Garderos - Designed for extremes, trusted for a lifetime. Garderos is a Germany-based manufacturer of smart grid routers for secondary substation automation. Our focus is on product longevity, as electricity DSO's have been asking for longer and longer product lifecycles, to protect their investments. Their understanding of product lifecycle is: the time period where support for software, security updates and hardware support is provided. Garderos offers a product lifecycle of at least 15 years. Besides the longevity of our substation routers, we offer a scalable HTTPS-based element manager to manage router firmware and configuration. This product is already field-proven in European DSO projects for deployments of tens of thousands of routers.
