What is an Insider Threat Test?
An Insider Threat Test is a practical assessment where Cocoon executes pre-agreed scenarios from the perspective of an internal actor, such as an employee, supplier, or contractor with legitimate access. The test measures whether technical and organizational security measures actually prevent or detect the misuse of that access, and how mature the organization’s security culture is.
This service is relevant for organizations that want to know if their security holds up when the threat is already within the organization, which is something most security investments do not focus on. An Insider Threat Test is often deployed after an incident involving an employee or supplier, when there are doubts about the willingness to report within the organization, or as a supplement to physical and digital penetration tests that primarily focus on external threats.

How an Insider Threat Test works at Cocoon
With many alternatives, attention to insider threats is limited to digital detection tools such as monitoring and logging, or to a paper-based risk analysis. Human behavior, leadership, and the actual willingness of employees to report remain untested, even though these are precisely the factors that determine whether an organization detects an insider in time.
An Insider Threat Test also follows our standard setup. During preparation, we jointly define the scope, objectives, and rules of engagement, and establish which authorizations and scenarios will be used. During execution, our specialists act from the perspective of an internal actor, within those pre-agreed frameworks, and we observe not only security measures but also behavior: is anomalous behavior recognized, do colleagues dare to address each other, are suspicious situations actually reported?
Specifically, we test, among other things:
- Security awareness of employees
- Culture of accountability and exemplary behavior of managers
- Willingness to report anomalous or suspicious behavior
- Collaboration between physical security, IT, and management
- Compliance with procedures and handling of confidential information
- Detection through monitoring and logging
- Alignment between authorizations and actual job duties
After execution, a debriefing is held with those involved, where we not only share the findings but also immediately discuss what this means for the security culture. Finally, you receive a report with an objective overview of both technical resilience and the maturity of your security culture, including concrete improvement measures, KPIs, and input for a continuous improvement program.
Why choose Cocoon
“We don't just test if your security works. We test if your organization acts securely.”
For Cocoon, an Insider Threat Test is the instrument that reveals what happens after successful access—the scenario that most security investments leave untested. We do not assess our own delivered security measures, which makes our findings objective. Our team combines knowledge of physical security, behavior, and organizational cultures.
Cocoon distinguishes three complementary test forms:
- Independent validation, separate from provided security systems
- Combination of physical, organizational, and human expertise
- Objective baseline measurement of security culture, not just technology
Please note: under NIS2 and the General Security Requirements for Central Government Commissions (ABRO), actual testing of security measures is required.
Performing an Insider Threat test helps meet the requirements of NIS 2 and ABRO.
Cocoon works for renowned (publicly) listed companies in profit and non-profit environments; references are available upon request.
Frequently asked questions
What is the cost of an Insider Threat Test?
The cost of an Insider Threat Test depends on the scope, the number of scenarios, and the size of the organization. Following the intake, you will receive a custom quote tailored to your objectives.
How long does an Insider Threat Test take?
An Insider Threat Test typically takes several weeks, from intake to reporting. A debriefing follows immediately after execution, so you do not have to wait for the report for the initial insights.
Is an Insider Threat Test Legal?
Yes. An Insider Threat Test is exclusively conducted with the client’s written consent, within pre-agreed authorities and Rules of Engagement. These frameworks ensure that the test proceeds lawfully and in a controlled manner.
What is the difference between an Insider Threat Test and a Social Engineering Assessment?
A Social Engineering Assessment primarily tests whether employees recognize external manipulation, such as phishing or an unknown visitor. An Insider Threat Test simulates a threat that already has legitimate access, such as an employee or vendor, and focuses on whether the abuse of that access is detected and reported.
What is the Difference Between an Insider Threat Test and a Physical Penetration Test?
A physical penetration test assesses whether an unauthorized outsider can gain access. An Insider Threat Test goes a step further, investigating what occurs when someone who already has access misuses it.
Is this tested without employees’ knowledge?
Yes, employees are not informed in advance, ensuring the test measures their actual behavior. The client is informed internally in advance about the scope and scenarios, and the results are never used to penalize individual employees.
Is Insider Threat Solely an IT Risk?
No. Many organizations primarily treat insider threat as a digital detection issue, with monitoring and logging as the solution. Cocoon assesses the full breadth: behavior, leadership, procedures, and physical access, in addition to the technical aspects.
