Profit from sustainable IT
"Sustainable Software": high security & data sovereignty by decentralized Open Source architectures
Open source software makes it possible to build long-term reliable and secure systems that exactly meet your requirements. Open Source software is free of charge and transparent, providing you independence of software companies that are very interested in your data. Take advantage of these benefits and become the master of your data and IT again! Among other things, I will show you simple possibilities that Edward Snowden considers good.
"Sustainable Hardware": durable and energy-saving hardware with simple maintenance
High-quality devices are reliable from 5-8 years, cheap to maintain and purchase as second-hand products. Minimize your technological, environmental, and financial footprints by using IT equipment with low investment, maintenance and energy costs. An increasing number of manufacturers are focused on fair and resource-conserving production processes.
The result: reduced costs, improved reliability, increased security and eco-friendly IT.
With sustainable software and hardware, you can simultaneously save money and reduce your ecological footprint. In addition, you benefit from reliable and secure systems with full control over your data. Get involved with this sustainable digital-electronic movement and you'll experience benefits exceeding your new investment.
