A professional, licensable network protocol library designed specifically for manufacturers of entertainment lighting hardware and software. Rather than requiring engineering teams to build complex network stacks from scratch or attempt to retrofit legacy code with cybersecurity features: QubiCore provides a complete, pre-built, and thoroughly tested protocol implementation. The library natively supports essential industry protocols (including Art-Net, sACN, and RDMnet) and integrates the secure Sig-Net framework. This secure by design architecture provides developers with an efficient and reliable path to building CRA-defensible products that comply with the EU Cyber Resilience Act (CRA) prior to the December 2027 enforcement deadline.
