What is an insider threat?

Threat illustration

An insider threat is a security threat or risk that emerges from within a company. This can be employees, business partners, or contractors with insider knowledge about the organization’s data, security practices, and computer systems.

The threat can be intentional or unintentional and poses a significant risk to the organization’s intellectual property, sensitive data, and overall security. So, insider threats require a comprehensive detection, prevention, and response approach.

Here are the main categories of insider threats:

1. Malicious insider

These individuals, often called ‘Turncloaks,’ exploit their credentials with intentions. They are mainly motivated by gain or personal incentives. For example, this can be individuals who hold grudges against employers or opportunistic employees who sell information to competitors. Malicious insiders have the upper hand because they know about an organization’s security policies, procedures, and vulnerabilities.

2. Careless insider

This category consists of unwitting individuals who unintentionally expose the system to threats. It is often a result of mistakes such as leaving a device unprotected or falling victim to a scam. For instance, an employee with no intent might unknowingly click on an insecure link, introducing malware into the system.

3. A mole

Although technically outsiders, these individuals manage to infiltrate a network within an organization by posing as insiders. They can be sources that impersonate employees or partners to gain access.

Key statistics highlighting the severity of insider threats

Insider Threats Statistics
  • US businesses face 2,200 internal security breaches daily.
  • Globally, 34% of businesses deal with insider threats annually.
  • 66% of organizations prioritize insider attacks over external ones.
  • Insider incidents surged by 47% in the last two years.
  • In 2022, the cost per insider threat was $15.38 million.
  • Over 70% of insider attacks remain unreported externally.
  • Trusted business partners account for 15-25% of insider incidents.
  • 53% find insider attack detection challenging in the cloud.

Detecting and preventing insider attacks takes time

The consequences of an insider attack become more severe the longer it remains uncontained. Some incidents may even take months or years before they are detected. This is because cybercriminals know exactly what data they are looking for and the solutions that might be implemented to protect the data.

The process becomes even more complicated if it is an unintentional insider. The victim must track all company employees’ actions to know the root cause of the problem.

On average, it takes 85 days to detect and manage an insider threat. However, only 12% of the threats are contained in less than 31 days. The rest usually takes time. For instance, 34% of insider threats take more than 91 days to be contained. Further, 29% take 62 to 91 days, while 25% take 31 to 61 days to address.

5 different phases determine how difficult it is to detect and contain an insider threat. They include:

  • Reconnaissance phase (49%)
  • Circumvention phase (47%)
  • Aggregation phase (53%)
  • Obfuscation phase (42%)
  • Exfiltration phase (40%)

Top insider threat statistics you must know

Insider attacks vectors


Insider attacks can be grouped into two main vectors: Privilege misuse and Miscellaneous errors.

Privilege misuse

Privilege misuse occurs when individuals inappropriately use their privileges to gain access, often motivated by financial interests. In most cases, privilege misuse is in the form of data mishandling and privilege abuse.

Mishandling of sensitive data accounts for about 80%, while privilege abuse accounts for 20% of privilege misuse incidents. The two terms differ in that data mishandling cases do not have malicious intent as opposed to privilege abuse.

Miscellaneous errors

These are unintentional acts by internal individuals. Often, parties that commit those errors usually have access rights to systems. Such individuals include developers, system administrators, and other end users. Most errors committed under this vector include misdelivery (40%), misconfiguration (40%), programming errors, and publishing, among other errors (20%).

Main reasons for insider threat incidents

Risks Illustration

These are some of the reasons why insider threat incidents occur. 

Credential theft

This accounts for 18% of overall insider threat incidents. It is one of the most prevalent methods for breaching an organization’s secure perimeter. By acquiring legitimate credentials, hackers can clandestinely operate within a system for an extended period without detection. Perpetrators employ various tactics such as social engineering, brute force attacks, and credential stuffing to obtain user logins and passwords.

Criminal and malicious insiders 

Given their intimate knowledge of your organization’s cybersecurity protocols and sensitive data, this represents a significant menace. Armed with this information, they can engage in actions like data theft, data leakage, operational sabotage, or even facilitate external attackers’ access to your resources.

Employee or contractor negligence

The category of employee or contractor negligence ranks as the primary cause behind most insider threat security incidents. However, the silver lining is that the consequences of these incidents typically entail lower mitigation costs. Instances of human error include mishaps like sending sensitive data to the wrong recipient, misconfiguring system settings, and practicing unsafe work habits.

Factors contributing to new insider threat risks

New insider threat challenges have emerged over the years due to various factors:

Cloud insider attacks

This attack occurs due to access to a company’s cloud services. Unlike physical or on-premises attacks, cloud-based attacks are often harder to detect and deal with.

Supply chain attacks

These types of attacks take place within the supply chain process. In other words, attackers target vulnerabilities within the supply chain by compromising suppliers or gaining unauthorized access to an organization’s data. According to Gartner, supply chain attacks will likely increase by 45% by 2025.

Hybrid office environments

Although new in insider threats, this attack has recently gained attention. Under this factor, subordinates combine in-office and remote work to execute threats. As the workplace transitions to a hybrid environment, most employers are becoming more concerned about this attack.

Cost of insider threats

The cost of insider threats wasn’t directly proportional to the actual damage caused, as reported by most victim organizations. The total cost of insider threats is categorized as follows.

  • Direct costs: This includes the funds required to detect, mitigate, look into, and address the threat.
  • Indirect costs: This entails the value of human labor and other resources used in remediating the incident.
  • Lost opportunity costs: Includes losses incurred as a result of the breach.

The total cost of insider threat incidents in 2018, 2020, and 2022 was estimated to be $8.76 million, $11.45 million, and $15.4 million, respectively.

North America is one of the major victims of insider threat incidents whose costs rose from $11.1 million to $17.53 million in a period of 4 years. The average total spending required to address a single incident shot up to 85% from 2016 to 2022.

It’s important to detect the threat early enough to avoid the devastating impact of insider threats. Otherwise, the cost involved in observing, investigating, responding, containing, and ex-post analysis could result in severe financial outcomes for your firm.

Ways to protect against an insider attack

Online safety tips

You can take several proactive steps to mitigate the risk of insider threats. In light of the available insider threat statistics, below, we list some of the obvious measures to contain the risks.

1. Protect critical assets

Identify and safeguard both physical and digital critical assets. This includes systems, technology, facilities, and even personnel. Intellectual property, such as customer data, proprietary software, schematics, and internal manufacturing processes, is also part of this category.

Develop a comprehensive understanding of your critical assets by asking what assets are crucial to our organization. Can we prioritize them effectively? What is the current status of each asset?

2. Enforce policies

Document organizational policies clearly to facilitate enforcement and prevent misunderstandings. Ensure that every member of the organization is familiar with security procedures and comprehends their rights concerning intellectual property (IP). This knowledge will help prevent the accidental sharing of privileged content created by employees.

3. Increase visibility

Implement solutions that enable you to monitor employee actions and consolidate information from various data sources. For instance, deploying deception technology can help draw in malicious insiders or impostors, providing you with insight into their activities and intentions.

4. Promote cultural changes

Recognize that security isn’t solely about knowledge; it also encompasses attitudes and beliefs. So, educate your employees on security issues and work to enhance overall employee satisfaction to address negligence and the underlying drivers of malicious behavior. Creating a security-conscious culture can significantly reduce insider threat risks.


Insider threats pose a significant threat to businesses and their profitability. Unfortunately, there has been a steady increase in insider threats, according to the latest statistics.

As IT systems and cybercriminals become more complex and sophisticated and third-party vendors increase in numbers, we are set to see an even further surge of insider attacks in the coming years. Therefore, there is a need to take proactive measures to prevent these measures and mitigate their effects.


Insider attacks are caused by individuals who can access a company’s sensitive data. They can either be employees, suppliers, or other third parties.

Insider risks include employees mishandling critical documents, divulging confidential information to competitors, unwittingly clicking on malicious links, or falling prey to phishing emails containing viruses.

In the world of cybersecurity, insider threats account for a substantial 60% of all cyber attacks. Given the challenges associated with their detection, these threats can sometimes be mistaken for external ones.

Failure to detect insider threats promptly can inflict significant harm on your business. Malicious insider threat statistics underscore that the longer such attacks remain undetected, the more detrimental their impact becomes for a company.

You can protect your company from insider threats by monitoring your employees’ activities, training them about cybersecurity threats, and implementing enough security measures against insider attacks.

Insider threats make up 60% of the total data breaches.

Most insider threats are a result of careless insiders. Negligence plays a key role in propagating insider threats.

Some common indicators include unusual logins, excessive downloading of company data, repeated login attempts, unusual employee behavior, and an increased number of individuals with access privileges.
