SDN Sicherheitsdienst Nürnberg

What SDN Sicherheitsdienst Nürnberg does

SDN Protection AG (formerly SDN Sicherheitsdienst Nürnberg e.K.) is a Mid-sized German security services provider headquartered in Nuremberg, Bayern, offering an integrated portfolio that spans physical guarding, mobile patrol, event security, retail loss prevention, cash and entry control, certified alarm monitoring, and specialized close protection. The company was founded in 2008 by Lars Müller as a one-person operation and has grown to over 150 employees, reorganizing from a sole proprietorship to an Aktiengesellschaft in 2025. Its technical foundation is a VdS-certified 24/7 Notruf- und Serviceleitstelle (alarm and service control center) integrated with fire, intrusion, and video systems, complemented by a proprietary Wächterkontrollsystem (guard control system) that transmits patrol observations in real time and GPS-based vehicle tracking.

The customer base is diversified across commercial and industrial enterprises, government and public institutions, event organizers, retail operators, and high-profile individuals served through the SDN Close Protection subsidiary. Named references include UEFA Euro 2024, Bardentreffen Nuremberg, Klassik Open Air Nuremberg, multiple Landesgartenschauen (Tirschenreuth 2013, Pfaffenhofen 2017, Apolda 2017), and 1. FC Nürnberg. Geographic coverage is rooted in the Nuremberg metropolitan region but extends across Germany (with regional job postings in Bayern, Baden-Württemberg, NRW, and Saarland), Europe (England, France, Netherlands, Austria, Russia), and selectively worldwide.

Revenue is generated primarily through recurring service contracts (subscription-style ongoing engagements) billed at hourly rates governed by the Tarifvertrag Bewachungsgewerbe and augmented by project-based professional services (security consulting, concept development, expert witness, close protection, armed services, chauffeur, and cybersecurity). The go-to-market is direct enterprise field sales supported by a 24/7 hotline and an inside-sales function, with regional marketing driven by Google reviews, social media, and local sports sponsorships. SDN is founder-owned, holds no external funding, and is led by Lars Müller, who simultaneously serves as President of the BVMS industry association.
