Cyber Security:
Making digital
transformation secure

We manage the risks of your digital transformation

Our Mission

As one of the leading providers of cyber security, the DGC supports companies in taking advantage of the opportunities offered by the digital transformation – and in minimizing the associated risks.

With our holistic approach and our own products, we ensure a comprehensive cyber security and IT related risk management. Whether through a simulated hacker attack, a cyber security awareness training, advice on security standards or emergency services in the event of IT security incidents: With us you receive comprehensive solution packages for your cyber security – customized, up-to-date and from a single source.

We create

Awareness for Cyber Security

Data leak, phishing attempt or AI related threats: What risks are companies exposed to in the event of attacks from the net? What are the IT weaknesses? We raise awareness on potential dangers and show how the cyber security could be optimized. 

Digital Resilience

To respond to cyber attacks before they damage the company: Companies need to take action today in order to be able to respond to attacks tomorrow. As a strategic, tactical and operational ally we share our expertise and do everything we can to make you resistant and empower you for defensive response activities.


After revealing the weaknesses that could have a damaging impact on your business, we identify optimization potentials: This makes every IT risk editable to facilitate remediation. The goal is the comprehensive network security of your company.

We minimize

IT Vulnerabilities

IT threat situations are mostly complex and not visible to the companies. We show you the weak points and support you in better fending off cyber attacks in the future. With our technique and tactics we are always one step ahead.

Attack Potentials

Better identifying and assessing dangers and risks from the network is the first step towards cyber security. We will show you how to do this in our IT security awareness training courses. Furthermore, in case of an emergency, we will help you to defend yourself appropriately.


In the event of a cyber attack, many companies still react erratically and thoughtlessly. It is our task to create awareness of the situation and to minimize uncertainties. For us, creating cyber security means to enable you to act decisively.

We secure

IT Infrastructures

Digital infrastructures constitute the backbone of every company. We are your reliable security partner, who uncovers the risks in the network – inside and outside – and manage them to protect your network services including decentralized ways of working.

Company Assets

We support companies to ensure that only the information which should be available is available. In this way, the company value – in the form of assets, sensitive data or (capital) investments – is effectively secured.

Trade Secrets

Intellectual property and confidential processes are essential for companies to remain competitive. We protect your valuable information and ensure that only unrestricted or clearly identified data is accessible.
