3-core gmbh is an independent, management consultancy. We aim to establish and optimize a client’s security management structure in order to strengthen the resilience of their company.

“Guns, Gates, and Guards” is what we let others do.


3-core gmbh has five main topics which focus on a risk-based approach. They are:

Security Governance

Optimization or development of the control structure of the security management to fulfill the legal requirements and the social responsibility. This sets the course for handling all other security issues in the company.


Crisis Management

We optimize or design your crisis management manual individually tailored to your company. Through simulations or training for the respective roles in the crisis team, we sharpen the understanding of roles and increase the security of action.


Security Marketing

Increasing the visibility of security in the company, optimizing the presence via internal communication media, sustainable communication of the security content to the employees – increasing security awareness in the company.


Travel Security Trainings

“Hands on” training for travel security, live simulation to deal with stress situations, behavior in emergencies.


Emergency Response / BCM

The aim of emergency management is to ensure the functionality of business-critical business processes and resources. Critical business processes are identified and evaluated in an early stage (Business Impact Analysis). We work with you to determine a continuity strategy individually tailored to your company. We prepare your company to react to emergencies in a structured and prepared manner through training and coaching on various emergency scenarios.


Security Concepts

We rely on risk-based protection concepts for plants and buildings that are created by independent experts and meet the defined protection goals in the interests of the company. Parts of the security concepts focusing on site protection can be an access concept, camera concept, protest management or emergency processes. Requirements for the safety of buildings and infrastructures can be based on requirements of standards such as ISO 27001, and also for the company’s own interest in protecting its own equipment against sabotage, industrial espionage and theft.


International Protection

Security of projects and employees in developing and emerging countries at increased risk. We create macro analyzes of the political situation / security situation and a security concept for the protection of employees and assets.



Our goal is that your company is optimally prepared and protected against current and future threats.

_How do we do it?

As an independent, consulting company, our goal is to offer solutions that focus on prevention. Our way of working is characterized by professionalism, transparency, and efficiency.

The optimal security strategy is not a one-size-fits-all approach. Every company is unique in its vision, strategy and organisation.
Different stakeholders such as owners, employees, customers, and authorities set different parameters for how your company should deal with security risks. But all these stakeholders have one thing in common: the conviction that a company needs to know what risks exist.

 “You want to concentrate on your core business and not on security? We will help you!”
