Freelancer profile translated to English.
Back to original languageAbout Johannes
I design and build (hybrid) Security Operations Centers. In doing so, I implement processes, accelerate decision-making, and make security measurable.
I help my clients make IT security more effective in terms of personnel, processes, and architecture, without violating applicable regulatory requirements or neglecting budget constraints.
I ensure the smooth collaboration between all stakeholders by taking on the intermediary role between management, IT, HR, legal department, data protection officer, and external solution providers.
My clients in the banking sector and medium-sized businesses value my precision and determination as much as my human sensitivity in dealing with complex issues.
Cyber Security Project Management, Frameworks, Optimizations, and Engineering with leadership of large teams in many areas of IT security.
Over 10 years of experience in international companies and medium-sized businesses. Automotive, Defence, Healthcare, Public Sector, KRITIS, Finance. I also help you reduce costs by analyzing existing structures, optimizing them, and taking over renegotiations of contracts.

Reviewed on 12/20/2022
Johannes and sequrium supported us in setting up a SIEM system with the analysis of business-critical applications, coordinated knowledge transfer, and the design of extensive use cases. In addition, sequrium supported us in the technical setup of a Security Operations Center for a client in the banking sector. The collaboration was excellent, and both projects were completed on time and with high quality, despite high complexity and some challenges.
