What Is Technology Due Diligence?

A comprehensive guide to evaluating technology assets, risks, and opportunities during mergers and acquisitions.

Definition of Technology Due Diligence

Technology due diligence is the systematic evaluation of a company's technology stack, software architecture, cybersecurity posture, engineering team, and development practices during a merger, acquisition, or investment.

Unlike financial or legal due diligence, technology due diligence focuses on the quality, scalability, and risk profile of the target's technical assets and capabilities.

Why Technology Due Diligence Matters in M&A

In modern transactions, technology is often the most valuable — and most misunderstood — asset. Poor technology diligence has led to overpayments, failed integrations, and post-close surprises.

A rigorous technology assessment helps acquirers understand hidden risks, validate growth assumptions, and plan integration with confidence.

  • Identify technical debt that could delay product roadmaps
  • Assess scalability of infrastructure and architecture
  • Evaluate cybersecurity vulnerabilities before close
  • Understand engineering team strength and retention risk

Key Areas Covered

A thorough technology due diligence engagement typically covers the following domains:

  • Software architecture and code quality
  • Infrastructure and cloud operations
  • Cybersecurity and data privacy
  • Engineering organisation and processes
  • Intellectual property and licensing
  • Product roadmap viability

When to Conduct Technology Due Diligence

Technology due diligence is most commonly performed during the exclusivity period of an acquisition, but increasingly buyers initiate preliminary assessments during the indication of interest (IOI) stage.

Early-stage assessments allow deal teams to flag critical risks before significant resources are committed.

Frequently Asked Questions

What is the difference between technology due diligence and IT due diligence?
Technology due diligence evaluates the strategic and engineering aspects of a company's technology — architecture, code quality, scalability, and security. IT due diligence focuses on operational infrastructure such as networks, hardware, and IT service management.
How long does technology due diligence take?
A typical technology due diligence engagement takes 2 to 4 weeks, depending on the complexity of the target and the depth of access provided; however, Diligenze is generally able to complete the engagement within 72 hours of receiving the final documentation or outstanding questions.
Who performs technology due diligence?
Technology due diligence is usually performed by specialised advisory firms with deep expertise in software engineering, cybersecurity, and cloud infrastructure — often working alongside the buyer's deal team.

What does a SOC 2 report actually tell a buyer?

A SOC 2 tells you whether controls for a defined system were suitably designed and, for a Type II, operated effectively over a period. That is useful assurance for a specific purpose. Technology due diligence asks a broader set of questions.

What technology problems actually reprice a deal?

Most technology problems found in diligence go on a post-close to-do list. A small number change the price or the structure of the deal. Here's which ones, and why they behave differently.
