Corporate Espionage: How to Prevent, Detect, and Respond to Threats

Do you know what corporate espionage is, and why it matters? Corporate espionage, also known as industrial espionage or economic espionage, refers to the illegal or unethical gathering of proprietary information, trade secrets, or competitive intelligence by one company from another. This can include stealing physical or digital assets, infiltrating networks or systems, eavesdropping, surveillance, or other covert methods.

The consequences of corporate espionage can be severe and long-lasting for both the victim and the perpetrator. Companies can suffer significant financial losses, damage to reputation, loss of competitive advantage, and legal consequences such as fines, imprisonment, or civil suits. Moreover, it can undermine trust and collaboration among business partners, disrupt supply chains, and ultimately harm the economy.

According to the 2020 Global Economic Crime and Fraud Survey by PwC, 47% of organizations worldwide have experienced economic crime in the past two years, with theft of trade secrets being the third most commonly reported type of economic crime. In the United States, the Federal Bureau of Investigation (FBI) estimates that the cost of economic espionage to US businesses ranges from $100 billion to $400 billion per year.

In this article, we will explore the different types of corporate espionage, the signs to look for, ways to prevent it, and how to investigate and respond to it if it does occur. By staying informed and vigilant, you can help protect your company from the costly and damaging effects of corporate espionage.


Types of Corporate Espionage

There are several types of corporate espionage that companies should be aware of, including:

Competitive intelligence

Competitive intelligence gathering involves collecting information on a company’s competitors in order to gain a strategic advantage. This can include analyzing public data such as financial reports, industry trends, and customer preferences, as well as conducting market research or hiring third-party firms to gather information. While competitive intelligence is legal and ethical, it can become illegal if it involves stealing trade secrets or using illegal methods such as bribery or hacking.

Theft of Trade Secrets 

Theft of trade secrets involves stealing confidential or proprietary information from another company in order to gain a competitive advantage. This can include stealing physical or digital assets such as prototypes, blueprints, customer lists, or product formulas. Trade secret theft is often carried out by insiders such as employees or contractors who have access to sensitive information, but can also involve third-party vendors, hackers, or other outsiders.

One example of trade secret theft is the case of Waymo vs. Uber, in which Waymo accused Uber of stealing its self-driving car technology. Waymo claimed that former employee Anthony Levandowski had stolen trade secrets before leaving to start his own self-driving truck company, which was later acquired by Uber.

Eavesdropping and surveillance

Eavesdropping and surveillance involve monitoring or recording conversations, activities, or data without authorization. This can include using hidden cameras or microphones, wiretapping, or hacking into computer systems or networks. Eavesdropping and surveillance can be carried out by insiders or outsiders and can be especially difficult to detect.

Hacking and cyber espionage

Hacking and cyber espionage involve using technology to gain unauthorized access to computer systems or networks in order to steal or manipulate data. This can include phishing scams, malware, ransomware, or other cyberattacks. Hacking and cyber espionage can be carried out by individuals or organized groups and can be used to steal trade secrets, intellectual property, or sensitive information.

One well-known example of cyber espionage is the case of the 2014 Sony Pictures hack, in which hackers believed to be affiliated with North Korea stole confidential information, including unreleased movies and employee information, and demanded that the studio cancel the release of a movie critical of North Korea.

By understanding the different types of corporate espionage, companies can take steps to protect their valuable assets and prevent unauthorized access to or theft of sensitive information.

Corporate espionage can be difficult to detect as it often involves sophisticated techniques and methods. However, there are some signs that a company may be a target:

Unusual employee behaviour

One of the most common signs is unusual employee behaviour. This can include:

  • An employee who suddenly starts working unusual hours or taking an unusual interest in projects outside of their normal responsibilities.
  • An employee who is unexpectedly resigning or being terminated, especially if they are taking sensitive information with them.
  • An employee who has suddenly become more secretive or defensive, or who refuses to share information with colleagues.

Unusual employee behavior can be a significant red flag that an employee is stealing sensitive information or working for a competitor.

Suspicious Third-Party Activity

Another sign is suspicious third-party activity. This can include:

  • Unexplained visits from vendors, competitors, or other third parties who are not typically involved in your company’s operations
  • Unusual requests for information or data from third-party vendors or contractors.
  • Unusual access to your company’s physical or digital assets by third-party vendors or contractors.


Missing or misplaced items

Another red flag to watch out for is missing or misplaced items. This can include:

  • Missing or misplaced documents or files, especially those containing sensitive information.
  • Missing or misplaced equipment, such as laptops or other digital devices.
  • Missing or misplaced physical prototypes or samples.


Unusual network activity

Finally, unusual network activity can also be a sign of corporate espionage. This can include:

  • Unusual login attempts or failed login attempts.
  • Suspicious activity on your company’s network, such as attempts to access sensitive information or data.
  • Unusual network traffic, such as large amounts of data being transferred to unknown locations.

Some effective strategies for preventing corporate espionage include:

  1. Educate Your Employees: One of the most effective ways is to educate your employees about its risks and how to avoid them. This includes training on security policies, password management, and how to recognize and report suspicious activity. It is important to create a culture of security where employees understand the importance of protecting confidential information and are empowered to take action if they notice any potential threats.
  2. Implement strong access controls: Limiting access to sensitive information is another key strategy for prevention. This can include implementing a least privilege approach, where employees only have access to the information they need to perform their job functions, and using multi-factor authentication to ensure that only authorized individuals can access sensitive data. It is also important to regularly review and update access controls to ensure that they remain effective.
  3. Secure Your Physical Environment: Securing your physical environment is just as important as securing your digital environment. This includes implementing security measures such as surveillance cameras, access control systems, and security guards to prevent unauthorized access to your premises. It is also important to secure documents and other physical assets by using locked cabinets, shredding sensitive documents when they are no longer needed, and keeping an inventory of all physical assets.
  4. Use encryption and other data protection measures: Encryption and other data protection measures can help prevent unauthorized access to sensitive information. This includes encrypting data at rest and in transit, using firewalls and other network security measures to prevent unauthorized access to your network, and implementing intrusion detection and prevention systems to detect and respond to potential threats.
  5. Monitor Your Systems: Regular monitoring of your systems and networks can help detect potential threats before they become serious issues. This includes monitoring for unusual activity, such as attempts to access sensitive information from unauthorized locations or devices, as well as monitoring for signs of malware or other malicious activity. It is important to have a plan in place for responding to potential threats and to regularly review and update your security policies and procedures to ensure that they remain effective.


Investigating and Responding

When it comes to dealing with corporate espionage, prevention is always the best course of action. However, even the most vigilant companies may still fall victim. In such cases, it is important to know how to investigate and respond to incidents effectively:

  • Gather Evidence: The first step in responding is to gather evidence of the incident. It can be collected in various forms, such as emails, documents, videos, and photographs. It’s essential to collect as much evidence as possible, as this will help build a case against the perpetrator.
  • Hire a Professional Investigator: Hiring a professional investigator can be beneficial in many ways. They have the expertise and experience needed to uncover the truth and gather evidence efficiently. They can also help you identify vulnerabilities in your security systems, which can be addressed to prevent future incidents.
  • Notify Law Enforcement: If you suspect that a crime has been committed, it’s crucial to notify law enforcement immediately. They have the resources to investigate the incident and can help you take legal action against the perpetrator.
  • Take Legal Action: If you have evidence of corporate espionage, you can take legal action against the perpetrator. This can include civil lawsuits, criminal charges, or both. It’s essential to consult with a lawyer to determine the best course of action for your situation.
  • Protect your company: It’s crucial to take steps to protect your company from future incidents. This can include improving security systems, conducting background checks on employees and contractors, and implementing policies and procedures to prevent future incidents.
  • Educate Employees: Educating employees about the risks and consequences of corporate espionage can help prevent incidents from occurring. Employees should be trained on how to identify and report suspicious activity, how to protect sensitive information, and what to do in the event of an incident.



Final Thoughts

Corporate espionage is a persistent and evolving threat that businesses must take seriously. It can be difficult to detect and prevent, but by implementing the right strategies and taking a proactive approach, businesses can better protect themselves from the risks.

Effective strategies for prevention include implementing strong security protocols, conducting thorough background checks on employees, and providing regular training to employees. In the event of a suspected espionage incident, businesses should respond quickly and appropriately by conducting an internal investigation, involving law enforcement if necessary, and taking steps to mitigate any damages.

In today’s globalized business environment, the risks are not limited to domestic operations. Businesses must also be vigilant in protecting themselves from the risks of espionage in international settings. This includes conducting thorough due diligence on foreign partners and employees, implementing strong data protection measures, and staying up-to-date on relevant laws and regulations.

By following these strategies, businesses can better protect themselves and ensure their continued success in an increasingly competitive and interconnected world.
