“Right from the start, communication was very practical and without sales talk. Our administrators gave me similar feedback on the implementation phase: Very uncomplicated and consistently positive communication, which makes you motivated to face even difficult internal tasks. We are absolutely satisfied with the project results and would recommend ProSec to other companies.”

Raimund Zimmermann is IT Security Manager at DEHN SE, an international manufacturer of secure protection against the dangers of lightning and surges for people, buildings, electrical and electronic devices and systems.

Our experts had a lot of fun working on the project with Mr. Zimmermann and the Operations Security Team (OpSec) at DEHN: Our project partners were extremely motivated and were able to gain a lot of knowledge transfer and specific insights through active exchange. A 100% positive experience for us too!

“'Only a real attack achieves a real result.' Nothing has proven truer than this Prosec credo. Your concept and professional approach round off our implemented security measures - from Next Generation FW to SIEM & SOC. We would not have been able to achieve the goal of finding the famous catch that we or service providers have forgotten in order to be able to close potential security gaps without Prosec. Prosec thinks like hackers and not in security solutions. This is your strength and the added value for VRM.”

Dominique Doré is in charge of IT at VRM, a media company for newspapers and advertising papers in print and digital based in Mainz.

Before our project, Mr. Doré had already worked intensively on expanding the cyber resilience of his company. The simulated attacks and the subsequent work-up with Mr. Doré brought our team particular joy!

“ ProSec has been a reliable partner for us for years to improve our IT security. We started with an extensive penetration test in which the security professionals from ProSec showed us optimization potential for IT security, evaluated it and then later reliably implemented it together with our IT department. We are now receiving regular support to further improve the level of security we have achieved. For me, as the person responsible for management, the regular status meetings held by ProSec's project manager provide a quick overview of all relevant security gaps. This is also understandable for IT laypeople and gives me a good and secure feeling that I can fulfill my responsibility in this area.”
