A Guide to Successful Internal Investigations

Internal investigations are crucial for uncovering and addressing wrongdoing in large organizations. Whether dealing with misconduct, fraud, regulatory violations, or data breaches, a well-executed investigation protects your company, employees, and reputation.

With the rise of digital data and complex workplaces, traditional investigative methods are no longer enough. Technology now plays a vital role in streamlining processes, reducing costs, and ensuring defensibility.

For enterprises and law firms managing compliance, data, and risk, adopting a tech-driven approach is essential. Hanzo’s solutions enhance efficiency and accuracy throughout the process, making investigations more effective. This guide outlines key steps in a successful investigation process and how modern technology can support them.

What Is an Internal Investigation?

An internal investigation is an inquiry carried out by an organization to examine allegations of misconduct, legal violations, or policy breaches. This type of investigation aims to determine whether someone violated the company’s policies, laws, or regulations, and if so, identify the responsible parties and clarify the situation. Successful internal investigations also ensure accountability, protect the organization’s integrity, and prevent future misconduct while offering corrective measures or recommendations for improvement based on the findings.

A variety of factors can trigger an investigation, including:

  • Reports from whistleblowers
  • External audits or investigations
  • Allegations of misconduct
  • Regulatory inquiries
  • Media reports or lawsuits

The goal of these investigations is to either confirm or dispel any alleged wrongdoing. If the investigation confirms misconduct, the company must take appropriate corrective actions to mitigate any potential damage to its operations, reputation, or legal standing.

What Triggers an Internal Investigation?

Internal investigations help large organizations, especially those with thousands of employees or multiple branches, comply with laws and regulations. They are also a mechanism for quickly addressing any issues that could harm the company’s integrity or brand.

Some common examples of misconduct that may require this procedure include:

  • Workplace policy violations: Employees not adhering to company policies, including code of conduct and anti-discrimination rules
  • Fraud: Misuse of company resources, financial misconduct, or accounting irregularities
  • Intellectual property theft: Employees stealing or misusing proprietary company data or products
  • Regulatory violations: Non-compliance with industry-specific regulations (e.g., Financial Industry Regulatory Authority, Securities and Exchange Commission, General Data Protection Regulation)

As your enterprise grows, so does the complexity of successfully managing internal inquiries. Investigating potential misconduct can become overwhelming without the right tools, especially if you are dealing with collaboration across teams or a large volume of communications and data.

The Key Steps in Conducting an Internal Investigation

While every investigation is unique, most in-house investigations follow a similar process. Here are some of the key steps involved:

Planning the Investigation

A successful internal investigation begins with thorough planning. It is important to determine the purpose and scope of the investigation before you start. Planning should include:

  • Defining the objective: Understand the core reason for the investigation (e.g., to confirm a policy violation or clarify a legal breach)
  • Identifying key questions: Determine exactly what needs investigating
  • Establishing the timeline: Set realistic timeframes for completing each phase of the investigation
  • Choosing the right investigators: This could be your internal team, in-house legal counsel, or third-party experts

The planning stage ensures you approach the investigation clearly and intentionally, preventing unnecessary delays and confusion.

Selecting the Investigation Team

The right team is essential when conducting internal due diligence. Depending on the investigation’s scope and nature, in-house teams such as human resources, security, or legal counsel may handle it, or you may hire external experts for a more impartial review.

  • Internal HR teams: HR professionals are often the first point of contact for employee-related investigations and are well-versed in company policies and employee relations
  • Internal legal or compliance teams: In-house legal or compliance departments can handle investigations requiring legal expertise, especially for regulatory violations
  • External consultants: External experts, such as law firms or private investigators, may be necessary to ensure impartiality in highly sensitive or complex investigations

Each team has specific strengths, and understanding each team’s unique advantages and challenges will help you determine which is best for your particular circumstances.

Data Preservation, Collection, and Review with Hanzo’s Suite of Products

One of the most crucial aspects of internal investigations is gathering and preserving relevant evidence. Technology can make a significant difference in this area. Traditional data collection methods are no longer sufficient due to the increasing use of digital tools and communication platforms such as Slack, Google Drive, and Microsoft Teams.

Hanzo’s suite of products empowers enterprise teams to efficiently manage, analyze, and act on complex data across collaboration platforms, email systems, and social media channels. Whether for eDiscovery, compliance, or internal investigations, Hanzo provides powerful tools to preserve, map, and review data with precision and ease.

  • Preserve and capture data: Hanzo’s tools automatically collect and defensibly preserve digital communications from collaboration platforms such as Slack, Microsoft Teams, Google Workspace, Jira/Confluence, Asana, and other SaaS applications. Illuminate ensures that all data is captured in context—including attachments, emoji, and metadata—so teams can reconstruct conversations accurately and defensibly.
  • AI-powered review: Spotlight AI accelerates internal investigations and data discovery by automatically identifying and guiding users to the most relevant content hidden within vast volumes of complex data. Traditional search methods rely on rigid keyword-based queries, often missing crucial context. Spotlight AI goes beyond this by understanding the inherent meaning and relationships within data, surfacing hidden patterns and connections. This ensures that teams don’t just find data—they understand why it’s relevant, with transparent explanations that clarify decision-making. The result? Faster insights, lower costs, and reduced risk.
  • Data mapping and collection: Illuminate allows teams to collect exactly what they need and nothing more, streamlining audits and early case assessments. Instead of sifting through excessive, irrelevant data, Illuminate builds a comprehensive and structured map of an organization’s digital footprint, helping legal and compliance teams home in on critical information quickly and defensibly.

Spotlight AI and Illuminate integrate seamlessly with existing workflows, whether leveraging keywords, date filters, or channel-based culling. These tools also work in tandem with external legal teams and service providers, offering flexible solutions that reduce data volumes while preserving essential insights.

By combining automation, AI-driven insights, and targeted data collection, Hanzo empowers legal, compliance, and investigative teams to work smarter, faster, and more cost-effectively—so they can focus on strategy, not manual data review.

Your team can significantly reduce the time spent manually reviewing documents by utilizing automated tools to collect and analyze data. These tools ensure that nothing important is overlooked.

Conducting Interviews

Interviews with key individuals are often essential to internal investigations. Depending on the nature of the alleged misconduct, you may need to interview employees, witnesses, or even the individuals under investigation.

It is important to document each interview thoroughly and ensure that all participants understand the confidential nature of the investigation. In some cases, legal counsel should be present to ensure the integrity of the process.

Creating the Investigation Report

Once you have completed the in-house investigation, you must document the findings in a clear and concise report. This document should outline the investigation process, the evidence gathered, and the conclusions reached.

A well-written investigation report is essential not only for internal purposes but also for any external parties, such as regulatory bodies, auditors, or the courts, who may need to review it. Hanzo’s tools can help with exporting data for legal comparison, making it easier to generate accurate reports.

Remedial Actions and Follow-Up

If the investigation confirms any wrongdoing, immediate and appropriate action is crucial. Depending on the issue’s severity, this could involve anything from employee discipline to policy changes, additional training, or legal action.

Once you have addressed the situation, it is essential to monitor the outcome and make any necessary adjustments to prevent future issues. This may involve updating company policies, investing in additional employee training, or enhancing data management systems to ensure ongoing compliance.

Technology’s Role in Streamlining Internal Investigations

Technology plays a key role in enhancing the efficiency, speed, and accuracy of internal investigations. With Hanzo’s Spotlight, Illuminate, and Chronicle tools, enterprises can automate much of the manual work involved in data collection, preservation, and review. These tools are especially valuable if your organization operates across multiple platforms and communication channels.

Some of the key benefits of using technology for in-house investigations include:

  • Time savings: Automation reduces the time needed to gather, sort, and review data, speeding up the investigation process
  • Accuracy and precision: AI-driven tools such as Spotlight can quickly identify relevant information, reducing human error
  • Cost reduction: Technology can significantly lower an internal investigation’s cost by reducing the need for manual labor and minimizing external legal costs
  • Defensibility: Technology solutions help ensure that the investigation process is repeatable, transparent, and defensible, which is especially important in litigation or regulatory review

By leveraging these technology-driven solutions, organizations can conduct internal investigations more efficiently, ensuring compliance, reducing risk, and maintaining trust in an increasingly complex digital landscape.

Frequently Asked Questions

Should you suspend an employee during the investigation?

Suspending an employee during an investigation is not always necessary. Still, suspension may be considered if the investigation’s integrity, workplace safety, or the well-being of other employees are at risk. The company should handle a suspension carefully, following company policies, and only doing so when appropriate.

Can employees bring someone with them to an investigatory meeting?

Yes, in many jurisdictions, employees have the right to bring a colleague or union representative to an investigatory meeting. This allows the employee to feel supported and ensures the process is transparent. It is still important to check local laws and company policies to understand the employee’s specific rights and procedures.

How thorough should the internal investigation be?

The internal investigation should be thorough enough to gather all relevant facts, avoid bias, and determine the truth. It should involve interviewing witnesses, reviewing evidence, and analyzing the context of the situation. A proper investigation helps ensure fair and just outcomes and complies with legal and company standards.

What are the key questions to ask during an internal investigation?

Key questions may include:

  • What happened and when?
  • Who was involved, and what roles did they play?
  • What evidence supports the claims or defenses?
  • Are there any witnesses, and what is their testimony?
  • Has similar behavior occurred before, and how was it handled?

The goal is to uncover all pertinent information, allowing for an objective analysis of the situation.

How can we protect whistleblowers during an investigation?

You can protect whistleblowers by ensuring their confidentiality, avoiding any retaliation, and providing support throughout the investigation process. Reassure whistleblowers that you will protect their identity and ensure their concerns are taken seriously. Implementing a clear whistleblowing policy and establishing channels for anonymous reporting can enhance protection.
