What our customers say:

“Quick help, professional support and a strong network – we are grateful!


Like many other companies, we fell victim to a cyberattack. One of our partners referred us to Experts4Cyber – and the very next morning after the incident, the first coordination meeting took place with all the partners involved with whom experts4cyber works.

From the very beginning, we felt we were in the best hands. The support was consistently professional, structured, and solution-oriented. The entire Experts4Cyber network operated at the highest level—every party involved performed outstandingly.

Thanks to this quick and efficient collaboration, we were able to go back online in less than 3.5 weeks – thus averting major losses. We are very grateful for this support and can wholeheartedly recommend Experts4Cyber."

"Professional support in critical situations!

We contacted Experts4Cyber following a cyberattack and received immediate, expert assistance. The Experts4Cyber Response team not only responded quickly, but also with the necessary calm and professionalism that are crucial in such a crisis situation. The consultation was structured and targeted from the outset. Complex technical issues were explained clearly, clear recommendations for immediate damage limitation were provided, and preventative measures were initiated.

We were particularly impressed by the combination of technical expertise and the ability to develop well-thought-out solutions, even under time pressure. The Experts4Cyber team not only provided tremendous support in managing the immediate crisis but also helped to sustainably improve our IT security structures. We can fully recommend Experts4Cyber and are grateful for the professional support in a very stressful situation for everyone involved."

"Targeted and prudent crisis management meets effective teamwork!


Experts4Cyber provided us with outstanding support during one of the most serious corporate crises (a cyberattack) in our 99-year history through their focused, level-headed, and communicative approach. Experts4Cyber's experience helped us, especially at the beginning of the cyberattack, to remain calm, analyze the situation, and initiate and follow up on appropriate countermeasures. After what felt like just a few hours, the external and internal crisis management teams merged into a well-functioning team that made a significant contribution to restoring the functionality of our IT systems so that we can now face the next 99 years.
