effexx Unternehmensgruppe Tech Stack

Systems integrator for security, telecom, IT, and renewable energy

IT Services and IT Consulting Netphen, Nordrhein-Westfalen 201–500 employees Founded 1974 Self-Owned

effexx Unternehmensgruppe is a mid-market systems integrator founded in 1974, operating across five verticals: security systems, telecommunications, IT infrastructure, software development, and renewable energy installations. The hiring mix—eight security roles, seven engineering, two sales—reflects an organization tilted toward technical delivery and installation; combined with active projects in security system deployment, photovoltaic planning, and infrastructure buildout, this indicates effexx competes on project execution and bespoke solutions rather than platform software. Stack depth (C#, Java, ASP.NET Core, JavaScript) suggests custom application work embedded in larger system integrations.
