As a competent partner, we bring german as well as international companies and public organizations to the next level of security awareness and make them pioneers in the field of cyber security.

The DGC-Story


Our journey started in 2000. Back then, as an IT service provider we served many local companies for whom we implemented individual solutions for web design, web hosting and general IT service. After a few years, this business model evolved further towards IT security in the form of penetration testing, which became the core business of the company after 2015.

In the following years, we established a reputation by performing penetration testing and IT forensics for various financial institutions and critical infrastructure operators in Germany and Switzerland.

In 2018, we launched our first software cyberscan.io® , automating penetration testing and IT infrastructure monitoring.

The company is independently managed by the sole managing partner Matthias Nehls. Our headquarters are located in Flensburg, in the far north of Germany.
