What is corporate espionage?

Corporate espionage is the illegal acquisition, use, or disclosure of confidential business information to benefit another party. Trade secrets are the main target of espionage.

Corporate espionage typically targets product roadmaps, source code, algorithms, formulas, chip designs, prototypes, customer lists, pricing, sales playbooks, manufacturing processes, bids, and other trade secrets.

Corporate vs. industrial vs. economic espionage

These targets also feature in industrial and economic espionage. While these types of espionage often overlap, the main distinction lies in who acts and with what intent. 

Industrial espionage is a form of corporate espionage that focuses on engineering, scientific, manufacturing, or technological information. Common targets include production methods, energy technology, pharmaceutical research, and prototype specifications.

Economic espionage is a form of corporate espionage in which trade secrets or other proprietary information are acquired to benefit a foreign government, foreign instrumentality, or foreign agent. Common targets include advanced technologies, defense-related research, energy systems, manufacturing processes, pharmaceutical and biotechnology data, and other information with strategic economic value.

Targets of espionage

Any organization with valuable non-public information can become a target. Risk is especially high in industries where innovation requires large investments, product cycles are long, and global competition is intense.

Industries that rely heavily on research and development (R&D),  including computer hardware manufacturing, IT, automotive, energy, aerospace, and chemicals, should be extra cautious. R&D often involves innovative solutions and technologies that are costly to develop, making them a desirable target for spies.

Retail, finance, and the public sector are also heavily targeted in cyberattacks, as they are highly competitive and often suffer from a lack of investment in cybersecurity.

Sectors at risk	Data targets
Computer hardware	Chip designs, manufacturing processes, and hardware specifications.
IT	Innovative software solutions, cybersecurity protocols, and cloud computing technologies.
Finance	Customer information, investment strategies, and trading algorithms.
Energy	Energy production methods, alternative energy sources, and next-generation power grid technologies.
Aerospace	Aircraft designs, avionics technology, and advancements in propulsion systems.
Automotive	Innovative engine design, increased fuel efficiency, autonomous driving software, and future vehicle concepts.
Biotechnology	Research results in areas like gene editing, pharmaceuticals, and medical devices.
Chemicals	Secret formulas, efficient production processes, and proprietary chemical compounds.
Public administration	Classified information on national security strategies, defense capabilities, or fragile negotiations.
Retail	Customer data, marketing plans, and future product rollouts.

Forms of corporate espionage

Here’s a breakdown of the most common forms of corporate espionage, considering the types of data at risk:

• Trade secret theft. A trade secret generally refers to sensitive information about existing products or those under development. If stolen, this data may help your rivals gain a competitive advantage.
• Client information theft. Data about your clients, including their financial information, can be exploited to lure your clients over to a rival company. Another possible scenario is exposing illegally acquired data to the public, thus damaging your company’s reputation.
• Financial information theft. Your company’s financial data can be used to offer better deals to your clients and partners, win bids, and even make better offers to your valuable employees.
• Marketing information theft. With this information, competitors can prepare a timely response to your marketing campaigns and render them ineffective.

Who commits corporate espionage and why

The main motive of these attackers is usually to gain some form of strategic advantage: faster product development, financial gain, customer poaching, market manipulation, supply-chain intelligence, or support for a state objective. Sometimes attackers want to steal the secret itself; in other cases, they only need to become familiar with insider information to make a better bid, reproduce a feature, or anticipate a strategic move.

Actors can include direct competitors, nation-state groups, planted or recruited insiders, such as departing employees, contractors, and vendors. 

How does corporate espionage affect businesses?

Unauthorized access to trade secrets, intellectual property, and other sensitive information can have a profound and far-reaching impact on your business. Potential negative consequences include:

• Loss of competitive advantage. Losing confidential information can cripple your company’s competitive edge. Competitors with access to stolen secrets can develop similar products or marketing strategies, making it difficult for your business to compete.
• Reputational damage. A successful espionage attack can damage your organization’s reputation for innovation and security. This can erode customer trust and make it harder to attract investors and partners.
• Legal implications. Depending on the nature of the stolen information, you may face legal ramifications. These could include lawsuits from investors or partners who also suffered from the espionage attack on your organization.
• National security risks. In some cases, industrial or economic espionage can have national security implications. Stolen information related to defense technologies or sensitive government projects could pose a threat to national security.
• Financial loss. The most common consequence of industrial espionage is the exposure of your intellectual property, which can lead to significant financial losses. Other consequences such as reputational damage and legal issues may also erode market shares and reduce profits. 

The severity of the consequences depends on the type of information stolen and how it’s used. 

Is corporate espionage illegal?

Whereas gathering non-confidential information by attending industry events or via open-source research is legal, stealing confidential information from competitors is not.

Depending on the severity of the offense and the laws violated, individuals involved in corporate espionage can face criminal charges. Penalties may include imprisonment and fines.

In the United States, the Economic Espionage Act of 1996 criminalizes trade secret theft. Section 1832 carries up to 10 years in prison for an individual, while Section 1831 covers theft intended to benefit a foreign government, instrumentality, or agent, and carries up to 15 years. The Defend Trade Secrets Act of 2016 also provides trade secret owners with a federal and civil course of action. Courts can grant injunctions, damages, and orders intended to prevent further dissemination of information.

In the EU, Directive (EU) 2016/943 requires member states to provide remedies for the unlawful acquisition, use, or disclosure of trade secrets. It also treats unauthorized access to protected files or copying those files without authorization as unlawful. 

In the UK, Section 2 of the National Security Act 2023 criminalizes unauthorized obtaining, copying, recording, retention, or disclosure of trade secrets when the foreign-power condition is met.

Unfortunately, detecting and proving corporate espionage and holding perpetrators accountable can be challenging, especially when it involves intangible information like trade secrets and unidentified foreign state actors.

Methods of espionage

Corporate espionage rarely resembles a spy movie. An attacker may compromise a privileged account, recruit a trusted employee, exploit vendor access, or use a backdoor account left after an employee’s termination. 

Cyberattacks

Cyberattacks are hostile attempts to steal, compromise, change, or destroy information by gaining unauthorized access to an organization’s computer systems.

External attackers may exploit unpatched vulnerabilities, steal credentials, compromise accounts, and deploy malware. They also use phishing, adversary-in-the-middle attacks, password spraying, token theft, SQL injection, and supply chain attacks to access your business intelligence.

Technique	Description
Hacking and malware	Compromise of endpoints or servers to steal confidential data or credentials.
Phishing	Tricking employees into revealing credentials or downloading malicious apps.
Eavesdropping	Interception of sensitive information moving across poorly protected channels.
Man-in-the-middle attacks	Intercepting traffic between users or systems, often through network spoofing, to capture sensitive communications.
SQL injection	Inserting malicious SQL commands into vulnerable application inputs to read or modify database content.
Exploiting poor security practices	Guessing weak passwords, using excessive privileges, or exposing insecure remote access to steal sensitive corporate data.

The majority of companies have up-to-date malware protection and network security, but only a few think about incident response plans, control of storage devices, and formal policies.

Moreover, cyber breaches are often preceded by physical access that makes them possible. That’s why even sophisticated anti-malware protection and firewalls are not enough when insider and cyber threats are linked.

Insider threats

Insider threats are particularly difficult to detect because their activity often appears legitimate. The 2025 Insider Risk Report by Cybersecurity Insiders reveals that 93% of organizations consider insider threats as difficult or more difficult to detect than external attacks. 

Threats may be posed by:

• A malicious employee or vendor motivated by personal gain, revenge, a competitor, or a foreign state.
• A departing employee who believes that technology they helped develop belongs to them or wants leverage in a new role.
• A recruited insider bribed by an outside actor.
• A negligent employee outsmarted by social engineering attacks.
• An identity taken over by an external attacker.

How a corporate espionage campaign unfolds 

An espionage campaign typically unfolds as follows: target selection → access → lateral movement → data collection and exfiltration → covering tracks. 

The attacker’s key goal is to exfiltrate data and make every action look legitimate. 

Why does espionage often go unnoticed?

There are several reasons why companies often don’t detect or report cases of corporate espionage:

• Industrial espionage is hard to identify. Most malicious actions by insiders remain indistinguishable from normal everyday activities. Even your most valuable employee with access to sensitive data may act as a double agent without you noticing for a long time.
• It’s hard to hold perpetrators accountable. Laws on trade secrets and industrial espionage vary across the globe. If you have detected an international spy, it may be very hard to hold foreign companies and governments accountable. And even if the perpetrator is domestic, they can prolong legal procedures to the point where it’s not feasible for your company to continue pursuing the case.
• It may harm your stock price. The value of your company’s stock may fall if it becomes publicly known that your security has been breached. This can affect the company’s reputation and contribute to market pressure. To avoid amplifying these risks, organizations may limit public communications about an incident, particularly when disclosure is not legally required.
• It can be seen as a violation of IT compliance requirements. A company is responsible for ensuring the security of its customers’ sensitive data. In many countries and industries, if this data is leaked or stolen by industrial spies, the company will be fined. These risks can also discourage companies from publicly disclosing incidents beyond what applicable requirements demand.

All of these factors compel companies to keep cases of espionage to themselves and conduct internal investigations.

Real corporate espionage cases

Even industry giants can fall victim to industrial spies. Let’s take a look at some corporate espionage cases that have been made public.

Rippling and Deel: Insider recruitment

In March 2025, Rippling sued rival HR software company Deel, alleging that Deel recruited a former Rippling employee to steal trade secrets and internal information. An investigation revealed that the employee conducted more than 6,000 searches across Slack channels and accessed or downloaded customer lists on more than 600 occasions. 

Google AI trade secret theft

In January 2026, a federal jury convicted former Google engineer Linwei “Leon” Ding on seven counts of economic espionage and seven counts of theft of trade secrets involving Google AI technology. According to the Justice Department, Ding took more than 2,000 pages of confidential AI information, uploaded it to a personal Google Cloud account, and later downloaded the stolen material to his personal computer less than two weeks before resigning.

Philips X-ray technology theft

A case involving theft of proprietary X-ray technology reached a verdict in August 2026. A former Philips engineer, Chih-Yee Jen, was convicted of conspiring to steal trade secrets. Prosecutors stated that Jen copied confidential X-ray technology from Philips’ internal databases while still employed there and later used it in work connected to a Chinese competitor. 

Common warning signs of corporate espionage

These cases illustrate how employees can misuse legitimate access to obtain sensitive information. Detecting that misuse starts with recognizing when everyday activity becomes illegitimate. 

Common warning signs include:

• Access to projects, customers, repositories, or systems outside the user’s role.
• Unusual search activity across confidential data.
• Bulk downloads, archive creation, screenshots, and mass printing.
• File uploads to personal email and cloud storage services.
• Use of new, unauthorized USB devices.
• Access during unusual hours, from atypical locations.
• Attempts to disable monitoring, clear logs, bypass controls, or rename files.
• Repeated access denials followed by privilege changes.
• Use of dormant, shared, or previously unknown privileged accounts.
• Retention of access after role change, contract completion, or termination.

Recognizing these warning signs is only the first step. You also need preventive controls that limit opportunities for espionage and make suspicious activity easier to detect, stop, and investigate. The following practices can help you build a strong defense against corporate espionage. 

7 best practices to detect and prevent corporate espionage

The strongest way to prevent corporate espionage is to develop a comprehensive strategy: know which information matters, limit who can reach it, verify identities, oversee user sessions, stop suspicious activity, and preserve evidence. 

1. Conduct a risk assessment

Start by identifying the information that could cause the most damage if a competitor obtains it. You need to know what trade secrets and other valuable data your company possesses and how desirable they are to your competitors. You can evaluate the attractiveness of your trade secrets by comparing them with products already available on the market or with the known assets of your competitors. Map where each trade secret resides, who owns it, who can access it, which third parties handle it, and how it could leave the environment.

Risk assessment is one of the keys to a risk-based security approach, which should be part of every organization’s security strategy. Use assessment findings to select appropriate protection measures for each asset at risk, based on the threats it faces and the potential business impact of its exposure. 

2. Secure your infrastructure

Establishing a secure perimeter around your company’s network is one of the pillars of cybersecurity. To prevent corporate espionage, enhance your security at multiple levels. Make sure to separate your valuable data from your corporate network and limit access to it.

Use multi-factor authentication (MFA) and implement a zero trust approach to continuously validate users within your corporate network. The core idea of this approach is that every time a user tries to access critical resources, they must verify their identity. 

Discover unmanaged accounts across your environment and disable dormant ones wherever possible, since departing employees may create backdoors for quietly exfiltrating data. 

3. Establish effective security policies

Establish a set of rules that will minimize the risks of espionage, and formalize these rules in a clearly written cybersecurity policy.

Build the rules based on the risks you’ve identified.

While composing your cybersecurity policy, consider rules covering the following topics:

• Network security. Include guidelines for computer network access, describe the architecture of your network security environment, and explain how security rules are implemented within it.
• Security awareness. Describe measures aimed at informing your personnel about your security procedures and mechanisms.
• Employee onboarding/termination. Define procedures for proper employee onboarding and termination in terms of security.
• Password management. Establish strict rules on how passwords must be created, stored, and managed in your organization.
• Access management. Specify procedures for providing access to various categories of data and systems for regular and privileged users, considering the concerns and risks of remote work.
• Audit and accountability. Describe how your system activity is monitored, analyzed, and investigated.
• Incident response. Develop a plan for what your personnel will do if a cybersecurity incident is detected.

Make sure all your employees and third parties know and follow the security rules you have developed.

Take a look at the NIST security guidelines. Depending on the type of your organization, these guidelines will help you meet the security requirements of NIST 800-53, FISMA, HIPAA, and PCI DSS. 

4. Address security risks among your employees

The people you work with are crucial for sustaining a healthy and secure environment in your company. Whether it’s intentional or not, it’s frequently someone on an organization’s staff who’s responsible for industrial espionage.

As a responsible employer, you should hold yourself accountable for the trustworthiness of your personnel and eliminate all human-related risks.

Educate employees on cybersecurity risks

Make sure your employees know what insider threats are and what dangers they pose. Regularly conduct cybersecurity awareness training and explain how trade secrets are targeted, how social engineering attacks work, and why seemingly harmless actions like forwarding a file to a personal email or pasting source code into an unapproved AI tool pose risks. 

Make employees aware of their role in the organization’s cybersecurity and how they can help you improve it.

Conduct employee background checks

Before hiring someone, your HR department should conduct a background check. This minimizes the risk of a spy infiltrating your organization.

It can be helpful to repeat these checks once in a while, especially for employees with privileged access, to ensure they don’t become spies.

Create a proper termination procedure

Corporate espionage is often performed in the last couple of weeks of employment, or even after termination. This becomes possible if the credentials of a terminated employee remain active, which can enable them to freely access the organization’s sensitive data without anyone noticing.

Create and implement a proper employee termination procedure to protect your company from potential espionage attempts by former employees.

5. Monitor session activity

Monitoring session activity is the most common and effective measure for preventing corporate espionage. It’s especially important to pay attention to privileged users with access to your trade secrets, as they can easily gather intelligence while performing their legitimate roles.

Monitor user sessions and configure alerts for such activity as:

• Uploading specific files.
• Using shadow AI.
• Running suspicious apps.
• Connecting unapproved USB devices.
• Accessing sensitive systems outside approved hours.
• Attempting to stop security tools.

You should also be able to connect alerts to session context, quickly review the session, verify intent, and block a user or kill a process when necessary.

6. Manage data access 

Many companies provide all their employees with access to critical data and infrastructure by default. But while it may be convenient, this approach is not secure.

Apply the principle of least privilege and the role-based access control model to ensure that employees, administrators, service accounts, vendors, and contractors receive only the permissions required for their tasks. Replace standing privileges with just-in-time access privileges that expire when the task ends. 

Regularly review permissions after role changes, project completion, and contract termination. 

7. Develop an incident response plan

Design a plan to follow if you detect an incident. An incident response plan (IRP) describes who does what when responding to a detected incident. Document who should isolate accounts, terminate access, contact legal counsel, and notify executives. Additionally, establish procedures for preserving logs, session recordings, and other evidence for investigations.
