Who We Are

About FM-NetSec Nordic — Network Security & Infrastructure Consulting

25+ years as a hands-on Network Security Architect and IT infrastructure consultant — applied to real environments, not theoretical frameworks.

Franz Matthies

Network Security Architect & Principal Engineer — FM-NetSec Nordic

With over 25 years of hands-on experience as a Network Security Architect and IT infrastructure consultant, Franz Matthies has built and secured networks for some of Europe's leading organisations — from financial institutions and media groups to enterprise data centres and Nordic SMEs.

His career spans senior technical roles at organisations including Hypoport SE and NTT Germany, where he gained deep exposure to complex, production-critical environments. That experience shapes a practice grounded in engineering reality rather than theoretical frameworks: security built in from the start, solutions designed to hold up under real operational conditions.

Based in Hällefors, Sweden, FM-NetSec Nordic serves clients across the Nordic region and DACH markets — in Swedish, German, and English. The practice operates as a lean, expert-led engagement: no unnecessary layers between client and engineer, and no recommendations driven by vendor relationships or sales targets.

Engineering that serves the business.

Security by Design

Security is embedded in every architectural and technical decision — not added as an afterthought. The result is infrastructure that is inherently more resilient and easier to audit.

Technical Integrity

Engineering-focused solutions, grounded in technical merit. Transparency over vendor-driven approaches and marketing claims — recommendations are made on the basis of what actually works.

Practical Alignment

Solutions are implemented in actual operational environments — not only defined on whiteboards. The test of any design is whether it holds up under real-world conditions.

FM-NetSec Nordic provides network security assessments, architecture design, and incident troubleshooting for SMEs and enterprises in Sweden, Germany, Austria, Switzerland, Norway, Denmark, and Finland — drawing on more than 25 years of hands-on experience in data centre infrastructures, software-defined networking (SDN), and enterprise network security.

Technical Expertise

Deep, hands-on competence across the technologies that underpin modern enterprise and SME infrastructures.

Cisco & Enterprise Networking

Deep hands-on expertise with Cisco-based environments: routing protocols, switching architectures, firewall configurations, and full enterprise network design — from campus LAN to WAN edge.

Ubiquiti / UniFi

Professional deployment and ongoing management of Ubiquiti solutions — balancing enterprise-grade reliability with cost-effective implementation for organisations that need performance without unnecessary complexity.

Software-Defined Networking (SDN)

Modern SDN concepts applied to real infrastructure challenges — simplifying operations, improving visibility, and enabling greater control without sacrificing stability or maintainability.

Data Centre Infrastructures

Designing and securing data centre networks for stability, redundancy, and performance — with a focus on operational clarity and the ability to maintain the environment under pressure.

A Long-term Technical Partner

FM-NetSec Nordic operates as a trusted long-term technical partner — enabling organisations to build and maintain secure, stable networks that support business continuity, data protection, and sustainable growth. Active across the Nordic region and DACH markets, the focus is on relationships built on technical credibility and consistent delivery.
