Testimonial - Siemens

“Siemens is a leader in digital transformation and our Congleton factory is considered to be a ‘lighthouse’ facility - showcasing new technologies. In this context, secure management with full traceability and revocability of our service partners’ digital access is critical for optimum process efficiency and seamless operations. After an incredibly smooth pilot phase at Congleton, we are in production now and hope to recommend the solution to other Siemens industrial sites in the UK.”

assembly line


Electric motors can be found practically everywhere. Manufacturers of such equipment operate at a high capacity to fulfill various business demands. One unplanned downtime in the production can have negative consequences on customers’ side, whose production is stopped. The support team who is not necessarily on-site has to react immediately. WL Digital Doorman can be used to proactively grant your external users the required access to the impacted industrial machines.



Building trust remotely in the pharma industry has always been a challenge. Companies are the target of cyberattacks as research data and intellectual property (IP) represent a gold mine for malicious actors. While operating in a highly regulated environment, the risks of any data leaks are real and potentially endanger lives, in case an insider manages to interrupt a vaccine or drug production. WL Digital Doorman could fit perfectly with the need to maintain pharmaceutical operations by protecting critical assets and data from unauthorized users.
