Lift up security, together: our 5 learnings from the Hamburg Cyber Security Days 2025
How do we strengthen information security together with other companies? This is shown by our review of the second Hamburg Cyber Security Days.
Cyber attacks have long been part of everyday life: phishing, social engineering, malware and ransomware affect companies from all industries, in particular the manufacturing industry. The damage is enormous — financially, organizationally and reputatively. It is therefore all the more important to understand cybersecurity not only as the responsibility of the relevant departments, information security and IT, but as a joint responsibility of the entire company.
That is exactly why we have created the Hamburg Cyber Security Days (HCSD) together with other Hamburg-based companies, in line with our motto: Lift up security, together. The second edition — in keeping with International Cyber Security Awareness Month — took place in October 2025 and brought together employees, experts, service providers and organizations. The goal: to share knowledge, use synergies and make Hamburg's companies more resistant to cyber attacks. A total of more than 1,800 Jungheinrich employees took part — a strong sign of interest in the topic.
Who was there with us
Following the successful start of 2024, we have further expanded the 2025 initiative together with the following partners:
Our highlights from HCSD 2025
This year's Hamburg Cyber Security Days offered a diverse program of lectures, panels and interactive workshops — with content for different target groups: Jungheinrich colleagues shared practical knowledge on current threats, awareness strategies and protective measures. Service providers such as Microsoft, Proofpoint, Amazon Web Services, YesWeHack or SoSafe presented trends and best practices from corporate practice. Organizations such as Deutschland sicher im Netz e.V. and Hackers4Good e.V. showed how important education and networking are in the digital society. And contributions from government agencies, the Open Worldwide Application Security Project (OWASP) and ethical hackers such as Donald Ortmann provided insights into attacks, risks, and defense mechanisms.
In addition, practical formats provided an immediate learning effect, such as the “Your phishing email” workshop with real examples from everyday working life and the HackAttack board game, which was a fun way to learn how to deal with threat scenarios. In addition to the official program, the discussions between sessions were also valuable: We shared experiences, developed ideas and started new collaborations.
Insights into HCSD 2025
Our 5 key learnings
HCSD 2025 has once again shown that cybersecurity goes far beyond technical solutions — it is culture, responsibility and collaboration. Our key learnings:
- Security can only be achieved in networks: Cooperation across company borders creates new perspectives, accelerates solutions and promotes innovation.
- Practice creates awareness: Real scenarios and hands-on formats have a more lasting effect than theory — they promote understanding, responsiveness and personal responsibility.
- Raising awareness is not a project, but a process: Awareness work requires continuity. Initiatives such as HCSD show how learning, exchange and prevention can be sustainably anchored.
- Cyber security doesn't end at national borders: Different security cultures and cross-border cooperation offer great potential for new impulses.
- Security is a joint task: Whether IT, HR, administration, production or management — every role in the company contributes to digital security — and every perspective counts. Read more about this in this blog post as well.
Outlook: Moving forward with a tailwind
Three times as many topics and speakers as in 2024, a strong program and consistently positive feedback — over 500 completed feedback questionnaires clearly show that HCSD is hitting a nerve — professionally and personally. Many participants emphasised that they were able to gain concrete impetus not only for their work, but also for their private lives.
The numerous and constructive feedback motivates us to further develop the initiative together with our partners — in terms of content, organisation and internationally. In the next year, we would like to involve even more colleagues, both within and across national borders, and explore new formats. Because one thing is clear: Lift up security, together remains our way — and we've only just begun.
