About Us

The ANS Group has set itself the task to increase the added value of its customers by means of an optimized IT adapted to their needs. The unbroken forwarding trend to digitalization is our core issue. As a successful north German company with two other branches, we are implementing projects of various sizes. For us, trust and reliability are essential in our cooperation with our customers as well as in our team. Whether you want to optimize your IT infrastructure, search cost-effective document management, require certified IT solutions for shipping or marine applications, the ANS Group is your partner.

The IT industry has been characterized by high dynamics and steady growth for years. An increasing number of new trends will emerge and will have a decisive impact on the market development of almost every company. These can significantly improve their competitiveness through IT. Our three operational companies of the ANS Group - Active Network Systems GmbH, Active Network Sea Systems GmbH and Cocq Datendienst GmbH - are offering an exceptionally wide range of services. Our customers benefit from the fact that we can achieve a particularly high degree of specialization in different areas while taking advantage of state-of-the-art technologies and "best practices". By consolidating both administrative activities and processes, as well as IT-specific resources and dispensing with paperwork where possible, we work particularly effectively and environmentally consciously.

The ANS Group offers professional, market-proven services in the fields of system integration, document solutions and maritime IT solutions, which our customers have been able to rely on for many years. Whether you need document processing, storage virtualization, or setting up a secure VPN tunnel, ANS Group offers everything from a single source.
