The slash4 group is a growing network of experienced IT consultants. We are working in big projects – programming, designing, administrating, planning – to find tailored solutions for our clients. We love to learn – and we love to share our know how. With this platform we are offering consulting services, online learning courses, howto articles, simple concepts and more … See this video for a short introduction:



Our main focus is to “simplify IT”


We will NEVER offer you a proprietary software with huge license costs … but we will provide:

  • simple IT architectures
  • simple concepts
  • open source software to reduce costs
  • clean and fast development of simple and tailored solutions
  • keeping things simple makes it easier to keep them secure
  • fast and continuous learning
  • automate what can be automated
  • outsource every job that can be outsourced


We have been working for customers like Siemens, Atos, Allianz, Deutsche Telekom, 1&1, international Banks, SAP since 1999 … We have seen how these enterprises run their IT departments. And you would expect that those global players would be best in class – but this is not true. Those IT departments have grown over decades and the organization and workflows became more complicated year after year.

Stop growing your bureaucracy – make a cut and start simple again.

We are working together with freelancers all over the world (Germany, Switzerland, UK, India, China, Philippines, South America, etc.). We have a strong network, experts in many fields.


We are experts in many technologies like:


  • IT Security (Penetration Testing, Code Review, Security Analysis, Secure Operation Concepts, …)
  • Linux
  • Web Technologies (Apache, nginx, haproxy, Loadbalancing, Tomcat, JBoss, …)
  • Big Data (Hadoop, Hive, MongoDB, …)
  • Python Development (Django, Flask, …)
  • Deployment Automation
  • Continuous Integration
  • Continuous Delivery
  • DevOps
  • Web Development (Design, Blog, WordPress, CMS, …)
  • Business Automation (automate your daily tasks so you have more time to work on your business strategy)
  • Workflow Automation (work with components, Shop->Order->Payment->Shipping->Controlling->Feedback …)
  • Outsourcing
