Kiel, August 3, 2026 – The Dierck Group, a long-standing IT systems house with roots dating back to 1883, has announced the acquisition of Tanum Consult GmbH, a Munich-based consulting firm. This strategic move, which took effect in early July 2026, not only expands the Dierck Group’s geographical footprint to include Munich but also significantly enhances its cybersecurity expertise by integrating 20 specialists.
Dierck Group’s Strategic Expansion in IT Services
The Dierck Group has a rich history in the telecommunications sector and has evolved into a diversified IT services provider. Its various member companies operate across different market segments, offering a wide range of solutions from technical building monitoring by Giller-Kähler to classic IT infrastructure services including data centers, printing and scanning systems, networks, cybersecurity, managed services, and various software solutions.
The acquisition of Tanum Consult aligns with the Dierck Group’s strategy to strengthen its position in key IT segments. Tanum Consult, founded in Hamburg in 2001, has established itself as a vendor-neutral IT service provider, particularly recognized for its expertise in cybersecurity. Its employees hold various certifications from industry leaders such as Microsoft, Cisco, and Fortinet, underscoring their advanced technical capabilities.
Leadership and Team Continuity
Following the acquisition, all 20 experts from Tanum Consult will continue their work under the Dierck Group umbrella. Michael Schrader-Boelsche, the current General Manager of Tanum Consult, will remain in his role. Fabian and Wolfgang Ehrk, the leaders of the Dierck Group, will serve as co-managing directors at Tanum Consult, ensuring a smooth integration and continuity in leadership.
This expansion increases the Dierck Group’s total workforce to over 260 employees across five locations: Kiel, Hamburg, Cologne, Berlin, and now Munich. The systems house is also a member of the Compass Group and IT-Union, further solidifying its network and market presence.
Impact on the Cybersecurity Landscape
The addition of Tanum Consult’s specialized cybersecurity team is expected to significantly bolster the Dierck Group’s offerings in this critical area. With the increasing sophistication of cyber threats, the demand for expert cybersecurity services continues to grow. By integrating Tanum Consult’s certified professionals, the Dierck Group is well-positioned to meet these evolving market needs and provide enhanced security solutions to its clients.
Market Trends and Previous Acquisitions
The acquisition reflects a broader trend of consolidation and specialization within the IT services industry. Companies are increasingly seeking to expand their capabilities through strategic mergers and acquisitions to offer comprehensive solutions and gain a competitive edge. Recent activities in the market include Citadelle’s expansion in Saxony (July 2026), Axians’ parent company’s move to acquire All for One (July 2026), and Gordion joining the Dierck Group (January 2022).
The Compass Group, of which Dierck Group is a member, also reported record revenues in May 2025, indicating a robust and growing market for IT services. The security meet-up of the Compass Group in April 2025 further highlights the industry’s focus on cybersecurity and collaboration among key players.
Future Outlook for Dierck Group
With its expanded team and geographical reach, the Dierck Group is poised for continued growth and innovation in the IT services sector. The integration of Tanum Consult’s cybersecurity expertise will enable the group to offer more comprehensive and specialized solutions, particularly in an era where digital security is paramount for businesses across all industries.
The company’s long history and commitment to diverse market segments, combined with its strategic acquisitions, position it as a key player in the German IT landscape. The strengthened presence in Munich, a major economic hub, further enhances its ability to serve a broader client base and capitalize on new opportunities in the region.
