IT Consulting & Security

Precise analysis, practical hardening, and clear recommendations — so your systems stay resilient before a security incident occurs.

Prevention over reaction

IT security is not a one-time state, but an ongoing process. In an era of increasing cyber risks, targeted system hardening is one of the most effective ways to reduce your attack surface. I don’t just check your existing infrastructure for known vulnerabilities — I optimize configurations so systems become fundamentally more robust against malware, misconfigurations, and unauthorized access. The goal is a reliable security baseline — technically sound, transparent, and practical for everyday operations.

Focus: System hardening for NAS & SMEs

I place particular emphasis on securing central storage systems (NAS), such as Synology or QNAP. Especially in small businesses, these systems are often the core platform for files, backups, and shared data — yet they’re frequently run with default configurations. I help you set up VPN access correctly, disable unnecessary services consistently, and establish clear permission models that prevent data loss or unauthorized access when it matters most.

FAQ: How a security check works

Do I need to interrupt operations for the analysis?

No. Most assessments are performed passively — for example through configuration reviews and log analysis — or within coordinated time windows. If active tests are useful, they are agreed in advance and planned so day-to-day operations are not disrupted.

Will I receive a written report?

Yes. You will receive a prioritized overview with concrete recommendations, sorted by urgency and written in clear language. The recommendations serve as a solid basis for decisions and implementation.

Personal consulting & absolute discretion Trust, responsibility and identity in IT consulting

IT security is built on trust. When I analyze your systems, you give me insight into the heart of your business — into data, processes, and long-grown structures. Accordingly high are my standards for discretion, diligence, and ethical responsibility.

As an owner-led IT service provider in Berlin, I work deliberately independently and personally. My company stands for an open, non-judgmental environment in which each client’s individual reality is respected. These values are just as crucial to a trusting partnership on equal footing as technical excellence. In a world of one-size-fits-all solutions, I offer you a protected space for honest and discreet consulting.

With more than 30 years of professional experience in Berlin, I have learned that sustainable IT security is not achieved through technology alone, but through reliability, clear communication, and honest consulting on equal footing. You won’t receive automated, off-the-shelf reports from me, but a well-founded, independent assessment that fully respects your specific requirements and your privacy.
