Niklas Nengelken

Based in Köln, Niklas Nengelken operates as an independent IT consultancy specializing in dental practices (Zahnarztpraxen) across Germany. Founded in 2024 as a small, one-person operation, the practice positions itself as a neutral auditor rather than a system house that both builds and operates a practice's IT — the stated principle being that no one should let the same party who constructed a system also certify it as safe. Clients are contract dental practices required to meet §390 SGB V IT security requirements, a KZBV directive substantially revised on 1 July 2025 with updated obligations becoming mandatory from 2 January 2026, carrying risks of fines, professional consequences, and insurance exclusions for non-compliant practices. Services center on three areas delivered by a certified security consultant with enterprise-sector experience: IT security audits against §390 SGB V, offered as a short quick-check (60-90 minutes), a full audit, or ongoing support, each concluding with a written report and prioritized recommendations; SEO and AI-SEO work focused on local visibility, including Google Business Profile optimization, structured data, and optimization for AI search tools such as ChatGPT and Perplexity; and AI consulting for practice operations, covering patient communication, documentation, and marketing, including setup and staff training. The process runs in three steps — an initial 15-20 minute phone or video consultation, the audit itself, and a results report with action items. A free initial consultation and a downloadable IT emergency plan for practices are offered via the website.
