fail exercise. Evidence should support the assessment, particularly for issues that could influence valuation, deal terms, integration planning or post-close investment.
For example, identifying “high technical debt” is only the beginning. The diligence should establish where the debt exists, how it affects the product, what remediation requires, and whether the associated cost or timeline changes the investment decision. This is what turns a technical checklist into a transaction-focused due diligence framework.
Here you can learn more in details by Dextra Labs’ Technical Due Diligence checklist for buyers:
1. Technology Infrastructure
A solid technology foundation is critical for any business to operate efficiently and scale effectively.
- Hardware: Are the servers, networking equipment, and storage solutions contemporary and sufficient to sustain operations? Aging hardware can create performance bottlenecks and increase maintenance costs.
- Software Systems: Which databases, enterprise apps, and operating systems are in use? Look for compatibility and modernization options.
- Scalability and Reliability: Does the infrastructure have the capacity to handle growth? If demand spikes tomorrow, will it hold up or crash under pressure?
2. Intellectual Property
The security of your investment depends on the IP supporting it. Verify that everything is secure and authentic.

- Assessment: Are there parts of the system built with shortcuts that now require significant effort to fix?
- Impact: How does this debt affect the company’s ability to scale or introduce new features?
- Resolution Plans: Does the company have a roadmap for reducing technical debt and modernizing systems?
9. Infrastructure and Cloud Strategy
Cloud-based systems are standard for many companies, but they still need to be efficient and cost-effective.
- Cloud Utilization: Which cloud providers are used (AWS, Azure, GCP)? Are the services optimally configured?
- Cost Optimization: Is the company managing cloud expenses effectively, or are there inefficiencies?
- Redundancy: What happens if a data center goes down? Look for strong backup and failover systems.

Who Performs Technical Due Diligence?
Technical due diligence can be performed by different technology professionals depending on the size, complexity and nature of the transaction. Common options include:
- CTO: An experienced CTO can assess technology strategy, architecture, engineering capabilities and technical risks, particularly in smaller or less complex transactions.
- Technical Due Diligence Consultant: A specialist consultant evaluates the technology environment specifically in the context of an investment or acquisition, with a focus on identifying material risks and required remediation.
- Engineering Leadership: Engineering leaders can assess the codebase, development practices, architecture and technical team, especially when they have sufficient technical depth and transaction context.
- Independent Technical Advisor: An external technical advisor provides an objective assessment of the target’s technology without being responsible for its day-to-day technology decisions.
- Specialist Tech DD Firm: Specialist firms bring dedicated technical due diligence expertise and can typically assess architecture, engineering, infrastructure, cybersecurity, data, costs and scalability as part of a structured transaction review.
Technical Due Diligence Information Request List:
A technical due diligence information request list defines the documents and evidence a buyer or diligence team needs from the target company. It is typically shared during the initial discovery phase and can also form part of the technical due diligence data room.
The exact request varies by transaction, but a typical list includes:
| Category | Documents / Evidence |
|---|---|
| Architecture | Architecture diagrams, ADRs, system inventory, dependency documentation |
| Code | Repository access, commit history, codebase documentation |
| Engineering | SDLC documentation, CI/CD configuration, release process, development methodology |
| Security | Penetration-testing reports, vulnerability assessments, security policies, incident records |
| Cloud | Cloud architecture, billing records, utilization data, infrastructure documentation |
| Data | Data maps, data-flow documentation, privacy policies, retention policies |
| IP | IP assignments, licensing agreements, open-source software inventory |
| Team | Engineering organization chart, roles, responsibilities, ownership information |
| Product | Product roadmap, technical requirements, product architecture documentation |
| Operations | Uptime records, monitoring information, incident history, backup and disaster recovery plans |
This information request list can also be used to structure a technical due diligence questionnaire, with questions tailored to the target’s technology environment. For example, the diligence team may ask who owns critical systems, how deployments are managed, what happens during a major outage, or whether third-party dependencies create material operational or licensing risks.
The objective is not to collect documents for their own sake. The requested evidence should allow the diligence team to validate the target’s technology claims, identify material risks, estimate remediation requirements, and determine their potential impact on the transaction.
How Long Does Technical Due Diligence Take?
The time required for technical due diligence depends on the scope of the assessment, complexity of the technology environment, availability of technical evidence, and access to the target’s team and systems. A focused review may be completed relatively quickly, while a complex transaction involving multiple products, infrastructure environments or integrations requires a deeper assessment.
| Engagement | Typical Scope |
|---|---|
| Rapid DD | Focused risk screening of the most material technology areas |
| Standard DD | Broader assessment of architecture, engineering, infrastructure, security and technology operations |
| Complex DD | Detailed review involving multiple products, systems, integrations or technology environments |
| Enterprise / PE | Deep assessment of architecture, security, infrastructure, engineering, scalability, costs and integration considerations |
In practice, technical due diligence can range from a few days to several weeks, but the timeline should be established based on the specific transaction rather than treated as a fixed duration. Delays in providing documentation, system access or stakeholder availability can also extend the engagement.
For buyers, the priority should be sufficient depth to identify material technology risks without slowing the transaction unnecessarily. The right scope and evidence plan are therefore often more important than setting an arbitrary number of days.
How Much Does Technical Due Diligence Cost?
Technical due diligence costs vary based on the size of the technology estate, number of repositories and systems, security and compliance scope, deal complexity, and turnaround requirements.
A focused review of a smaller technology environment will generally require less effort than a complex transaction involving multiple products, cloud environments, integrations, and regulatory requirements.
For detailed pricing factors and cost ranges, see our [Technical Due Diligence Cost guide].
What Does a Technical Due Diligence Report Include?
A technical due diligence report brings together the evidence gathered during the assessment, the technical findings, their business impact, and the actions required to address material risks. For buyers, the report should make it clear what was reviewed, what was found, how significant the issues are, and what they mean for the transaction.
A buyer-ready technical due diligence report typically includes:
- Executive Summary: Key findings, material risks, overall technology assessment and the issues that require immediate attention.
- Scope & Methodology: What was reviewed, the evidence examined, stakeholders interviewed, and the approach used for the assessment.
- Technology Architecture: Application architecture, technology stack, integrations, dependencies, scalability and architectural constraints.
- Engineering & Codebase: Code quality, development practices, testing, CI/CD, technical debt and engineering processes.
- Infrastructure & Cloud: Cloud architecture, reliability, environments, monitoring, disaster recovery, redundancy and infrastructure costs.
- Security: Cybersecurity controls, vulnerabilities, access management, security testing and incident history.
- Data & Privacy: Data architecture, privacy practices, data protection, residency, retention and relevant regulatory requirements.
- IP & Licensing: Technology ownership, intellectual property assignments, third-party licenses and open-source software usage.
- Product & Scalability: Product architecture, roadmap feasibility, scalability and the technology’s ability to support projected growth.
- Team & Engineering Organization: Team structure, technical capabilities, ownership, capacity and key-person dependencies.
- Technical Debt: Significant legacy systems, deferred engineering work, outdated components and the potential effort required to address them.
- Risk Matrix: Prioritized findings categorized by severity, business impact and urgency.
- Remediation Recommendations: Recommended actions, estimated effort, dependencies and priorities for addressing material issues.
- Deal Implications: How significant findings could affect valuation, deal terms, closing conditions, integration or required investment.
- Post-Close Priorities: The most important technology initiatives to address after the transaction, including remediation, modernization, security improvements and value-creation opportunities.
The strongest reports do more than document technical problems. They connect evidence → finding → risk → remediation → deal implication, giving investors a practical basis for making transaction and post-close decisions.

Technical Due Diligence Red Flags Buyers Should Watch For
Technical issues are not automatically deal breakers. The concern is whether a weakness creates material business risk, unexpected remediation costs, scalability constraints, or a problem for the investment thesis.
During technical due diligence, buyers should pay particular attention to red flags such as:
- Undocumented architecture: Critical systems, dependencies or data flows are poorly documented, making the technology difficult to understand or maintain.
- Critical single points of failure: A single system, service or component can cause significant disruption if it fails.
- High technical debt: Accumulated legacy code and deferred engineering work could require substantial investment after acquisition.
- Low test coverage: Limited automated testing increases the risk of defects and makes future changes harder to deliver safely.
- Unsupported technologies: Applications depend on obsolete frameworks, libraries or platforms that may no longer receive security or vendor support.
- Critical security vulnerabilities: Significant vulnerabilities or unresolved security findings could expose the business to operational, financial or reputational risk.
- Missing IP assignments: Key technology may not have clear ownership or appropriate intellectual property assignments from employees, contractors or third parties.
- Open-source licensing risk: Untracked or improperly licensed open-source components may create legal or distribution restrictions.
- Key-person dependency: Critical technical knowledge is concentrated among a small number of engineers, creating continuity and execution risk.
- Undocumented cloud infrastructure: Important infrastructure is poorly documented or dependent on manual processes that are difficult to reproduce.
- Unsustainable cloud costs: Infrastructure spending grows disproportionately with usage or lacks sufficient cost controls and visibility.
- Weak disaster recovery: Backup, recovery or business continuity capabilities may be inadequate for business-critical systems.
- Missing observability: Limited logging, monitoring or alerting makes it difficult to detect problems and determine their root cause.
- Unrealistic engineering capacity: The product roadmap depends on more engineering capacity than the company currently has or can realistically add.
- Unresolved compliance issues: Outstanding regulatory, audit or compliance gaps could create financial or operational exposure.
The significance of a red flag depends on the severity, business impact, likelihood, remediation cost and timing. A legacy component that can be replaced through a planned modernization project may be manageable; a critical security vulnerability or unresolved IP ownership issue may require much more immediate attention.
For a deeper breakdown of the issues buyers should investigate, see our Technical Due Diligence Red Flags guide.
Technical Due Diligence vs Technical Audit
Technical due diligence and a technical audit both examine a company’s technology, but they serve different purposes. Technical due diligence is primarily transaction-focused, while a technical audit is generally performed to evaluate and improve technology during ongoing operations.
| Technical Due Diligence | Technical Audit | |
|---|---|---|
| Primary purpose | Support a transaction or investment decision | Evaluate technology health and identify improvements |
| Timing | Typically before an acquisition or investment | During ongoing operations |
| Who uses it | Investors, PE firms and acquirers | Company leadership, CTO and technology teams |
| Focus | Deal risk, scalability, remediation and investment implications | Technology quality, operational issues and improvement opportunities |
| Output | Risk assessment and deal recommendations | Audit findings and improvement recommendations |
The distinction is important because the same technical issue can have different significance depending on the context. A technical debt problem, for example, may be evaluated primarily for its remediation cost and impact on an acquisition during Tech DD, while a technical audit may focus more on how that debt affects day-to-day engineering performance.
For a broader assessment focused on the health and improvement of an existing technology environment, see our Technical Audit guide.
